Does anyone know the reason for the bitterness between China and the former Soviet Union at that tim

China's early relations with the Soviet Union were based on ideological agreement. However, with the formation of the Cold War pattern between the United States and the Soviet Union, the relationship between China, the United States and the Soviet Union was complicated.

The collapse of the Soviet Union also had a good and bad impact on China. On the bright side, before the collapse of the Soviet Union, China and the Soviet Union had a hostile relationship (although relations eased after Gorbachev came to power), and the collapse of the Soviet Union meant the end of Sino-Soviet hostility and the end of Sino-Soviet confrontation. China's external threat has been greatly reduced, and the Sino-Vietnamese border standoff has been resolved.

Detailed explanation. China's ability to gradually disarm after the 90s has a lot to do with the reduction of military requirements on the Sino-Soviet border. On the bad side, the Soviet Union no longer exists, and the Sino-US contradiction will rise to the first contradiction, the Sino-US honeymoon period will end, and the United States will also resume the embargo on China.

Relations between China and the United States are about to resume hostility again. In addition, the collapse of communist beliefs caused by the collapse of the Soviet Union caused the Chinese people to enter a spiritual confusion for about 10 years, and the idea of blindly worshiping the West spread on a large scale, and it was not until the 21st century that it began to decrease.

The Sino-Soviet war was a gradual and complex process.

The Sino-Soviet conflict germinated during the agrarian revolution of the 1930s. Mao Zedong of the Chinese Communist Party and some other leaders decided to mobilize the peasants for a revolution because the instructions of the Soviet Union and the Communist International were not in line with the conditions of China, which lacked the working class. The "twenty-eight Bolsheviks", representing the Soviet line, gradually withdrew from the centers of power.

After the end of the War of Resistance Against Japan, the Soviet Union's Si Da Lin hoped that the Chinese Communist Party and the Kuomintang would cooperate. In 1945, the Soviet Union and the Kuomintang-dominated Nationalist Government signed the Sino-Soviet Treaty of Friendship and Alliance. The Communist Party of China has never accepted the instructions of the Soviet Union.

After the establishment of the People's Republic of China in 1949, it has always pursued a "one-sided" foreign policy, that is, moving closer to the Soviet bloc. In 1950, China and the Soviet Union signed the Sino-Soviet Treaty of Friendship, Alliance and Mutual Assistance. The Soviet Union began to provide a large amount of technical assistance to China, such as aiding the construction of the Wuhan Yangtze River Bridge and other construction projects, and exported various technologies and talents.

After the death of Si Da Lin in 1953, Khrushchev visited China in 1954 and returned the military port of Lushun to China. In 1956, at the 20th Congress of the Communist Party of the Soviet Union, Khrushchev criticized the personal misconception of Szelin and put forward the "three-harmony line." Later, the Soviet Union established diplomatic relations with Tito's Yugoslavia, which had been criticized by Sito.

Khrushchev's critique of the Szorrin and especially his revision of the irreconcilable conflict between capitalism and socialism in Marxism-Leninism displeased the CCP.

In April and July 1958, the Communist Party of China demanded that the Soviet Union provide the promised nuclear weapons and submarines, and the Soviet Union offered to build long-wave radio stations for military use on Chinese territory in exchange for the formation of a joint fleet with China in China's territorial waters. On the issue of building a long-wave radio station, Mao Zedong held that this involved the issue of sovereignty, and proposed that China should contribute half of the funds, and the Soviet Union would contribute the other half of the funds and all the technology, but the ownership of the long-wave radio station belonged to China, which was rejected by the Soviet Union. As for the formation of the Combined Fleet, Mao Zedong believed that the Soviet Union was attempting to control China militarily. China's navy was so weak that it could not share the Soviet coastline even if it formed a combined fleet.

Mao Zedong later recalled this incident: "In fact, the fall out with the Soviet Union was in 1958, and they controlled China militarily, and we did not do it. ”
