From Cairo to Taipei
In November 1943, the leaders of China, the United States, and Great Britain reached a consensus at the Cairo Conference, declaring that "all territories Japan has stolen from the Chinese, such as Manchuria, Formosa, and the Pescadores, shall be restored to the Republic of China." Although not a formal treaty, this declaration became the political foundation for post-war territorial rearrangement in East Asia.

After Japan announced its surrender on August 15, 1945, Supreme Allied Commander MacArthur issued General Order No. 1, designating Chiang Kai-shek to accept the surrender of Japanese forces in Taiwan on behalf of the Allies. On October 25 of the same year, Chen Yi presided over the surrender ceremony at Taipei Public Hall, marking the beginning of ROC rule over Taiwan. However, whether this "acceptance of surrender" constituted a transfer of sovereignty or merely military occupation remains contested to this day.
This volume focuses on key diplomatic documents and international conference records from 1943 to 1945, revealing how Taiwan's post-war fate was determined amid great power politics. From the Cairo Declaration and the Potsdam Proclamation to the MacArthur Memorandum, each document shaped the future trajectory of millions of Taiwanese people.
For the Chinese delegation that flew into Cairo in November 1943, Taiwan was one of the things the trip was meant to bring home. Chiang Kai-shek attended with Soong Mei-ling and Wang Chung-hui, secretary-general of the Supreme National Defense Council, and the diaries kept by that party record a process of drafting word by word: the Chinese side insisted that "Taiwan and the Pescadores" be named in the document rather than folded into vague talk of a postwar settlement. The Cairo Declaration, released on December 1, stated that the territories Japan had stolen from China, "such as Manchuria, Formosa, and the Pescadores, shall be restored to the Republic of China"; Article 8 of the Potsdam Proclamation of July 26, 1945 confirmed that the Cairo terms would be carried out. As Chungking and then Nanking understood it, the legal question was settled there. What remained was the mechanics of the handover. General Order No. 1, issued by the Supreme Commander for the Allied Powers on September 2, 1945, designated Chiang Kai-shek to receive the surrender of Japanese forces in Taiwan, the Pescadores, and the China theater; on October 25 Chen Yi presided over the surrender ceremony at the Taipei Public Hall, and that same day the Administrative Executive Office proclaimed Taiwan's retrocession, a date kept as a holiday every year thereafter. For this government, October 25 was not the beginning of an occupation but the completion of a return — which is why every later claim that Taiwan's status was "undetermined" would sound to it not merely like a legal argument but like a denial of its standing as a victor.

General Order No. 1 issued by MacArthur designated Chiang Kai-shek to accept the surrender of Japanese forces in Taiwan on behalf of the Allies. This memorandum became one of the core documents in the dispute over Taiwan's post-war political status.
