Sino-Soviet event background

The Sino-Soviet conflict began from 1927 to 1937 during the agrarian revolution. China's Mao Zedong and others * * * thought that the instructions of the Soviet Union and the Communist International did not conform to China's national conditions of lacking the working class, and decided to mobilize the peasants to carry out the revolution. The "twenty-eight and a half Bolsheviks" representing the Soviet line gradually withdrew from the power center.

After the end of War of Resistance against Japanese Aggression, Stalin of the Soviet Union hoped that the Communist Party of China (CPC) would cooperate with the Kuomintang. 1945 The Soviet Union and the Kuomintang-led National Government signed the Sino-Soviet Treaty of Friendship and Alliance. China * * * never took orders from the Soviet Union. 1949 People's Republic of China (PRC) has been pursuing a "one-sided" foreign policy since its founding, that is, moving closer to the Soviet camp.

1950 China and the Soviet Union signed the Sino-Soviet Treaty of Friendship, Alliance and Mutual Assistance. China and the Soviet Union formed an alliance. The Soviet Union began to provide China with a lot of technical assistance, such as the construction of Wuhan Yangtze River Bridge and other construction projects, and exported various technologies and talents. 1953 After Stalin's death, 1954 Khrushchev visited China, and Lushun, Jiangjun Port, was returned to China. At that time, Mao Zedong was worried about the American attack and asked not to withdraw Soviet troops.

1956, at the 20th Congress of the Soviet Union, Khrushchev criticized Stalin's personal superstition and put forward the "triad route". The post-Soviet Union established diplomatic relations with Yugoslavia criticized by Stalin. Khrushchev's criticism of Stalin, especially the revision of the irreconcilable contradiction between capitalism and socialism in Marxism-Leninism, made the Communist Party of China (CPC) unhappy.

1In April and July of 1958, the Chinese Communist Party asked the Soviet Union to provide the promised nuclear weapons and nuclear submarines. The Soviet Union proposed to build a military long-wave radio station on the territory of China and set up a joint fleet with China in the territorial waters of China in exchange. On the issue of building a long-wave radio station, Mao Zedong thought it involved sovereignty, and proposed that China should contribute half, the Soviet Union should contribute the other half and all the technology.

However, the sovereignty of long-wave radio station belongs to China, which was rejected by the Soviet Union. And the formation of the joint fleet, Mao Zedong thought that the Soviet Union was trying to control China militarily. At that time, China's navy was too weak to share the Soviet coastline even if it formed a joint fleet. Mao Zedong later recalled this incident and said, "In fact, the falling out with the Soviet Union was 1958. They controlled China militarily, but we didn't. "
