The tributary system of China (simplified Chinese: 中华朝贡体系; traditional Chinese: 中華朝貢體系; pinyin: Zhōnghuá cháogòng tǐxì), or Cefeng system (simplified Chinese: 册封体制; traditional Chinese: 冊封體制; pinyin: Cèfēng tǐzhì) at its height was a network of loose international relations centered around China which facilitated trade and foreign relations by acknowledging China's hegemonic role within a Sinocentric world order. It involved multiple relationships of trade, military force, diplomacy and ritual. The other states had to send a tributary envoy to China on schedule, who would kowtow to the Chinese emperor as a form of tribute, and acknowledge his superiority and precedence. The other countries followed China's formal ritual in order to keep the peace with the more powerful neighbor and be eligible for diplomatic or military help under certain conditions. Political actors within the tributary system were largely autonomous and in almost all cases virtually independent.
Scholars differ on the nature of China's relations with its neighbors in traditional times. Many describe a system that embodied a collection of institutions, social and diplomatic conventions, and institutions that dominated China's contacts with the non-Chinese world for two millennia, until the collapse of the system around the end of the 19th century. Other scholars like Odd Arne Westad see a variety of relationships that differed in character, not an overall "tributary system". They suggest a Sinocentric system, in which Chinese culture was central to the self-identification of many elite groups in the surrounding Asian countries. By the late 19th century, China had become part of a European-style community of sovereign states and established diplomatic relations with other countries in the world following international law.
Some scholars have suggested that the tributary system is a model for understanding international relations in East Asia today, while others argue that the concept is misleading both about relations in early modern times and today.
Definition
The term "tribute system" is a Western invention. There was no equivalent term in the Chinese lexicon to describe what would be considered the "tribute system" today, nor was it envisioned as an institution or system. John King Fairbank and Teng Ssu-yu created the "tribute system" theory in a series of articles in the early 1940s to describe "a set of ideas and practices developed and perpetuated by the rulers of China over many centuries." The concept was developed and became influential after 1968, when Fairbank edited and published a conference volume, The Chinese World Order, with fourteen essays on China's pre-modern relations with Vietnam, Korea, Inner Asia and Tibet, Southeast Asia and the Ryukyus, as well as an Introduction and essays describing Chinese views of the world order. The model presents the tribute system as an extension of the hierarchic and nonegalitarian Confucian social order.
"Tribute", points out Peter C. Perdue, the historian of Qing dynasty foreign relations, is "the inadequate translation for gong, a term with multiple meanings in classical Chinese," since its "root meaning of gift giving from inferiors to superiors applied to all personal relationships...." Fairbank's concept of tribute system "turned a flexible practice with multiple meanings into an overly formalized ritual system" in which gong always had the same meanings and gong ritual was exclusively and predominately a marker of foreign relations, whereas the Qing conducted "many diverse forms of tributary ritual".
In practice
Legitimacy
The "tribute system" is often associated with a "Confucian world order", under which neighboring states complied and participated in the "tribute system" to secure guarantees of peace, investiture, and trading opportunities. One member acknowledged another's position as superior, and the superior would bestow investiture upon them in the form of a crown, official seal, and formal robes, to confirm them as king. The practice of investing non-Chinese neighbors had been practiced since ancient times as a concrete expression of the loose reign policy.
The rulers of Joseon, in particular, sought to legitimize their rule through reference to Chinese symbolic authority. On the opposite side of the tributary relationship spectrum was Japan, whose leaders could hurt their own legitimacy by identifying with Chinese authority. In these politically tricky situations, sometimes a false king was set up to receive investiture for the purposes of tribute trade.
Autonomy
In practice, the tribute system only became formalized during the early years of the Ming dynasty. Actors within the "tribute system" were virtually autonomous and carried out their own agendas despite sending tribute; as was the case with Japan, Korea, Ryukyu, and Vietnam. Chinese influence on tributary states was almost always non-interventionist in nature and tributary states "normally could expect no military assistance from Chinese armies should they be invaded".
Tribute
The "tribute" entailed a foreign court sending envoys and exotic products to the Chinese emperor. The emperor then gave the envoys gifts in return and permitted them to trade in China. Presenting tribute involved theatrical subordination but usually not political subordination. The political sacrifice of participating actors was simply "symbolic obeisance". Nor were states that sent tribute forced to mimic Chinese institutions, for example in cases such as the Inner Asians, who basically ignored the trappings of Chinese government. Instead they manipulated Chinese tribute practices for their own financial benefit.
The gifts doled out by the Ming emperor and the trade permits granted were of greater value than the tribute itself, so tribute states sent as many tribute missions as they could. In 1372, the Hongwu Emperor restricted tribute missions from Joseon and six other countries to just one every three years. The Ryukyu Kingdom was not included in this list, and sent 57 tribute missions from 1372 to 1398, an average of two tribute missions per year. Since geographical density and proximity was not an issue, regions with multiple kings such as the Sultanate of Sulu benefited immensely from this exchange.
