Cairo Declaration
The United States entered the War in December 1941. Most military attacks against Japanese installations and Japanese troops in Taiwan were conducted by United States military forces. At the Cairo Conference, the U.S., United Kingdom, and the ROC agreed that Taiwan was to be restored to the ROC after the war. This agreement was enunciated in the Cairo Declaration and the Potsdam Declaration, which outlined the terms of Japanese surrender, specified that the terms of the Cairo Declaration shall be carried out.
