 The government of the Republic of China, which ruled mainland China from 1912 until 1949 and now controls Taiwan, had a cabinet-level Mongolian and Tibetan Affairs Commission in charge of the administration of Tibet and Mongolia regions from 1912.The commission retained its cabinet level status after 1949, but no longer executes that function.On 10May 1943, Chiang Kai-shek asserted that "Tibet is part of Chinese territory... No foreign nation is allowed to interfere in our domestic affairs".
