The United States’ moral assistance to China during the Anti-Japanese War. In 1940, China received two loans from the United States, the Yunnan Tin Loan and the Quasi Fund Loan.

On March 7, 1940, the United States allocated US$20 million in loans to China in the name of the Export-Import Bank of China.

On September 13, 1940, after hard lobbying by Chinese Finance Minister Song Ziwen, the United States agreed to provide China with a new loan of US$25 million.

On November 29, 1940, U.S. President Roosevelt instructed Morgenthau to grant China a US$50 million stabilization fund loan within 24 hours, and also asked Jones to provide another US$50 million commercial loan from the Export-Import Bank.

On November 30, 1940, a statement on financial aid to China was issued.

The news spread to China, adding morale and confidence to the struggling Chinese anti-Japanese forces.

In July 1940, the United States completely banned the export of scrap steel to Japan, and the embargo against Japan was extended to all weapons and ammunition, military equipment, aircraft parts, optical instruments, metal processing machinery, and various strategic materials.

In December 1940, U.S. President Roosevelt approved the expansion of the embargo against Japan, which included brass and pure copper that Japan urgently needed to manufacture arms.

In March 1941, the United States passed the Lend-Lease Act, and China was included as a lending country in the Lend-Lease Act.

U.S. President Roosevelt agreed to China's request for assistance.

It was clearly announced that the United States would provide unconditional and comprehensive assistance to the United Kingdom, China and other countries.

U.S. Secretary of State Hull rejected Japan's diplomatic proposal that the United States recognize Japan's exercise of power over Chinese territory and stop aiding China. Instead, he strongly demanded that Japan withdraw its troops from China and declared that this was the basis for U.S.-Japan negotiations.

On April 10, 1941, U.S. President Roosevelt secretly issued an order to allow U.S. reserve officers and retired Army and Navy aviation force personnel to join the American Volunteer Corps.

China purchased 100 American aircraft at a good price.

The UK has the right of first refusal to purchase these aircraft. It is the Americans who have done work for Britain, which is in urgent need of aircraft, so that these aircraft can arrive in China.

On April 15, 1941, U.S. President Roosevelt summoned Chinese Finance Minister Song Ziwen.

Two days later, he officially informed the Nationalist Government that he had approved the first batch of military equipment worth US$45 million to be leased to aid China.

On May 6, 1941, the U.S. government designated Curie as the person in charge of implementing the program to assist China in arms supplies under the Lend-Lease Act.

On May 18, 1941, the first batch of aid supplies worth US$1.1 million, including 300 vehicles, departed New York and headed for China.

On May 25, 1941, the United States once again approved aid to China worth $45.4 million in weapons and ammunition.

On June 9, 1941, the first American support team consisting of 110 pilots, 150 mechanics and other ground medical personnel flew to China.

Later, U.S. President Roosevelt ordered the U.S. training ships Salt Lake City and Northampton to escort the second batch of aid workers heading to China.

On July 23, 1941, Roosevelt went one step further and approved Curie to provide equipment and personnel for a Chinese aviation fleet with 500 aircraft in accordance with Chiang Kai-shek's request.

On July 22, 1941, the United States terminated all negotiations with Japan.

On July 26, 1941, the U.S. government froze Japanese assets in the United States.

On August 1, 1941, the Flying Tigers were officially established.

On August 2, 1941, the U.S. government announced a comprehensive oil embargo against Japan.

At the same time, Britain and the Netherlands also banned the export of copper, jute, pig iron, nickel, cobalt and other materials to Japan, and froze Japanese assets on August 7.

This series of severe measures was unbearable for Japan, especially the oil embargo.

On August 9, 1941, the Japanese military command officially announced: "Stop the plan to use force in the north this year." Give up the plan to attack the Soviet Union.

From August 9 to 14, 1941, Roosevelt and Churchill signed the Atlantic Charter, announcing the concept of world order, and unanimously determined that the purpose of this war was to oppose fascism and defend democracy.

(Fascism, of course, includes Japan.) On September 6, 1941, the Emperor of Japan personally participated in the decision to "resolutely resolve to fight the United States."

On November 7, 1941, after learning that Japan was determined to attack the United States, the United States formulated a memorandum: 1. Not to send troops to assist China; 2. U.S. volunteer troops to assist China should be carried out to the maximum extent; 3. Strengthen assistance to China; 4
