The Arabian Desert is a vast desert wilderness in Western Asia. It stretches from Yemen to the Persian Gulf and Oman to Jordan and Iraq. It occupies most of the Arabian Peninsula, with an area of 2,330,000 square kilometers (900,000 sq mi). It is the fifth largest desert in the world, and the largest in Asia. At its center is Ar-Rub'al-Khali (The Empty Quarter), one of the largest continuous bodies of sand in the world.

Gazelles, oryx, sand cats, and spiny-tailed lizards are just some of the desert-adapted species that survive in this extreme environment, which features everything from red dunes to deadly quicksand. The climate is mostly dry (the major part receives around 100 mm (3.9 in) of rain per year but some very rare places receive as little as 50 mm), and temperatures oscillate between very high heat and seasonal night time freezes. It is part of the deserts and xeric shrublands biome and the Palearctic ecozone.

The Arabian desert ecoregion holds little biodiversity, although a few endemic plants grow here. Many species, such as the striped hyena, jackal and honey badger have become extirpated due to hunting, human encroachment and habitat destruction. Other species have been successfully re-introduced, such as the Arabian sand gazelle, and are protected at a number of reserves. Overgrazing by livestock, off-road driving, and human destruction of habitat are the main threats to this desert ecoregion.

Detailed geological features:
  • A corridor of sandy terrain known as the Ad-Dahna desert connects the large An-Nafud desert (65,000 km2 or 40,389 square miles) in the north of Saudi Arabia to the Rub' Al-Khali in the south-east.
  • The Tuwaiq escarpment is a region of 800 km (500 mi) arc of limestone cliffs, plateaux, and canyons.
  • Brackish salt flats: the quicksands of Umm al Samim.
  • The Wahiba Sands of Oman: an isolated sand sea bordering the east coast
  • The Rub' Al-Khali desert is a sedimentary basin elongated on a south-west to north-east axis across the Arabian Shelf. At an altitude of 1,000 metres (3,300 ft), the rock landscapes yield the place to the Rub' al-Khali, vast wide of sand of the Arabian desert, whose extreme southern point crosses the centre of Yemen. The sand overlies gravel or Gypsum Plains and the dunes reach maximum heights of up to 250 m (820 ft). The sands are predominantly silicates, composed of 80 to 90% of quartz and the remainder feldspar, whose iron oxide-coated grains color the sands in orange, purple, and red.

Ecology and natural resources

Natural resources available in the Arabian Desert include oil, natural gas, phosphates, and sulfur.

The Rub'al-Khali has very limited floristic diversity. There are only 37 plant species, 20 recorded in the main body of the sands and 17 around the outer margins. Of these 37 species, one or two are endemic. Vegetation is very diffuse but fairly evenly distributed, with some interruptions of near sterile dunes. Some typical plants are:
Other widespread species are:
Very few trees are found except at the outer margin (typically Acacia ehrenbergiana and Prosopis cineraria). Other species are a woody perennial Calligonum comosum, and annual herbs such as Danthonia forskallii.

The Asiatic cheetah and Asiatic lion used to be here. 

Climate

The Arabian Desert has a subtropical, hot desert climate, similar to the climate of the Sahara Desert; the world's largest hot desert. The Arabian Desert is actually an extension of the Sahara Desert over the Arabian peninsula. The climate is mainly hot and dry with plenty of sunshine throughout the year. The rainfall amount is generally around 100 mm, and the driest areas can receive between 30 and 40 mm of annual rain. Such dryness remains rare throughout the desert, however. There are few hyperarid areas in the Arabian Desert, in contrast with the Sahara Desert, where more than half of the area is hyperarid (annual rainfall below 50 mm). The sunshine duration in the Arabian Desert is very high by global standards, between 2,900 hours (66.2% of daylight hours) and 3,600 hours (82.1% of daylight hours), but it is typically around 3,400 hours (77.6% of daylight hours), thus clear-sky conditions prevail over the region and cloudy periods are intermittent. Even though the sun and moon are bright, dust and humidity cause lower visibility at ground level. The temperatures remain high all year round. Average high temperatures in summer are generally over 40 °C (104 °F) at low elevations, and can even soar to 48 °C (114.8 °F) at extremely low elevations, especially along the Persian Gulf near sea level. Average low temperatures in summer remain high, over 20 °C (68 °F) and sometimes over 30 °C (77 °F) in the southernmost regions. Record high temperatures are above 50 °C (122 °F) in much of the desert, due in part to very low elevation.

Political borders

The desert lies mostly in Saudi Arabia, extending into the surrounding countries of Egypt (Sinai), southern Iraq and southern Jordan. The Arabian desert is bordered by 5 countries. Bordering the Persian Gulf, there is an extension into Qatar and, further east, the region covers almost all of Abu Dhabi in the United Arab Emirates (UAE). The Rub'al-Khali crosses over from Saudi Arabia into western Oman and eastern Yemen

People, language and cultures

The area is home to several different cultures, languages, and peoples, with Islam as the predominant faith. The major ethnic group in the region is the Arabs, whose primary language is Arabic

Settlements

In the center of the desert lies Riyadh, the capital of Saudi Arabia, with more than 7 million inhabitants. Other large cities, such as Dubai, Abu Dhabi, or Kuwait City, lie on the coast of the Persian Gulf.

Ecological threats


Military activity

Weaponry used by the United States during the Gulf War also poses a huge risk to the environmental stability of the area. Tank columns in the desert plains may disrupt the fragile stability that exists in the desert currently. In 1991, the movement of US tanks over the desert damaged the top protective layer of the desert soil. As a result, a sand dune was released and has started slowly moving downhill. Some people fear this dune could ultimately reach Kuwait City.

Conservation

The conservation status of the desert is critical/endangered, with species including the sand gazelle and white oryx threatened, and honey badgers, jackals, and striped hyaenas already extirpated.

No formal protected areas exist, but a number of protected areas are planned for Abu Dhabi.

Oil spills

In January 1991 during the Gulf War, Iraqi forces released about 1.7 million m³ (11 million barrels) of oil from storage tanks and tankers directly into the Persian Gulf. In February, they also destroyed 1,164 Kuwaiti oil wells. It took nine months to extinguish these oil fires. These oil spills contaminated 1,000 km (620 mi) of Persian Gulf coast.

The result of the pollution was the death of thousands of water birds and serious damage to the Persian Gulf's aquatic ecosystem, particularly shrimp, sea turtles, dugongs, whales, dolphins and fish.
The damaged wells also released 10 million m³ (60 million barrels) of oil into the desert and formed lakes (total surface of 49 square kilometers).

The Gobi Desert (/ˈɡbi/) is a large desert or brushland region in Asia. It covers parts of Northern and Northeastern China and of Southern Mongolia. The desert basins of the Gobi are bounded by the Altai Mountains and the grasslands and steppes of Mongolia on the north, by the Taklamakan Desert to the west, by the Hexi Corridor and Tibetan Plateau to the southwest and by the North China Plain to the southeast. The Gobi is notable in history as the location of several important cities along the Silk Road

The Gobi is a rain shadow desert, formed by the Tibetan Plateau blocking precipitation from the Indian Ocean reaching the Gobi territory. 

