Theory of the Undetermined Status of Taiwan

The Theory of the Undetermined Status of Taiwan (Chinese: 台灣地位未定論; pinyin: Táiwān dìwèi wèidìng lùn), also called the Theory of the Undetermined Sovereignty of Taiwan (Chinese: 台灣主權未定論; pinyin: Táiwān zhǔquán wèidìng lùn), is one of the theories which describe the island of Taiwan's present legal status. In 1950, after the outbreak of the Korean War, United States president Harry S. 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 and that "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." This statement of Truman is generally regarded as the origin of the Theory of the Undetermined Status of Taiwan.
