Theory of the Undetermined Status of Taiwan


The Theory of the Undetermined Status of Taiwan, also called the Theory of the Undetermined Sovereignty of Taiwan, is one of the theories which describe the island of Taiwan's present legal status.
The theory originated from United States President Harry S. Truman's statement on 27 June 1950, regarding the Korean War, which had broken out two days earlier. In his statement, Truman said that it would be a direct threat to the United States' security in the western Pacific area if the communist forces occupied Taiwan, so he ordered the 7th Fleet to enter the Taiwan Strait to prevent any attack on the island. Truman stated: "The determination of the future status of Formosa must await the restoration of security in the Pacific, a peace settlement with Japan, or consideration by the United Nations." Because of the statement, the Theory of the Undetermined Status of Taiwan came into existence.
Although Japan concluded the Treaty of San Francisco with the Allied Powers after World War II in 1951, in the treaty it merely "renounced" all right, title and claim to Taiwan and the Pescadores without explicitly stating the sovereignty status of the two territories. Therefore, the Theory of the Undetermined Status of Taiwan is still supported by some politicians and jurists to this day.
Supporters of the theory include, but are not limited to, supporters of the Taiwan independence movement. They believe that Taiwan's status should be determined by Taiwanese people through self-determination.