Geography

The Gobi measures over 1,600 km (1,000 mi) from southwest to northeast and 800 km (500 mi) from north to south. The desert is widest in the west, along the line joining the Lake Bosten and the Lop Nor (87°–89° east). It occupies an arc of land 1,295,000 km2 (500,000 sq mi) in area as of 2007; it is the sixth-largest desert in the world and Asia's 2nd largest. Much of the Gobi is not sandy but has exposed bare rock. 

In its broadest definition, the Gobi includes the long stretch of desert extending from the foot of the Pamirs (77° east) to the Greater Khingan Mountains, 116°-118° east, on the border of Manchuria; and from the foothills of the Altay, Sayan, and Yablonoi mountain ranges on the north to the Kunlun, Altyn-Tagh, and Qilian mountain ranges, which form the northern edges of the Tibetan Plateau, on the south.

A relatively large area on the east side of the Greater Khingan range, between the upper waters of the Songhua (Sungari) and the upper waters of the Liao-ho, is reckoned to belong to the Gobi by conventional usage. Some geographers and ecologists prefer to regard the western area of the Gobi region (as defined above): the basin of the Tarim in Xinjiang and the desert basin of Lop Nor and Hami (Kumul), as forming a separate and independent desert, called the Taklamakan Desert.

Archeologists and paleontologists have done excavations in the Nemegt Basin in the northwestern part of the Gobi Desert (in Mongolia), which is noted for its fossil treasures, including early mammals, dinosaur eggs, and prehistoric stone implements, some 100,000 years old.

The Gobi is overall a cold desert, with frost and occasionally snow occurring on its dunes. Besides being quite far north, it is also located on a plateau roughly 910–1,520 metres (2,990–4,990 ft) above sea level, which contributes to its low temperatures. An average of approximately 194 millimetres (7.6 in) of rain falls annually in the Gobi. Additional moisture reaches parts of the Gobi in winter as snow is blown by the wind from the Siberian Steppes. These winds may cause the Gobi to reach −40 °C (−40 °F) in winter to 45 °C (113 °F) in summer.

However, the climate of the Gobi is one of great extremes, combined with rapid changes of temperature of as much as 35 °C (63 °F). These can occur not only seasonally but within 24 hours.

Extremes −47 to 34 °C (−53 to 93 °F) −42.2 to 39.0 °C (−44.0 to 102.2 °F)

In southern Mongolia, the temperature has been recorded as low as −32.8 °C (−27.0 °F). In contrast, in Alxa, Inner Mongolia, it rises as high as 37 °C (99 °F) in July. 

Average winter minimums are a frigid −21 °C (−6 °F), while summertime maximums are a warm 27 °C (81 °F). Most of the precipitation falls during the summer.

Although the southeast monsoons reach the southeast parts of the Gobi, the area throughout this region is generally characterized by extreme dryness, especially during the winter, when the Siberian anticyclone is at its strongest. The southern and central parts of the Gobi Desert have variable plant growth due to this monsoon activity. The more northern areas of the Gobi are very cold and dry, making it unable to support much plant growth; this cold and dry weather is attributed to Siberian-Mongolian high pressure cells. Hence, the icy sandstorms and snowstorms of spring and early summer plus early January (winter). 

Conservation, ecology, and economy

The Gobi Desert is the source of many important fossils finds, including the first dinosaur eggs, twenty-six of which, averaging 9 inches in length, were uncovered in 1923.

Despite the harsh conditions, these deserts and the surrounding regions sustain many animals, including black-tailed gazelles, marbled polecats, wild Bactrian camels, Mongolian wild ass and sandplovers. They are occasionally visited by snow leopards, brown bears, and wolves. Lizards are especially well-adapted to the climate of the Gobi Desert, with approximately 30 species distributed across its southern Mongolian border. The most common vegetation in the Gobi desert are shrubs adapted to drought. These shrubs included gray sparrow's saltwort (Salsola passerina), gray sagebrush, and low grasses such as needle grass and bridlegrass. Due to livestock grazing, the amount of shrubs in the desert has decreased. Several large nature reserves have been established in the Gobi, including Gobi Gurvansaikhan National Park, Great Gobi A and Great Gobi B Strictly Protected Area

The area is vulnerable to trampling by livestock and off-road vehicles (effects from human intervention are greater in the eastern Gobi Desert, where rainfall is heavier and may sustain livestock). In Mongolia, grasslands have been degraded by goats, which are raised by nomadic herders as source of cashmere wool.

Large copper deposits are being mined by Rio Tinto Group. The mine was and remains controversial. There was significant opposition in Mongolia's parliament to the terms under which the mine will proceed, and some are calling for the terms to be renegotiated. Specifically, the contention revolves primarily around the question of whether negotiations were fair (Rio Tinto is far better resourced) and whether Rio Tinto will pay adequate taxes on the revenues it derives from the mine (an agreement was reached whereby the operation will be exempt from windfall tax).

Desertification

The Gobi Desert is expanding at an alarming rate through desertification, most rapidly on the southern edge into China, which is seeing 3,600 km2 (1,390 sq mi) of grassland overtaken every year. Dust storms have increased in frequency in the past 20 years, causing further damage to China's agriculture economy.

The northern and eastern boundaries between desert and grassland are constantly changing. This is mostly due to the climate conditions before the growing season, which influence the rate of evapotranspiration and subsequent plant growth.

The expansion of the Gobi is attributed mostly to human activities. It is part of the broader consequences of anthropogenic climate change, but locally driven by deforestation, overgrazing, and depletion of water resources. China has tried various plans to slow the expansion of the desert, which have met with some small degree of success, but no major effects. The most recent project is called the Three-North Shelter Forest Program which features huge strips of newly planted trees, in hopes that the baby trees will live long enough to establish a forest ecosystem which would stabilize the soil, retain moisture, and act as a buffer against further desertification. Most of the trees planted have died.

The Three-North Shelter Forest Program (or "Green Great Wall") was a Chinese government tree-planting project begun in 1978, and set to continue through 2050. The goal of the program is to reverse desertification by planting aspen and other fast-growing trees on some 36.5 million hectares across some 551 counties in 12 provinces of northern China. From 1978 to about 2004, the survival rate for trees planted as part of the Three Norths Shelter Forest System Project was low (about 15%).

Ecoregions

The Gobi, broadly defined, can be divided into five distinct dry ecoregions, based on variations in climate and topography:
  • Eastern Gobi desert steppe, the easternmost of the Gobi ecoregions, covering an area of 281,800 km2 (108,804 sq mi). It extends from the Inner Mongolian Plateau in China northward into Mongolia. It includes the Yin Mountains and many low-lying areas with salt pans and small ponds. It is bounded by the Mongolian-Manchurian grassland to the north, the Yellow River Plain to the southeast, and the Alashan Plateau semi-desert to the southeast and east.
  • Alashan Plateau semi-desert, lies west and southwest of the Eastern Gobi desert steppe. It consists of the desert basins and low mountains lying between the Gobi Altai range on the north, the Helan Mountains to the southeast, and the Qilian Mountains and northeastern portion of the Tibetan Plateau on the southwest.
  • Gobi Lakes Valley desert steppe, ecoregion lies north of Alashan Plateau semi-desert, between the Gobi Altai range to the south and the Khangai Mountains to the north.
  • Dzungarian Basin semi-desert, includes the desert basin lying between the Altai mountains on the north and the Tian Shan range on the south. It includes the northern portion of China's Xinjiang province and extends into the southeastern corner of Mongolia. The Alashan Plateau semi-desert lies to the east, and the Emin Valley steppe to the west, on the China-Kazakhstan border.
  • Tian Shan range, separates the Dzungarian Basin semi-desert from the Taklamakan Desert, which is a low, sandy desert basin surrounded by the high mountain ranges of the Tibetan Plateau to the south and the Pamirs to the west. The Taklamakan Desert ecoregion includes the Desert of Lop.

