On 1 October 1949, the
People's Republic of China was proclaimed by Mao Zedong, and by May 1950 the KMT had been expelled from
Mainland China, remaining in control of
Taiwan. With the creation of the People's Republic of China, the supreme political authority in the two countries became centred in two communist parties, both espousing revolutionary, Marxist–Leninist ideology: the CCP and the
Communist Party of the Soviet Union. The day after the PRC's founding, the Soviet Union terminated its diplomatic relations with the KMT and recognized the PRC. (2nd left) visiting
Stalin (2nd right) in Moscow, December 1949 In late 1949, Mao went to Moscow to seek economic help. Stalin kept him waiting for weeks, humiliating Mao in treatment worthy of a minor vassal. Stalin was focused on European matters and sought Mao's assistance in supporting the Vietnamese Communists against France in the
First Indochina War. Mao accepted Stalin's view of a "worldwide communist revolution" and agreed to share "the international responsibility" and support the Vietnamese communists. Stalin allowed
Kim Il Sung to launch the
Korean War. However, both Kim Il Sung and Stalin did not consider that the United States would intervene into that war immediately, if at all. Kim Il Sung could not sustain the attack against the
United States Army. When Kim Il Sung required military assistance from the Soviet Union and China, Mao agreed to send Chinese troops, but asked the
Soviet Air Forces to provide air cover. As the two leaders distrusted each other, Stalin agreed with sending Chinese troops to Korea, but refused to provide air cover. Since without the air cover from the Soviet Union, Mao once considered that China did not send troops into Korea, and Stalin at one time decided to give up the Korea Peninsula. In the immediate years after the PRC was proclaimed, the Soviet Union became its closest ally. Moscow sent thousands of Soviet engineers and workers, and trainloads of machinery and tools. During the 1950s, the Soviet Union was the largest supplier of machinery to
Chinese industries. The Sino-Soviet split was marked by small scale fighting in the
Sino-Soviet border conflict in 1969. Moscow considered a
preemptive nuclear strike. That never happened, but the Soviets did encourage
Uyghurs to
rebel against China. More important, China launched its own bid to control communist movements around the world, and in most cases local communist parties split between the two sponsors, confusing fellow travelers and weakening the overall communist movement in the
Third World. Beijing said the Soviet Union had fallen into the trap of
social imperialism, and was now seen as the greatest threat it faced. Mao made overtures to
Richard Nixon and the United States, culminating in the sensational
1972 Nixon visit to China.
Post-Mao era and stabilizing relations In 1976, Mao died and the
Gang of Four were
overthrown by
Premier Hua Guofeng. After a two-year continuation of Maoist orthodoxy, Hua was forced to cede power to
Deng Xiaoping, who began a
series of reforms intended to encourage
ideological pragmatism. With the PRC no longer espousing the
anti-revisionist notion of the
antagonistic contradiction between classes, relations between the two countries became gradually normalized. In 1979, however, the PRC
invaded Vietnam (which had, after a period of ambivalence, sided with the Soviet Union) in response to the
Vietnam's
invasion of Cambodia which overthrew the China-backed
Khmer Rouge from power. During the Sino-Soviet split, strained relations between China and the Soviet Union resulted in strained relations between China and the pro-Soviet
Afghan communist regime. China and
Afghanistan had neutral
relations with each other during the rule of King
Mohammed Zahir Shah. When the pro-Soviet Afghan communists
seized power in Afghanistan in 1978, relations between China and the Afghan communists quickly turned hostile. The Afghan pro-Soviet communists supported the Vietnamese during the Sino-Vietnamese War and blamed China for supporting Afghan anti-communist militants. China responded to the
Soviet invasion of Afghanistan by supporting the
Afghan mujahideen and ramping up their military presence near Afghanistan in Xinjiang. China acquired military equipment from the United States to defend itself from Soviet attack. China moved its training camps for the mujahideen from
Pakistan into China itself. Hundreds of millions worth of anti-aircraft missiles, rocket launchers and machine guns were given to the mujahideen by the Chinese. Chinese military advisers and army troops were present with the mujahideen during training. In 1980, China adopted a new Military Strategic Guideline that envisioned using a
combined arms approach and positional warfare to defend against a potential invasion by the Soviet Union. Relations significantly improved in the early 1980s. In 1984,
Deng Xiaoping stated that the People's Liberation Army no longer needed to anticipate an imminent invasion from the Soviet Union. The deaths of Soviet leaders
Leonid Brezhnev (in 1982),
Yuri Andropov (1984), and
Konstantin Chernenko (1985) provided the opportunity for Sino-Soviet "funeral diplomacy" and an improvement in relations. Chinese Foreign Minister
Huang Hua met with Soviet Foreign Affairs Minister
Andrei Gromyko at
Brezhnev's funeral. Chinese Vice Premier and
Politburo member
Wan Li attended Andropov's funeral in a diplomatic move which signaled China's positive view of Andropov and optimism for better relations. Soviet-educated and Russian-speaking Vice Premier
Li Peng attended Chernenko's funeral and met with Soviet leader
Mikhail Gorbachev twice. Gorbachev affirmed to Li that the Soviet Union also wished to improve relations. At the Li–Gorbachev meetings, the two sides began again to refer to each other as "
comrades" and Li congratulated the Soviet Union for its "socialist course". Despite the reconciliation, China made clear that it would continue to develop an independent foreign policy. China's
reform and opening up and the Soviet Union's
perestroika raised similar challenges for both countries. Chinese leader
Deng Xiaoping wanted to reduce tensions with the Soviet Union to facilitate focusing resources on economic development. Gorbachev likewise sought a more peaceful bilateral relationship in order to reduce military expenditures. Intrigued by reform and opening up, Gorbachev told a Chinese magazine, "We take special interest in China's ongoing economic and political reforms. Our two countries are now faced with similar problems. This will open a broad horizon for useful mutual exchange of experiences." The September 1989 withdrawal of Vietnam's forces from Cambodia further reduced Sino-Soviet tension.
Gorbachev visited Beijing in May 1989 for the first summit between the two nations in thirty years. == Relations between the Post-Soviet states and China ==
