From 1939, the attitude of the United States towards China began to loosen. Initially, the United States provided China with a barter loan, that is, the United States first gave China a sum of money, and China repaid it with some strategic materials (such as tung oil, tungsten ore and tin ore) designated by the United States. These loans are mainly commercial activities, with a total amount of about10.23 billion US dollars, and China must repay the principal and interest. After the outbreak of the Pacific War, the United States gave China a generous loan of more than 500 million dollars. The money has not been returned, but it needs to be subject to financial supervision in the United States, where only materials can be purchased.
In kind, from the outbreak of the Pacific War to the end of the Anti-Japanese War, the United States gave China about $400 million in kind aid, but the United States has the right to distribute these materials. Stilwell is so awesome because he has the right to distribute these materials. These materials come from the lease act and should be returned in theory, but they should not be returned (no country in the world has returned them).
In terms of personnel, the Flying Tigers are well known, and then there are American military advisers.
Technical aspects, including espionage, air force logistics and so on.
If you have to calculate the total, it will be11.200 million dollars.
