|Question||What was the ending date of Japanese sovereignty over Taiwan?|
|Answer||A 1949 CIA report confirms that Taiwan is territory under military occupation, awaiting further disposition in a peace treaty. Looking at the San Francisco Peace Treaty (SFPT), it is clear that the date when Japanese sovereignty over Taiwan ended was April 28, 1952.|
In Chapter 2 of Formosa Betrayed, author George H. Kerr noted that "The immense sweep of global events in mid-summer 1945 obscured one technical point of importance. Japan was surrendering her empire to the Allies and not to China alone. Formosa was Japan's sovereign territory, and sovereignty could not be transferred until a peace treaty could be worked out, agreed upon, and signed."