After 1435, the Ming dynasty urged foreign delegations to leave and stopped offering transport assistance for visiting missions. The size of delegations was restricted from hundreds of people to less than a dozen and the frequency of tributary missions was also reduced.
The practice of giving gifts of greater value than the tribute itself was not practiced by the Mongol-led Yuan dynasty court with Goryeo. Gifts conferred by the Yuan were worth a fraction of the tribute offered by Goryeo.
Culture
Participation in a tributary relationship with a Chinese dynasty could also be predicated on cultural or civilizational motivations rather than material and monetary benefits. The Korean kingdom of Joseon did not treat the Manchu-led Qing dynasty, which invaded Joseon and forced it to become a tributary in 1636, in the same way as the Han-led Ming dynasty. Joseon had continued to support the Ming in their wars against the Qing despite incurring military retaliation from the latter. The Manchus were viewed as barbarians by the Korean court, which, regarding itself as the new "Confucian ideological center" in place of the Ming, continued to use the Ming calendar and era names in defiance of the Qing, despite sending tribute missions.
Meanwhile, Japan avoided direct contact with Qing China and instead manipulated embassies from neighboring Joseon and Ryukyu to make it falsely appear as though they came to pay tribute. Joseon Korea remained a tributary of Qing China until 1895, when the First Sino-Japanese War ended this relationship.
Rituals
The Chinese tributary system required a set of rituals from the tributary states whenever they sought relations with China as a way of regulating diplomatic relations. The main rituals generally included:
- The sending of missions by tributary states to China
- The tributary envoys' kowtowing before the Chinese emperor as "a symbolic recognition of their inferiority" and "acknowledgment of their status of a vassal state"
- The presentation of tribute and receipt of the emperor's "vassals' gifts"
- The investiture of the tributary state's ruler as the legitimate king of his land
After the completion of the rituals, the tributary states engaged in their desired business, such as trade.
History
Tributary relations emerged during the Tang dynasty, under the reign of Emperor Taizong, as Chinese rulers started perceiving foreign envoys bearing tribute as a "token of conformity to the Chinese world order".
The Ming founder Hongwu Emperor adopted a maritime prohibition policy and issued tallies to "tribute-bearing" embassies for missions. Missions were subject to limits on the number of persons and items allowed.
Korea
The Old Book of Tang and New Book of Tang recorded Silla sending women, 4 in total, all rejected, gold, silver among other things as tribute to the Tang dynasty.
If Silla indeed served China wholeheartedly by dispatching tributary ships one after another, why did King Beopheung use his own reign title? This is indeed confusing! From then on, Silla maintained this erroneous practice for many more years, even after Emperor Taizong had learned about it and reproved the Silla ambassador. Now, they eventually adopted the Tang reign title. Although a move out of necessity, we may still say that they have been able to correct their mistake.
— Kim Bu-sik (1075–1151) writing on the nature of Silla's tributary relationship with China
Goryeo's rulers called themselves "Great King" viewing themselves as the sovereigns of the Goryeo-centered world of Northeast Asia. They maintained their own Imperial style, in their setup of government institutions, administrative divisions and own tributary system.
As the struggle between the Northern Yuan and the Red Turban Rebellion and the Ming remained indecisive, Goryeo retained neutrality despite both sides pleading for their assistance in order to break this stalemate. As the Ming eventually gained the upper hand Goryeo paid an enormous tribute to Ming in February 1385 consisting of five thousand horses, five hundred jin of gold, fifty thousand jin of silver and fifty thousand bolts of cotton fabric in order to maintain their neutrality.
Japan
Early kings of Japan had formal diplomatic inquiries with the Jin dynasty and its successors and were appointed as "King of Wa". The Emperors of China commonly referred to the ruler of Japan as 倭寇王 wōkouwang (wakuō) meaning "King of Wa", while they themselves styled themselves as ōkimi, meaning "Great King" in relation to the Chinese emperor. Internally 天皇 tennō meaning "heavenly king" also used to put the ruler of Japan on the same level as the one of China.
Between 607 and 838, Japan submitted and sent 19 missions to China under the Sui and Tang dynasties. The nature of these bilateral contacts evolved gradually from political and ceremonial acknowledgment to cultural exchanges; and the process accompanied the growing commercial ties which developed over time. Knowledge was the principal objective of each expedition. For example: Priests studied Chinese Buddhism. Officials studied Chinese government. Doctors studied Chinese medicine. Painters studied Chinese painting. Approximately one third of those who embarked from Japan did not survive to return home.
