The Japanese puppet state of Mengjiang is formed in northern China.
Mengjiang (Mengkiang), also known in English as Mongol Border Land or the Mengjiang United Autonomous Government, was an autonomous area in Inner Mongolia, formed in 1939 as a puppet state of the Empire of Japan, then from 1940 being under the nominal sovereignty of the Reorganized National Government of the Republic of China (which was itself also a puppet state). It consisted of the previously Chinese provinces of Chahar and Suiyuan, corresponding to the central part of modern Inner Mongolia. It has also been called Mongukuo or Mengguguo (or Mengkukuo; Chinese: 蒙古國) (in analogy to Manchukuo, another Japanese puppet state in Manchuria). The capital was Kalgan, from where it was under the nominal rule of Mongol nobleman Demchugdongrub. The territory returned to Chinese control after the defeat of the Japanese Empire in 1945.