Eastern Gobi desert steppe

The surface is extremely diversified, although there are no great differences in vertical elevation. Between Ulaanbaatar (48°00′N 107°00′E) and the small lake of Iren-dubasu-nor (43°45′N 111°50′E), the surface is greatly eroded. Broad flat depressions and basins are separated by groups of flat-topped mountains of relatively low elevation 150 to 180 m (490 to 590 ft)), through which archaic rocks crop out as crags and isolated rugged masses. The floors of the depressions lie mostly between 900 to 1,000 m (3,000 to 3,300 ft) above sea-level. Farther south, between Iren-dutiasu-nor and the Yellow River, comes a region of broad tablelands alternating with flat plains, the latter ranging at altitudes of 1000–1100 m and the former at 1,070 to 1,200 m (3,510 to 3,940 ft). The slopes of the plateaus are more or less steep, and are sometimes penetrated by "bays" of the lowlands.

As the border-range of the Hyangan is approached, the country steadily rises up to 1,370 m (4,490 ft) and then to 1,630 m (5,350 ft). Here small lakes frequently fill the depressions, though the water in them is generally salt or brackish. Both here and for 320 km (199 mi) south of Ulaanbaatar, streams are frequent and grass grows more or less abundantly. Through all the central parts, until the bordering mountains are reached, trees and shrubs are utterly absent. Clay and sand are the predominant formations; the watercourses, especially in the north, being frequently excavated 2 to 3 m (6 ft 7 in to 9 ft 10 in) deep. In many places in the flat, dry valleys or depressions farther south, beds of loess, 5 to 6 m (16 to 20 ft) thick, are exposed. West of the route from Ulaanbaatar to Kalgan, the country presents approximately the same general features, except that the mountains are not so irregularly scattered in groups but have more strongly defined strikes, mostly east to west, west-north-west to east-south-east, and west-south-west to east-north-east.

The altitudes are higher, those of the lowlands ranging from 1,000 to 1,700 m (3,300 to 5,600 ft), and those of the ranges from 200 to 500 m (660 to 1,640 ft) higher, though in a few cases they reach altitudes of 2,400 m (7,900 ft). The elevations do not form continuous chains, but make up a congeries of short ridges and groups rising from a common base and intersected by a labyrinth of ravines, gullies, glens and basins. But the tablelands, built up of the horizontal red deposits of the Han-gai (Obruchev's Gobi formation) which are characteristic of the southern parts of eastern Mongolia, are absent here or occur only in one locality, near the Shara-muren river. They are greatly intersected by gullies or dry watercourses. Water is scarce, with no streams, no lakes, no wells, and precipitation falls seldom. The prevailing winds blow from the west and northwest, and the pall of dust overhangs the country as in the Takla Makan and the desert of Lop. Characteristic of the flora are wild garlic, Kalidium gracile, wormwood, saxaul, Nitraria schoberi, Caragana, Ephedra, saltwort and the grass Lasiagrostis splendens. The taana wild onion Allium polyrrhizum is the main browse eaten by many herd animals, and Mongolians claim that this is essential to produce the correct, slightly hazelnut-like flavour of camel airag (fermented milk).

This great desert country of Gobi is crossed by several trade routes, some of which have been in use for thousands of years. Among the most important are those from Kalgan (at the Great Wall) to Ulaanbaatar (960 km (597 mi)); from Jiuquan (in Gansu) to Hami 670 km (416 mi); from Hami to Beijing (2,000 km (1,243 mi)); from Hohhot to Hami and Barkul; and from Lanzhou (in Gansu) to Hami.

Alashan Plateau semi-desert

The southwestern portion of the Gobi, known also as the Hsi-tau and the Little Gobi, fills the space between the great north loop of the Yellow River on the east, the Ejin River on the west, and the Qilian Mountains and narrow rocky chain of Longshou, 3,200 to 3,500 m (10,500 to 11,500 ft) in altitude, on the southwest. The Ordos Desert, which covers the northeastern portion of the Ordos Plateau, in the great north loop of the Yellow River, is part of this ecoregion. It belongs to the middle basin of the three great depressions into which Potanin divides the Gobi as a whole.

"Topographically," says Nikolai Przhevalsky, "it is a perfectly level plain, which in all probability once formed the bed of a huge lake or inland sea." He concludes this based on the level area of the region as a whole, the hard saldgine clay and the sand-strewn surface and, lastly, the salt lakes which occupy its lowest parts. For hundreds of kilometers, nothing can be seen but bare sands; in some places they continue so far without a break that the Mongols call them Tengger (i.e. sky). These vast expanses are absolutely waterless, nor do any oases relieve the unbroken stretches of yellow sand, which alternate with equally vast areas of saline clay or, nearer the foot of the mountains, with barren shingle. Although on the whole a level country with a general altitude of 1,000 to 1,500 m (3,300 to 4,900 ft), this section, like most other parts of the Gobi, is crowned by a chequered network of hills and broken ranges going up 300 m higher. The vegetation is confined to a few varieties of bushes and a dozen kinds of grasses and herbs, the most conspicuous being saxaul (Haloxylon ammondendron) and Agriophyllum gobicum. The others include prickly convolvulus, field wormwood (Artemisia campestris), acacia, Inula ammophila, Sophora flavescens, Convolvulus ammanii, Peganum and Astragalus species, but all dwarfed, deformed and starved. The fauna consists of little but antelope, wolf, fox, hare, hedgehog, marten, numerous lizards and a few birds, e.g. the sandgrouse, lark, stonechat, sparrow, crane, Henderson's ground jay (Podoces hendersoni), horned lark (Eremophila alpestris), and crested lark (Galerida cristata).

