The Japanese bombing of Pearl Harbor brought the United States into the war and merged the Sino-Japanese War into World War II as China declared war on Japan, Germany, and Italy. American and British loans and supplies, the establishment of military air bases in China, and the aid of an increasing number of U.S. and British advisers helped relieve China as Japan diverted armies elsewhere. Nevertheless, China's military position continued to deteriorate until Apr., 1945. In May the Chinese launched a successful offensive at Zhijiang (Chihkiang) that lasted until Japanese capitulation on Aug. 14. The Japanese troops in China formally surrendered Sept. 9, 1945. By the provisions of the Cairo Declaration, Manchuria, Taiwan, and the Pescadores were restored to China.
