The specific situation is as follows: compiled based on Internet materials

1. Before 1942, the United States provided a loan of US$170 million to China. During this period, the Roosevelt administration was extremely cautious in aiding China. The minimum goal of its aid to China was to prevent China from collapsing in its war of resistance, and the maximum goal was not to cause Japan to take retaliatory actions against the United States.

2. Around the outbreak of the Pacific War, the United States really began to assist China on a large scale. Assistance 1: Two loans*** 670 million U.S. dollars Assistance 2: A large amount of military supplies, including huge "Lease" aid and "Hump Airlift" Assistance 3: Personnel coming to China to participate in the war, including the "Flying Tigers" and the US Fourteenth Air Force The United States used assistance to successfully pin the main force of the Japanese Army to the Chinese battlefield, buying time to resolve the European war first.

3. On August 15, 1945, Japan announced its surrender, ending World War II. On the 21st, Truman officially announced the suspension of the Lend-Lease Act, but the lease to China continued until 1947.

In general, China’s assistance from foreign countries during the Anti-Japanese War was quite limited, totaling only about 1.1 billion U.S. dollars. Fighting against a large number of enemies with extremely limited equipment and supplies was a situation unprecedented in any theater during World War II. At the same time, as a weak and disunified country, it is difficult for China to find a stable ally, and it is difficult for other countries to regard China as a reliable partner. This has made China's experience in seeking foreign aid and cooperation fraught with hardships.
