What was the basic policy of the United States towards China in the early postwar period?

After World War II, the basic policy of the United States toward China was to help Chiang Kai-shek fight * *, trying to establish a pro-American regime in Chinese mainland and help Chiang Kai-shek militarily. This basic policy continued until the Kuomintang clique retreated to Taiwan Province Province.

With the loss of control of the National Government on the mainland and the establishment of People's Republic of China (PRC), the US policy toward China was adjusted for the first time, that is, the containment strategy of military threat to Chinese mainland, political strike, diplomatic isolation and economic blockade was adopted. This strategy lasted for twenty years.

In the late 1960s and early 1970s, the United States readjusted its China strategy again. At that time, the breakdown of Sino-Soviet relations was a foregone conclusion, Chinese mainland's political influence was increasing day by day, and the United States was unable to cope with the aggressive offensive of the Soviet Union, so it was mired in the Vietnam War and had to make strategic contraction and adjustment. Represented by President Nixon's visit to China and the restoration of People's Republic of China (PRC)'s lawful seat in the United Nations, Sino-US relations thawed and developed rapidly. United States Lianhua's strategic decision to resist the Soviet Union. This strategy reached its peak in 1979 after the formal establishment of diplomatic relations between China and the United States.

After Reagan came to power in the early 1980s, American policy towards China was adjusted, showing two sides. On the one hand, he tried to win over China and continue to maintain Lianhua's anti-Soviet stance; On the other hand, it tries its best to develop relations with Taiwan Province Province. Sino-US relations suffered a great impact in the early 1980s, with a great retrogression, and then gradually eased. However, in 1989, the United States imposed sanctions on China, and Sino-US relations fell to the bottom.

After the end of the Cold War, the United States adjusted its China policy and basically adopted the strategy of "contact plus prevention", which has continued to this day. However, in different historical periods, the emphasis is different, sometimes focusing on contact and sometimes focusing on prevention. Now the definition of Chinese mainland in the United States is "cooperator+competitor".