Dzungarian Basin semi-desert

The structure here is that of the mighty T'ien Shan, or Heavenly Mountains, running from west to east. It divides the northern one-third of Sinkiang from the southern two-thirds. On the northern side, rivers formed from the snow and glaciers of the high mountains break through barren foothill ranges and flow out into an immense, hollow plain. Here the rivers begin to straggle and fan out, and form great marshes with dense reed-beds. Westerners call this terrain the Dzungarian desert. The Chinese also call it a desert, but the Mongols call it a 'gobi'—that is, a land of thin herbage, more suitable for camels than for cows, but capable also, if herds are kept small and moved frequently, of sustaining horses, sheep, and goats. The herbage comprises a high proportion of woody, fragrant plants. Gobi mutton is the most aromatic in the world.
The Yulduz valley or valley of the Haidag-gol (43°N 83°E43°N 86°E) is a mini desert enclosed by two prominent members of the Shanashen Trahen Osh mountain range, namely the chucis and the kracenard pine rallies, running perpendicular and far from one another. As they proceed south, they transcend and transpose, sweeping back on east and west respectively, with Lake Bosten in between. These two ranges mark the northern and the southern edges respectively of a great swelling, which extends eastward for nearly twenty degrees of longitude. On its northern side, the Chol-tagh descends steeply, and its foot is fringed by a string of deep depressions, ranging from Lukchun (130 m (427 ft) below sea level) to Hami (850 m (2,789 ft) above sea-level). To the south of the Kuruk-tagh lie the desert of Lop Nur, the Kum-tagh desert, and the valley of the Bulunzir-gol. To this great swelling, which arches up between the two border-ranges of the Chol-tagh and Kuruk-tagh, the Mongols give the name of Ghashuun-Gobi or "Salt Desert". It is some 130 to 160 km (81 to 99 mi) across from north to south, and is traversed by a number of minor parallel ranges, ridges and chains of hills. Down its middle runs a broad stony valley, 40 to 80 km (25 to 50 mi) wide, at an elevation of 900 to 1,370 m (2,950 to 4,490 ft). The Chol-tagh, which reaches an average altitude of 1,800 m (5,900 ft), is absolutely sterile, and its northern foot rests upon a narrow belt of barren sand, which leads down to the depressions mentioned above.

The Kuruk-tagh is the greatly disintegrated, denuded and wasted relic of a mountain range which used to be of incomparably greater magnitude. In the west, between Lake Bosten and the Tarim, it consists of two, possibly of three, principal ranges, which, although broken in continuity, run generally parallel to one another, and embrace between them numerous minor chains of heights. These minor ranges, together with the principal ranges, divide the region into a series of long; narrow valleys, mostly parallel to one another and to the enclosing mountain chains, which descend like terraced steps, on the one side towards the depression of Lukchun and on the other towards the desert of Lop.

In many cases these latitudinal valleys are barred transversely by ridges or spurs, generally elevations en masse of the bottom of the valley. Where such elevations exist, there is generally found, on the east side of the transverse ridge, a cauldron-shaped depression, which some time or other has been the bottom of a former lake, but is now nearly a dry salt-basin. The surface configuration is in fact markedly similar to that which occurs in the inter-mount latitudinal valleys of the Kunlun Mountains. The hydrography of the Ghashiun-Gobi and the Kuruk-tagh is determined by these chequered arrangements of the latitudinal valleys. Most of the principal streams, instead of flowing straight down these valleys, cross them diagonally and only turn west after they have cut their way through one or more of the transverse barrier ranges.

To the highest range on the great swelling Grigory Grum-Grshimailo gives the name of Tuge-tau, its altitude being 2,700 m (8,858 ft) above the level of the sea and some 1,200 m (3,937 ft) above the crown of the swelling itself. This range he considers to belong to the Choltagh system, whereas Sven Hedin would assign it to the Kuruk-tagh. This last, which is pretty certainly identical with the range of Kharateken-ula (also known as the Kyzyl-sanghir, Sinir, and Singher Mountains), that overlooks the southern shore of the Lake Bosten, though parted from it by the drift-sand desert of Ak-bel-kum (White Pass Sands), has at first a west-northwest to east-southeast strike, but it gradually curves round like a scimitar towards the east-northeast and at the same time gradually decreases in elevation.

In 91° east, while the principal range of the Kuruk-tagh system wheels to the east-northeast, four of its subsidiary ranges terminate, or rather die away somewhat suddenly, on the brink of a long narrow depression (in which Sven Hedin sees a northeast bay of the former great Central Asian lake of Lop-nor), having over against them the écheloned terminals of similar subordinate ranges of the Pe-shan (Boy-san) system (see below). The Kuruk-tagh is throughout a relatively low, but almost completely barren range, being entirely destitute of animal life, save for hares, antelopes and wild camels, which frequent its few small, widely scattered oases. The vegetation, which is confined to these same relatively favoured spots, is of the scantiest and is mainly confined to bushes of saxaul (Haloxylon), anabasis, reeds (kamish), tamarisks, poplars, and Ephedra.

European exploration

The Gobi had a long history of human habitation, mostly by nomadic peoples. By the early 20th century, the region was under the nominal control of Manchu-China, and inhabited mostly by Mongols, Uyghurs, and Kazakhs. The Gobi Desert as a whole was known only very imperfectly to outsiders, and information was confined to observations by individual travellers from their respective itineraries across the desert. Among the European explorers who contributed to the understanding of the Gobi, the most important were the following:

Tibetan sovereignty debate

From Wikipedia, the free encyclopedia
https://en.wikipedia.org/wiki/Tibetan_sovereignty_debate

The Tibetan sovereignty debate refers to two political debates. The first is whether the various territories within the People's Republic of China (PRC) that are claimed as political Tibet should separate and become a new sovereign state. Many of the points in the debate rest on a second debate, about whether Tibet was independent or subordinate to China in certain parts of its recent history.

It is generally held that China and Tibet were independent  prior to the Yuan dynasty (1271–1368), and that Tibet has been ruled by the People's Republic of China (PRC) since 1959.

The nature of Tibet's relationship with China in the intervening period is a matter of debate:
  • The PRC asserts that Tibet has been a part of China since the Mongol Yuan dynasty.
  • The Republic of China (ROC) asserted that "Tibet was placed under the sovereignty of China" when the Qing dynasty (1644–1912) ended the brief Nepalese rule (1788-1792) from parts of Tibet in c. 1793.
  • The Tibetan Government in Exile asserts that Tibet was an independent state until the PRC invaded Tibet in 1949/50.
  • Some Western scholars maintain that Tibet and China were ruled by the Mongols during the Yuan dynasty, that Tibet was independent during the Chinese Ming dynasty (1368–1644), and that Tibet was ruled by China or at the very least subordinate to the Manchu Qing during much of the Qing dynasty.
  • Some Western scholars also maintain that Tibet was independent from c. 1912 to 1950, although it had extremely limited international recognition.

The government of the People's Republic of China contends that it has had control over Tibet since the Yuan dynasty (1271–1368).

The government of the Republic of China, which ruled mainland China from 1912 until 1949 and now controls Taiwan, had a cabinet-level Mongolian and Tibetan Affairs Commission in charge of the administration of Tibet and Mongolia regions from 1912. The commission retained its cabinet level status after 1949, but no longer executes that function. On 10 May 1943, Chiang Kai-shek asserted that "Tibet is part of Chinese territory... No foreign nation is allowed to interfere in our domestic affairs". He again declared in 1946 that the Tibetans were Chinese nationals. The Mongolian and Tibetan Affairs Commission was disbanded in 2017. 

