When did Chinese Communists occupy Inner Mongolia?
At the end of the W.W.II, Soviet-Mongolian joint army entered Inner Mongolia, in order to expel the Japanese army. After the war, despite the all 51 banners(county) of Inner Mongolia expressed their will to be independent, Joseph Stalin handed Inner Mongolia over to China according to the Yalta treaty. A few large cities remained in the control of Kuomintang (KMT) and the vast rural area of Inner Mongolia fell into Mao s Communist army after the Soviet-Mongolian army s withdrawal from Inner Mongolia. On May 01, 1947, the Chinese government declared the establishment of the Inner Mongolian Autonomous Region, after the PLA took control of the entire Inner Mongolia.