Japan under the Ashikaga shogunate again became a tributary of China under the Ming dynasty in 1401. As a result, in 1404, Shogun Ashikaga Yoshimitsu, who held most of the de facto power in Japan, accepted the title "King of Japan" from the Ming, despite the nominal sovereign of Japan still residing in Kyōto. Yoshimitsu was the first and only Japanese ruler in the early modern period to accept a Chinese title. During the Muromachi period Japan accepted the Ming led worldview. This relationship continued until 1549 (except the 1411-1432 period) when Japan chose to end its recognition of China's regional hegemony and cancel any further tribute missions.
Membership in the tributary system was a prerequisite for any economic exchange with China. In exiting the system, Japan relinquished its trade relationship with China. Under the rule of the Wanli Emperor, Ming China quickly interpreted the Japanese invasions of Korea (1592–1598) which failed as a challenge to the Ming centered predominant worldview and order.
Thailand
Thailand was an important Chinese tributary state from the Sui dynasty (581–618), until the Taiping Rebellion of the late Qing dynasty during the mid-19th century. The Sukhothai Kingdom, the first unified Thai state, established official tributary relations with the Yuan dynasty during the reign of King Ram Khamhaeng, and Thailand remained a tributary of China until 1853.
Wei Yuan, the 19th century Chinese scholar, considered Thailand to be the strongest and most loyal of China's Southeast Asian tributaries, citing the time when Thailand offered to directly attack Japan to divert the Japanese in their planned invasions of Korea and the Asian mainland, as well as other acts of loyalty to the Ming dynasty. Thailand was welcoming and open to Chinese immigrants, who dominated commerce and trade, and achieved high positions in the government.
Vietnam
Vietnam was ruled by China for 1050 years. When Vietnam gained independence in 939, it became a tributary of China until 1885 when it became a protectorate of France with the Treaty of Huế (1884). The Lê dynasty (1428–1527) and Nguyễn dynasty (1802–1945) adopted the imperial Chinese system, with rulers declaring themselves emperors on the Confucian model and attempting to create a Vietnamese imperial tributary system while still remaining a tributary state of China.
Even though Vietnam was the only sinicized country in Southeast Asia, the Ming dynasty treated it with less respect than Korea or the Ryukyu Kingdom. The Hongwu Emperor was firmly opposed to military expeditions in Southeast Asia and only rebuked Vietnam's conquest of Champa, which had sent tribute missions to China seeking help. After the death of Emperor Hongwu, the Chinese intervened after a Vietnamese general, Le Qui Ly, usurped the Vietnamese throne.
The Malacca sultanate sent envoys to China to inform them that while returning to Malacca in 1469 from a trip to China, their ship had been driven by a storm to the coast of Vietnam and the Vietnamese killed, enslaved and castrated the survivors. The Malaccans reported that Vietnam was in control of Champa and that the Vietnamese sought to conquer Malacca, but the Malaccans did not fight back because of a lack of permission from the Chinese to engage in war. Malacca avoided reciprocating hostilities until they received a letter from the Ming dynasty, in which the Ming emperor scolded them, ordering the Malaccans to raise soldiers and retaliate if the Vietnamese attacked.
According to a 2018 study in the Journal of Conflict Resolution covering Vietnam-China relations from 1365 to 1841, "the Vietnamese court explicitly recognized its unequal status in its relations with China through a number of institutions and norms." Due to their participation in the tributary system, Vietnamese rulers behaved as though China was not a threat and paid very little military attention to it. Rather, Vietnamese leaders were clearly more concerned with quelling chronic domestic instability and managing relations with kingdoms to their south and west."
Ryukyu Kingdom
From the late 14th to early 16th centuries, the Ryukyu Kingdom served an important position in the Ming's tributary order, as they became a key intermediary for the Ming's trade with Northeast and Southeast Asia through goods funnelled into Ming-Ryukyu tribute missions. Ryukyu's intermediary role was also facilitated by Chinese diaspora communities who settled in Ryukyu and served positions in the Ryukyu court.
Maritime Southeast Asia
The Sultanate of Malacca and the Sultanate of Brunei sent tribute to the Ming dynasty, with their first rulers personally traveling to China with the Imperial fleets.
In the Philippine islands, trade with China is believed to have begun during the Tang dynasty, and expanded during the Song dynasty; by the second millennium AD, some polities were part of the tributary system of China, among them the Sultanate of Sulu.The tributary system of China (simplified Chinese: 中华朝贡体系; traditional Chinese: 中華朝貢體系; pinyin: Zhōnghuá cháogòng tǐxì), or Cefeng system (simplified Chinese: 册封体制; traditional Chinese: 冊封體制; pinyin: Cèfēng tǐzhì) at its height was a network of loose international relations centered around China which facilitated trade and foreign relations by acknowledging China's hegemonic role within a Sinocentric world order.