In the late 19th century, China adopted the Western model of nation-state diplomacy. As the government of Tibet, China concluded several treaties (1876, 1886, 1890, 1893) with British India touching on the status, boundaries and access to Tibet. Chinese government sources consider this a sign of sovereignty rather than suzerainty. However, by the 20th century British India found the treaties to be ineffective due to China's weakened control over the Tibetan local government. The British invaded Tibet in 1904 and forced the signing of a separate treaty, directly with the Tibetan government in Lhasa. In 1906, an Anglo-Chinese Convention was signed at Peking between Great Britain and China. It incorporated the 1904 Lhasa Convention (with modification), which was attached as Annex. A treaty between Britain and Russia (1907) followed. Article II of this treaty stated that "In conformity with the admitted principle of the suzerainty of China over Tibet, Great Britain and Russia engage not to enter into negotiations with Tibet except through the intermediary of the Chinese Government." China sent troops into Tibet in 1908. The result of the policy of both Great Britain and Russia has been the virtual annexation of Tibet by China. China controlled Tibet up to 1912. Thereafter, Tibet entered the period described commonly as de facto independence, though it was only recognized by independent Mongolia as enjoying de jure independence.

In the 2000s the position of the Republic of China with regard to Tibet appeared to become more nuanced as was stated in the following opening speech to the International Symposium on Human Rights in Tibet on 8 September 2007 through the pro-Taiwan independence then ROC President Chen Shui-bian who stated that his offices no longer treated exiled Tibetans as Chinese mainlanders.

Legal arguments based on historical status

The position of the People's Republic of China (PRC), which has ruled mainland China since 1949, as well as the official position of the Republic of China (ROC), which ruled mainland China before 1949 and currently controls Taiwan, is that Tibet has been an indivisible part of China de jure since the Yuan dynasty of Mongol-ruled China in the 13th century, comparable to other states such as the Kingdom of Dali and the Tangut Empire that were also incorporated into China at the time.

The PRC contends that, according to international law and the Succession of states theory, all subsequent Chinese governments have succeeded the Yuan Dynasty in exercising de jure sovereignty over Tibet, with the PRC having succeeded the ROC as the legitimate government of all China.

De facto independence

The ROC government had no effective control over Tibet from 1912 to 1951; however, in the opinion of the Chinese government, this condition does not represent Tibet's independence as many other parts of China also enjoyed de facto independence when the Chinese nation was torn by warlordism, Japanese invasion, and civil war. Goldstein explains what is meant by de facto independence in the following statement:
...[Britain] instead adopted a policy based on the idea of autonomy for Tibet within the context of Chinese suzerainty, that is to say, de facto independence for Tibet in the context of token subordination to China. Britain articulated this policy in the Simla Accord of 1914.
While at times the Tibetans were fiercely independent-minded at other times Tibet indicated its willingness to accept subordinate status as part of China provided that Tibetan internal systems were left untouched and China relinquished control over a number of important ethnic Tibetan groups in Kham and Amdo. The PRC insists that during this period the ROC government continued to maintain sovereignty over Tibet. The Provisional Constitution of the Republic of China (1912) stipulated that Tibet was a province of the Republic of China. Provisions concerning Tibet in the Constitution of the Republic of China promulgated later all stress the inseparability of Tibet from Chinese territory, and the Central Government of China exercise of sovereignty in Tibet. In 1927, the Commission in Charge of Mongolian and Tibetan Affairs of the Chinese Government contained members of great influence in the Mongolian and Tibetan areas, such as the 13th Dalai Lama, the 9th Panchen Lama and other Tibetan government representatives. In 1934, on his condolence mission for the demise of the Dalai Lama, the Chinese General Huang Musong posted notices in Chinese and Tibetan throughout Lhasa that alluded to Tibet as an integral part of China while expressing the utmost reverence for the Dalai Lama and the Buddhist religion.

The 9th Panchen Lama traditionally ruled over one-third of Tibet. On 1 February 1925, the Panchen Lama attended the preparatory session of the "National Reconstruction Meeting" (Shanhou huiyi) intended to identify ways and means of unifying the Chinese nation, and gave a speech about achieving the unification of five nationalities, including Tibetans, Mongolians and Han Chinese. In 1933, he called upon the Mongols to embrace national unity and to obey the Chinese Government to resist Japanese invasion. In February 1935, the Chinese government appointed Panchen Lama "Special Cultural Commissioner for the Western Regions" and assigned him 500 Chinese troops. He spent much of his time teaching and preaching Buddhist doctrines - including the principles of unity and pacification for the border regions - extensively in inland China, outside of Tibet, from 1924 until 1 December 1937, when he died on his way back to Tibet under the protection of Chinese troops.

During the Sino-Tibetan War, the warlords Ma Bufang and Liu Wenhui jointly attacked and defeated invading Tibetan forces.

The Kuomintang government sought to portray itself as necessary to validate the choice of the Dalai Lama and Panchen Lama. When the current (14th) Dalai Lama was installed in Lhasa, it was with an armed escort of Chinese troops and an attending Chinese minister The Muslim Kuomintang General Bai Chongxi said that the Tibetans suffered under British repression, and he called upon the Republic of China to assist them in expelling the British. According to Yu Shiyu, during China's resistance war against Japanese invasion, Chiang Kai-shek ordered the Chinese Muslim General Ma Bufang, Governor of Qinghai (1937–1949), to repair the Yushu airport in Qinghai Province to deter Tibetan independence. In May 1943, Chiang warned that Tibet must accept and follow the instructions and orders of the Central Government, that they must agree and help to build the Chinese-India [war-supply] road, and that they must maintain direct communications with the Office of the Mongolian and Tibetan Affairs Commission (MTAC) in Lhasa and not through the newly established "Foreign Office" of Tibet. He sternly warned that he would "send an air force to bomb Tibet immediately" should Tibet be found to be collaborating with Japan. Official Communications between Lhasa and Chiang Kai-shek's government was through MTAC, not the "Foreign Office", until July 1949 just before the Communists' final victory in the civil war. The presence of MTAC in Lhasa was viewed by both Nationalist and Communist governments as an assertion of Chinese sovereignty over Tibet. Throughout the Kuomintang years, no country gave Tibet diplomatic recognition.

In 1950, after the People's Liberation Army entered Tibet, Indian leader Jawaharlal Nehru stated that his country would continue the British policy with regards to Tibet in considering it to be outwardly part of China but internally autonomous.

Foreign interventions

The PRC considers all pro-independence movements aimed at ending Chinese sovereignty in Tibet, including British attempts to establish control in the late 19th century and early 20th century, the CIA's backing of Tibetan insurgents during the 1950s and 1960s, and the Government of Tibet in Exile till the turn of the 21st century, as one long campaign abetted by Western imperialism aimed at destroying Chinese territorial integrity and sovereignty, or destabilizing China.

View of the Tibetan government and subsequent government in exile


Government of Tibet (1912–1951)

Flag of Tibet between 1912 and 1950. This version was introduced by the 13th Dalai Lama in 1912. It sports two Snowlions amongst other elements and still continues to be used by the Tibet Government in Exile, but is outlawed in the People's Republic of China.
 
A proclamation issued by 13th Dalai Lama in 1913 states, "During the time of Genghis Khan and Altan Khan of the Mongols, the Ming dynasty of the Chinese, and the Qing Dynasty of the Manchus, Tibet and China cooperated on the basis of benefactor and priest relationship. [...] the existing relationship between Tibet and China had been that of patron and priest and had not been based on the subordination of one to the other." He condemned that the "Chinese authorities in Szechuan and Yunnan endeavored to colonize our territory Chinese" in 1910–12 and stated that "We are a small, religious, and independent nation".

