Manchuria

In 1931, Japan invaded and conquered Northeast China (Manchuria) with little resistance. Japan claimed that this invasion was a liberation of the local Manchus from the Chinese, although the majority of the population were Han Chinese as a result of the large scale settlement of Chinese in Manchuria in the 19th century. Japan then established a puppet state called Manchukuo (Chinese: 滿洲國), and installed the last Manchu Emperor of China, Puyi, as the official head of state. Rehe, a Chinese territory bordering Manchukuo, was later 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: 蒙疆), which was also predominantly Chinese as a result of recent Han immigration to the area. At that time, East Asians were banned from immigration to North America and Australia, but the newly established Manchukuo was open to immigration of Asians. Japan had an emigration plan to encourage colonization; the Japanese population in Manchuria subsequently grew to 850,000. With rich natural resources and labor force in Manchuria, army-owned corporations turned Manchuria into a solid material support machine of the Japanese Army.
