Japanese troops entering Shenyang, China during Mukden Incident.With little resistance, Japan invaded and conquered Manchuria in 1931. Japan claimed that this invasion was a liberation of the Manchus from the Chinese, although the majority of the population were Han Chinese. Japan then established a puppet regime called Manchukuo, and installed the former Emperor of China, Puyi, as the official head of state. Jehol, a Chinese territory bordering Manchuria, was also taken in 1933. This puppet regime had to carry on a protracted pacification campaign against the Anti-Japanese Volunteer Armies in Manchuria. In 1936, Japan created a similar Mongolian puppet state in Inner Mongolia named Mengjiang (Chinese: ??) which was again predominantly Chinese. Japanese, Koreans and Taiwanese were banned to immigrate North America and British Commonwealth. Manchukuo opened the immigration of Asians. Then they could emigrat in Manchria, Japanese population grew 850,000.