Tibetan passports

The Tibetan government issued passports to the first-ever Everest expedition in 1921. The Tibetan government also issued passports to subsequent British Everest expedition in 1924 and 1936. The 1938–39 German expedition to Tibet also received Tibetan passports.

The passport of Tsepon Shakabpa
 
In 2003, an old Tibetan passport was rediscovered in Nepal. Issued by the Kashag to Tibet's finance minister Tsepon Shakabpa for foreign travel, the passport was a single piece of pink paper, complete with photograph. It has a message in hand-written Tibetan and typed English, similar to the message by the nominal issuing officers of today's passports, stating that ""the bearer of this letter – Tsepon Shakabpa, Chief of the Finance Department of the Government of Tibet, is hereby sent to China, the United States of America, the United Kingdom and other countries to explore and review trade possibilities between these countries and Tibet. We shall, therefore, be grateful if all the Governments concerned on his route would kindly give due recognition as such, grant necessary passport, visa, etc. without any hindrance and render assistance in all possible ways to him." The text and the photograph is sealed by a square stamp belonging to the Kashag, and is dated "26th day of the 8th month of Fire-Pig year (Tibetan)" (14 October 1947 in the gregorian calendar).

The passport has received visas and entry stamps from several countries and territories, including India, the United States, the United Kingdom, France, Italy, Switzerland, Pakistan, Iraq and Hong Kong, but not China. Some visa do reflect an official status, with mentions such as "Diplomatic courtesy, Service visa, Official gratis, Diplomatic visa, For government official".

However, acceptance of a passport does not indicate recognition of independence, as for example the Republic of China passport is accepted by almost all the countries of the world, even though few of them recognize the ROC as a nation. 

Tibet Government in exile (post 1959)

In 1959, the 14th Dalai Lama fled Tibet and established a government in exile at Dharamsala in northern India. This group claims sovereignty over various ethnically or historically Tibetan areas now governed by China. Aside from the Tibet Autonomous Region, an area that was administered directly by the Dalai Lama's government until 1951, the group also claims Amdo (Qinghai) and eastern Kham (western Sichuan). About 45 percent of ethnic Tibetans under Chinese rule live in the Tibet Autonomous Region, according to the 2000 census. Prior to 1949, much of Amdo and eastern Kham were governed by local rulers and even warlords.

The view of the current Dalai Lama in 1989 was as follows:
During the 5th Dalai Lama's time [1617–1682], I think it was quite evident that we were a separate sovereign nation with no problems. The 6th Dalai Lama [1683–1706] was spiritually pre-eminent, but politically, he was weak and uninterested. He could not follow the 5th Dalai Lama's path. This was a great failure. So, then the Chinese influence increased. During this time, the Tibetans showed quite a deal of respect to the Chinese. But even during these times, the Tibetans never regarded Tibet as a part of China. All the documents were very clear that China, Mongolia and Tibet were all separate countries. Because the Chinese emperor was powerful and influential, the small nations accepted the Chinese power or influence. You cannot use the previous invasion as evidence that Tibet belongs to China. In the Tibetan mind, regardless of who was in power, whether it was the Manchus [the Qing dynasty], the Mongols [the Yuan dynasty] or the Chinese, the east of Tibet was simply referred to as China. In the Tibetan mind, India and China were treated the same; two separate countries.
The International Commission of Jurists concluded that from 1913 to 1950 Tibet demonstrated the conditions of statehood as generally accepted under international law. In the opinion of the commission, the government of Tibet conducted its own domestic and foreign affairs free from any outside authority, and countries with whom Tibet had foreign relations are shown by official documents to have treated Tibet in practice as an independent State.

The United Nations General Assembly passed resolutions urging respect for the rights of Tibetans in 1959, 1961, and 1965. The 1961 resolution calls for that "principle of self-determination of peoples and nations" applies to the Tibetan people. 

The Tibetan Government in Exile views current PRC rule in Tibet, including neighboring provinces outside Tibet Autonomous Region, as colonial and illegitimate, motivated solely by the natural resources and strategic value of Tibet, and in gross violation of both Tibet's historical status as an independent country and the right of Tibetan people to self-determination. It also points to PRC's autocratic policies, divide-and-rule policies, and what it contends are assimilationist policies, and regard those as an example of ongoing imperialism aimed at destroying Tibet's distinct ethnic makeup, culture, and identity, thereby cementing it as an indivisible part of China. That said, the Dalai Lama stated in 2008 that he wishes only for Tibetan autonomy, and not separation from China, under certain conditions, like freedom of speech and expression, genuine self-rule, and control over ethnic makeup and migration in all areas claimed as historical Tibet.

Third-party views

Tibet within the Manchu dynasty in 1820
 
During the rule of the Chinese Tang dynasty (618–907), Tibet and China were frequently at war, with parts of Tibet temporarily captured by the Chinese to become part of their territory. Around 650, the Chinese captured Lhasa. In 763, Tibet very briefly took the Chinese capital of Chang'an during the Tang civil war.

Most scholars outside of China say that during the Ming dynasty (1368–1644), Tibet was independent without even nominal Ming suzerainty. In contrast, since the mid-18th century it is agreed that China had control over Tibet reaching its maximum in the end of the 18th century. Luciano Petech, a scholar of Himalayan history, indicated that Tibet was a Qing protectorate.

The patron and priest relationship held between the Qing court and the Tibetan lamas has been subjected to varying interpretation. The 13th Dalai Lama, for example, knelt, but did not kowtow, before the Empress Dowager Cixi and the young Emperor while he delivered his petition in Beijing. Chinese sources emphasize the submission of kneeling; Tibetan sources emphasize the lack of the kowtow. Titles and commands given to Tibetans by the Chinese, likewise, are variously interpreted. The Qing authorities gave the 13th Dalai Lama the title of "Loyally Submissive Vice-Regent", and ordered to follow Qing's commands and communicate with the Emperor only through the Manchu Amban in Lhasa; but opinions vary as to whether these titles and commands reflected actual political power, or symbolic gestures ignored by Tibetans. Some authors claim that kneeling before the Emperor followed the 17th-century precedent in the case of the 5th Dalai Lama. Other historians indicate that the emperor treated the Dalai Lama as an equal Kneeling was a compromise allowed by the Qing court for foreign representatives, Western and Tibetan alike, as both parties refused to perform the kowtow. 

Tibetologist Melvyn C. Goldstein writes that Britain and Russia formally acknowledged Chinese authority over Tibet in treaties of 1906 and 1907; and that the 1904 British invasion of Tibet stirred China into becoming more directly involved in Tibetan affairs and working to integrate Tibet with "the rest of China."

