The Sino-Soviet border conflict was a seven-month undeclared military conflict between the Soviet Union and China in 1969, following the Sino-Soviet split. The most serious border clash, which brought the world's two largest communist states to the brink of war, occurred near Damansky (Zhenbao) Island on the Ussuri (Wusuli) River in Manchuria. Clashes also took place in Xinjiang.
In 1964, the Chinese revisited the matter of the Sino-Soviet border demarcated in the 19th century, originally imposed upon the Qing dynasty by the Russian Empire by way of unequal treaties. Negotiations broke down amid heightening tensions and both sides began dramatically increasing military presence along the border. Sino-Soviet relations worsened further following the Soviet invasion of Czechoslovakia in 1968. Border confrontations escalated in March 1969 when a group of People's Liberation Army troops engaged Soviet border guards on Zhenbao Island in Manchuria, resulting in considerable casualties on both sides. Further clashes occurred in August at Tielieketi in Xinjiang and raised the prospect of an all-out nuclear exchange. The crisis de-escalated after Soviet Premier Alexei Kosygin met with Chinese Premier Zhou Enlai in September, and a ceasefire was ordered with a return to the status quo ante bellum.
In order to counterbalance the Soviet threat, the Chinese government sought a rapprochement with the United States. This resulted in a secret visit to China by Henry Kissinger in 1971, which in turn paved the way for President Richard Nixon's official visit to China in 1972. Sino-Soviet relations remained sour after the conflict despite the re-opening of border negotiations, which continued inconclusively for a decade. Serious talks did not occur until 1991, when an agreement was reached shortly before the fall of the Soviet Union. The border issues were conclusively resolved between China and Russia following a treaty signed in 2003 and an additional agreement in 2008.
Background
History
Under the governorship of Sheng Shicai (1933–1944) in Northwest China's Xinjiang Province, China's Kuomintang recognized for the first time the ethnic category of a Uyghur people by following the Soviet ethnic policy. That ethnogenesis of a "national" people eligible for territorialized autonomy broadly benefited the Soviet Union, which organized conferences in Fergana and Semirechye (in Soviet Central Asia) to cause "revolution" in Altishahr (southern Xinjiang) and Dzungaria (northern Xinjiang).
Both the Soviet Union and the White Movement covertly allied with the Ili National Army to fight the Kuomintang in the Three Districts Revolution. Although the mostly Muslim Uyghur rebels participated in pogroms against Han Chinese generally, the turmoil eventually resulted in the replacement of Kuomintang rule in Xinjiang with that of the Chinese Communist Party.
Soviet historiography, more specifically "Uyghur Studies," was increasingly politicized to match the tension of the Sino-Soviet split of the 1960s and the 1970s. One Soviet Turkologist, Tursun Rakhminov, who worked for the Soviet Communist Party, argued that the modern Uyghurs had founded the ancient Toquz Oghuz Country (744–840), the Kara-Khanid Khanate (840–1212), and so forth. The premodern states' wars against Chinese dynasties were cast as struggles for national liberation by the Uyghur ethnic group. Soviet historiography was not consistent on those issues; when Sino-Soviet relations were warmer, for example, the Three Districts Revolution was portrayed by Soviet historians as part of opposition to the Kuomintang during the Chinese Civil War, not as an anti-Chinese bid for national liberation. The Soviets also encouraged migration of Uyghurs to its territory in Kazakhstan, along the 4,380 km (2,738 mi) border. In May 1962, 60,000 Uyghurs from Xinjiang Province crossed the frontier into the Soviet Union to flee the famine and economic chaos of the Great Leap Forward.
