1. In the 1950s, New China adopted a hostile policy toward the United States. Because the United States did not recognize the legal status of New China and imposed an economic and military blockade on New China because of Chairman Chiang Kai-shek.

2. At that time, the United States protected Taiwan and wanted to use Taiwan as a frontline for Western imperialism to fight against Japan, because the Cold War was beginning to take shape at that time. In June 1950, the Korean War broke out in the United States, and the United States took the opportunity to send troops to Taiwan. On June 27, U.S. President Truman claimed that "the occupation of Taiwan by communist troops will directly threaten the security of the Pacific region" and ordered the Seventh Fleet to station in the Taiwan Strait, blatantly interfering in China's internal affairs with force in the name of "helping to defend" Taiwan. . Two days later, six destroyers and two cruisers of the Seventh Fleet entered the Taiwan Strait and immediately began cruising. The Seventh Fleet's stationing in the Taiwan Strait temporarily saved the Chiang regime from destruction and enabled Chiang Kai-shek to continue to maintain his autocratic dictatorship in Taiwan. It also created a long-term separation pattern between the two sides of the Taiwan Strait and hindered the process of China's reunification.

Secondly, the Chinese volunteers went to fight in North Korea. After the bloody battle of the volunteers, they forced the United Nations forces headed by the United States to sign the "Armistice Agreement."