The status of Tibet after the 1911 Xinhai Revolution ended the Qing dynasty is also a matter of debate. After the revolution, the Chinese Republic of five races, including Tibetans, was proclaimed. Western powers recognized the Chinese Republic, however the 13th Dalai Lama proclaimed Tibet's independence. Some authors indicate that personal allegiance of the Dalai Lama to the Manchu Emperor came to an end and no new type of allegiance of Tibet to China was established, or that Tibet had relationships with the empire and not with the new nation-state of China. Barnett observes that there is no document before 1950 in which Tibet explicitly recognizes Chinese sovereignty, and considers Tibet's subordination to China during the periods when China had most authority comparable to that of a colony. Tibetologist Elliot Sperling noted that the Tibetan term for China, Rgya-nag, did not mean anything more than a country bordering Tibet from the east, and did not include Tibet. Other Tibetologists write that no country publicly accepts Tibet as an independent state, although there are several instances of government officials appealing to their superiors to do so. Treaties signed by Britain and Russia in the early years of the 20th century, and others signed by Nepal and India in the 1950s, recognized Tibet's political subordination to China. The United States presented a similar viewpoint in 1943. Goldstein also says that a 1943 British official letter "reconfirmed that Britain considered Tibet as part of China." Nevertheless, Goldstein views Tibet as occupied. Stating that The Seventeen-Point Agreement was intended to facilitate the military occupation of Tibet.

Thomas Heberer, professor of political science and East Asian studies at the University of Duisburg-Essen, Germany, wrote: "No country in the world has ever recognized the independence of Tibet or declared that Tibet is an 'occupied country'. For all countries in the world, Tibet is Chinese territory." However, newly independent Mongolia and Tibet recognized each other by a treaty signed just after the fall of the Qing dynasty, and under international law, even non-recognition by other states does not negate even a unilateral declaration of independence. During the early 1990s governmental bodies, including the European Union and United States Congress, and other international organisations declared that Tibetans lacked the enjoyment of self-determination to which they are entitled and that it is an occupied territory.

Under the terms of the Simla Accord (1914), the British Government's position was that China held suzerainty over Tibet but not full sovereignty. By 2008, it was the only state still to hold this view. David Miliband, the British Foreign Secretary, described the old position as an anachronism originating in the geopolitics of the early 20th century. Britain revised this view on 29 October 2008, when it recognised Chinese sovereignty over Tibet by issuing a statement on its website. The Economist reported at that time that although the British Foreign Office's website did not use the word sovereignty, officials at the Foreign Office said "it means that, as far as Britain is concerned, 'Tibet is part of China. Full stop.'"

In 2008, European Union leader José Manuel Barroso stated that the EU recognized Tibet as integral part of China: On 1 April 2009, the French Government reaffirmed its position on the Tibet issue.

In 2014, U.S. President Barack Obama stated that "We recognize Tibet as part of the People's Republic of China. We are not in favor of independence."

This lack of legal recognition makes it difficult for international legal experts sympathetic to the Tibetan Government in Exile to argue that Tibet formally established its independence. On the other hand, in 1959 and 1960, the International Commission of Jurists concluded that Tibet had been independent between 1913 and 1950.

While Canadian foreign policy and Canada's policy toward Tibet is strictly limited to supporting human rights, Canada has nonetheless recognized that the Tibetan people's human rights expressly include their right to self-determination.

Genocide allegations

Groups such as the Madrid-based Committee to Support Tibet claim the death toll in Tibet since the 1950 People's Liberation Army invasion of Tibet to be 1,200,000 and have filed official charges of genocide against prominent Chinese leaders and officials. This figure has been disputed by Patrick French, a supporter of the Tibetan cause who was able to view the data and calculations, but rather, concludes a no less devastating death toll of half a million people as a direct result of Chinese policies.

According to an ICJ (International Commission of Jurists) report released in 1960, there was no "sufficient proof of the destruction of Tibetans as a race, nation or ethnic group as such by methods that can be regarded as genocide in international law" found in Tibet.

Other rights

(See Serfdom in Tibet controversy, Social classes of Tibet and Human rights in Tibet.) The PRC argues that the Tibetan authority under successive Dalai Lamas was also itself a human rights violator. The old society of Tibet was a serfdom and, according to reports of an early English explorer, had remnants of "a very mild form of slavery" prior to the 13th Dalai Lama's reforms of 1913.

Tibetologist Robert Barnett wrote about clerical resistance to the introduction of anything Anti-Buddhist that might disturb the prevailing power structure. Clergy obstructed modernization attempts by the 13th Dalai Lama.

Old Tibet had a long history of persecuting non-Buddhist Christians. In the years 1630 and 1742, Tibetan Christian communities were suppressed by the lamas of the Gelugpa Sect, whose chief lama was the Dalai Lama. Jesuit priests were made prisoners in 1630 or attacked before they reached Tsaparang. Between 1850 and 1880, eleven fathers of the Paris Foreign Mission Society were murdered in Tibet, or killed or injured during their journeys to other missionary outposts in the Sino-Tibetan borderlands. In 1881 Father Brieux was reported to have been murdered on his way to Lhasa. Qing officials later discovered that the murder cases were in fact covertly supported and even orchestrated by local lamaseries and their patrons—the native chieftains. In 1904, Qing official Feng Quan sought to curtail the influence of the Gelugpa Sect and ordered the protection of Western missionaries and their churches. Indignation over Feng Quan and the Christian presence escalated to a climax in March 1905, when thousands of the Batang lamas revolted, killing Feng, his entourage, local Manchu and Han Chinese officials, and the local French Catholic priests. The revolt soon spread to other cities in eastern Tibet, such as Chamdo, Litang and Nyarong, and at one point almost spilled over into neighboring Sichuan Province. The missionary stations and churches in these areas were burned and destroyed by the angry Gelugpa monks and local chieftains. Dozens of local Westerners, including at least four priests, were killed or fatally wounded. The scale of the rebellion was so tremendous that only when panicked Qing authorities hurriedly sent 2,000 troops from Sichuan to pacify the mobs did the revolt gradually come to an end. The lamasery authorities and local native chieftains' hostility towards the Western missionaries in Tibet lingered through the last throes of the Manchu dynasty and into the Republican period.

Three UN resolutions of 1959, 1961, and 1965 condemned human rights violation in Tibet. These resolutions were passed at a time when the PRC was not permitted to become a member and of course was not allowed to present its singular version of events in the region (however, the Republic of China on Taiwan, which the PRC also tries to claim sovereignty over, was a member of the UN at the time, and it equally claimed sovereignty over Tibet and opposed Tibetan self-determination). Professor and sinologist A. Tom Grunfeld called the resolutions impractical and justified the PRC in ignoring them.

Grunfeld questioned Human Rights Watch reports on human rights abuses in Tibet, saying they distorted the big picture.

According to Barnett, since Western powers and especially the United States used the Tibet issue in the 1950s and 1960s for cold war political purposes, the PRC is now able to get support from developing countries in defeating the last nine attempts at the United Nations to criticize China. Barnett writes that the position of the Chinese in Tibet would be more accurately characterized as a colonial occupation, and that such an approach might cause developing nations to be more supportive of the Tibetan cause.

The Chinese government ignores the issue of its alleged violations of Tibetan human rights, and prefers to argue that the invasion was about territorial integrity and unity of the State. Furthermore, Tibetan activists inside Tibet have until recently focused on independence, not human rights.

Leaders of the Tibetan Youth Congress which claims a strength of over 30,000 members are alleged by China to advocate violence. In 1998, Barnett wrote that India's military includes 10,000 Tibetans, a fact that has been causing China some unease. He further wrote that "at least seven bombs exploded in Tibet between 1995 and 1997, one of them laid by a monk, and a significant number of individual Tibetans are known to be actively seeking the taking up of arms; hundreds of Chinese soldiers and police have been beaten during demonstrations in Tibet, and at least one killed in cold blood, probably several more."

