Treaty of Taipei
Taiwan was formally incorporated into the Qing dynasty in 1683. After the First Sino-Japanese War, it was ceded by the Qing to the Empire of Japan in perpetuity in 1895. At the end of World War II, it was surrendered by Japan to the Kuomintang (KMT) administration of the Republic of China. After the establishment of the People's Republic of China in 1949, Taiwan and some neighbouring islands continued to be controlled by the Republic of China government. In 1952, the Treaty of Taipei nullified all treaties, conventions and agreements previously concluded between China and Japan before December 9, 1941. Currently, the People's Republic of China (PRC) government considers Taiwan to be a province of China. According to the PRC, it is the sole legitimate government of China, and the government of the Republic of China ceased to hold sovereignty over China when it lost control of the Chinese mainland following the Chinese Civil War. It argues that the PRC assumed sovereignty over the entirety of China in 1949–1950, including Taiwan, although the latter remained under the administration of the Republic of China government.
