Long live Sino-Soviet friendship. What is the historical period of the two great men?

The Sino-Soviet Treaty of Friendship, Alliance and Mutual Assistance signed by People's Republic of China (PRC) and the Soviet Socialist Union (USSR) in February 1950 came into effect on April 1 1 of the same year, with a validity period of 30 years. The treaty was signed in the Kremlin by the people of China, China's Prime Minister and Foreign Minister Zhou Enlai and Soviet Foreign Minister Vischinski.

The signing of the Sino-Soviet Treaty of Friendship, Alliance and Mutual Assistance, to a certain extent, provided a favorable external environment for the newly born China, promoted the development of Sino-Soviet relations in a benign direction during the honeymoon period, and had a positive impact on the establishment of a permanent and unbreakable friendship between the two countries. 1On April 3rd, 979, the China government announced that the Sino-Soviet friendship treaty signed in 1950 would expire in one year. China will not continue to extend this treaty with the Soviet Union. It was finally abolished in 1980. -Common sense politics.