Chinadaily.com reported on the discovery of weapons subsequent to the protests by Buddhists monks on March 14, 2008: "Police in Lhasa seized more than 100 guns, tens of thousands of bullets, several thousand kilograms of explosives and tens of thousands of detonators, acting on reports from lamas and ordinary people."

On 23 March 2008, there was a bombing incident in the Qambo prefecture.

Self-determination

While the earliest ROC constitutional documents already claim Tibet as part of China, Chinese political leaders also acknowledged the principle of self-determination. For example, at a party conference in 1924, Kuomintang leader Sun Yat-sen issued a statement calling for the right of self-determination of all Chinese ethnic groups: "The Kuomintang can state with solemnity that it recognizes the right of self-determination of all national minorities in China and it will organize a free and united Chinese republic." In 1931, the CCP issued a constitution for the short-lived Chinese Soviet Republic which states that Tibetans and other ethnic minorities, "may either join the Union of Chinese Soviets or secede from it." It is notable that China was in a state of civil war at the time and that the "Chinese Soviets" only represents a faction. Saying that Tibet may secede from the "Chinese Soviets" does not mean that it can secede from China. The quote above is merely a statement of Tibetans' freedom to choose their political orientation. The possibility of complete secession was denied by Communist leader Mao Zedong in 1938: "They must have the right to self-determination and at the same time they should continue to unite with the Chinese people to form one nation". This policy was codified in PRC's first constitution which, in Article 3, reaffirmed China as a "single multi-national state," while the "national autonomous areas are inalienable parts". The Chinese government insists that the United Nations documents, which codifies the principle of self-determination, provides that the principle shall not be abused in disrupting territorial integrity: "Any attempt aimed at the partial or total disruption of the national unity and the territorial integrity of a country is incompatible with the purposes and principles of the Charter of the United Nations...."

Legitimacy

The PRC also points to what it claims are the autocratic, oppressive and theocratic policies of the government of Tibet before 1959, its toleration of existence of serfdom and slaves, its so-called "renunciation" of (Arunachal Pradesh) and its association with India and other foreign countries, and as such claims the Government of Tibet in Exile has no legitimacy to govern Tibet and no credibility or justification in criticizing PRC's policies. 

China claims that the People's Liberation Army's march into Tibet in 1951 was not without the support of the Tibetan people, including the 10th Panchen Lama. Ian Buruma writes:
...It is often forgotten that many Tibetans, especially educated people in the larger towns, were so keen to modernize their society in the mid-20th century that they saw the Chinese communists as allies against rule by monks and serf-owning landlords. The Dalai Lama himself, in the early 1950s, was impressed by Chinese reforms and wrote poems praising Chairman Mao.
Instances have been documented when the PRC government gained support from a significant portion of the Tibetan population, including monastic leaders, monks, nobility and ordinary Tibetans prior to the crackdown in the 1959 uprising. The PRC government and many Tibetan leaders characterize PLA's operation as a peaceful liberation of Tibetans from a "feudal serfdom system." (和平解放西藏).

When Tibet complained to the United Nations through El Salvador about Chinese invasion in November 1950—after Chinese forces entered Chamdo (or Qamdo) when Tibet failed to respond by the deadline to China's demand for negotiation--members debated about it but refused to admit the "Tibet Question" into the agenda of the U.N. General Assembly. Key stakeholder India told the General Assembly that "the Peking Government had declared that it had not abandoned its intention to settle the difficulties by peaceful means", and that "the Indian Government was certain that the Tibet Question could still be settled by peaceful means". The Russian delegate said that "China's sovereignty over Tibet had been recognized for a long time by the United Kingdom, the United States, and the U.S.S.R." The United Nations postponed this matter on the grounds that Tibet was officially an "autonomous nationality region belonging to territorial China", and because the outlook of peaceful settlement seemed good.

Subsequently, The Agreement Between the Central Government and the Local Government of Tibet on Method for the Peaceful Liberation of Tibet, also known as Seventeen-Point Agreement, was signed between delegates of China and Tibet on 23 May 1951. The Dalai Lama, despite the massive Chinese military presence, had ample time and opportunity to repudiate and denounce the Seventeen-Point Agreement. He was encouraged and instigated to do so with promise of public but not military support by the US, which by now had become hostile to Communist-ruled China.

On May 29, the 10th Panchen Erdeni (i.e. 10th Panchen Lama) and the Panchen Kampus Assembly made a formal statement, expressing their heartfelt support for the agreement. The statement indicated their resolution to guarantee the correct implementation of the agreement and to realize solidarity between the different ethnic groups of China and ethnic solidarity among the Tibetans; and on May 30, the 10th Panchen Erdeni telegrammed the 14th Dalai Lama, expressing his hope for unity and his vow to support the 14th Dalai Lama and the government of Tibet with the implementation of the agreement under the guidance of the Central Government and Chairman Mao.

The Agreement was finally accepted by Tibet's National Assembly, which then advised the Dalai Lama to accept it. Finally, on 24 October 1951, the Dalai Lama dispatched a telegram to Mao Zedong:
The Tibet Local Government as well as the ecclesiastic and secular People unanimously support this agreement, and under the leadership of Chairman Mao and the Central People's Government, will actively support the People's Liberation Army in Tibet to consolidate defence, drive out imperialist influences from Tibet and safeguard the unification of the territory and sovereignty of the Motherland.
On 28 October 1951, the Panchen Rinpoche [i.e. Panchen Lama] made a similar public statement accepting the agreement. He urged the "people of Shigatse to give active support" to carrying out the agreement.

Tsering Shakya writes about the general acceptance of the Tibetans toward the Seventeen-Point Agreement, and its legal significance:
The most vocal supporters of the agreement came from the monastic community...As a result many Tibetans were willing to accept the agreement....Finally there were strong factions in Tibet who felt that the agreement was acceptable...this section was led by the religious community...In the Tibetans' view their independence was not a question of international legal status, but as Dawa Norbu writes, "Our sense of independence was based on the independence of our way of life and culture, which was more real to the unlettered masses than law or history, canons by which the non-Tibetans decide the fate of Tibet...This was the first formal agreement between Tibet and Communist China and it established the legal basis for Chinese rule in Tibet." 
On March 28, 1959, premier Zhou Enlai signed the order of the PRC State Council on the uprising in Tibet, accusing the Tibetan government of disrupting the Agreement. The creation of the TAR finally buried the Agreement that was discarded back in 1959.

On April 18, 1959, the Dalai Lama published a statement in Tezpur, India, that gave his reasons for escaping to India. He pointed out that the 17 Point Agreement was signed under compulsion, and that later "the Chinese side permanently violated it". According to Michael Van Walt Van Praag, "treaties and similar agreements concluded under the use or threat of force are invalid under international law ab initio". According to this interpretation, this Agreement would not be considered legal by those who consider Tibet to have been an independent state before its signing, but would be considered legal by those who acknowledge China's sovereignty over Tibet prior to the treaty. Other accounts, such as those of Tibetologist Melvyn Goldstein, argue that under international law the threat of military action does not invalidate a treaty. According to Goldstein, the legitimacy of the treaty hinges on the signatories having full authority to finalise such an agreement; whether they did is up for debate.
