What bad things did the Japanese colonial development group do in China?

Manchuria Pioneering Group is the most typical colonial policy pursued by Japanese imperialism in northeast China during the war of aggression against China. After the September 18th Incident, Japan helped Puyi become a puppet emperor, established a puppet Manchukuo, and turned northeast China into a Japanese colony. The establishment of Manchuria Development Group was a colonial policy that Japanese militarism moved to the northeast of China in a planned way.

The original meaning of "colony" is to move its nationals out of their native land, establish the same social system there as the home country, and maintain close ties with the home country politically, economically and culturally to safeguard the interests of the home country. If conditions are ripe, it will be included in the national territory. The territory of ancient Greek city-states was very small. After the population reached a certain level, they often went abroad to explore such colonies. After the formation of the concept of modern national sovereignty, with the increasingly clear boundaries between countries, the concept of colony has also undergone major changes, especially the sovereignty of a country is completely controlled by the invaders. It is called colonialism to advocate and carry out aggression against other countries to control the territory and administrative jurisdiction of other countries as a national policy. Before the end of the Second World War, colonialism and imperialism were often twin brothers, and they went hand in hand. With the rise of modern capitalism, colonial powers sent officials, troops, businessmen and capitalists to the colonies for trade and investment, and their families often accompanied them to live and multiply in the local area. Although it is also a kind of overseas colonization, immigration to colonies is not a systematic national policy. In modern colonial history, Britain did it in Australia and Japan did it in Asia.

People in Northeast China are the biggest victims of Japanese colonial policy. Japan Manchuria Development Group is a paramilitary agricultural immigrant group. At first, it mobilized soldiers in the countryside, and later it developed into a strong farmer. After they arrived in the northeast of China in an organized way, they completely deprived the local China farmers of their land, homes and woodlands, which caused a serious survival crisis. The land reclamation activities of Manchuria Pioneering Group served Japan's strategy of permanently occupying the northeast of China. It was the nearest and most reliable supply base of the Japanese Kwantung Army, the supply base of grain and strategic materials, and the basic supporter of Japan's colonial rule in the northeast of China. In order to meet the needs of developing young men's sexual life and getting married, Japan also launched the so-called "Marry a Mainland Man" campaign to mobilize Japanese women to come to the Northeast and get married with members of the pioneering group, so as to thrive in China from generation to generation. By 1945, the total number of Japanese immigrants in Manchuria Development Group was estimated to reach more than 300,000. If it weren't for Japan's defeat and surrender, the natural reproduction of these 300 thousand people would be an amazing number in 20 or 30 years.

With the Kwantung Army constantly replenishing troops from the Manchuria Development Group, the young and middle-aged people of the Development Group are decreasing day by day. After the war, the defeated Japanese army retreated to the mainland in an emergency, leaving behind a large number of women and children. These people have no food and clothes, and they are homeless. Some of them have returned to their own countries, while others have been adopted, married and even given birth to offspring by local China people.

The Japanese who were married and adopted by the Japanese were no longer members of the pioneering group, but refugees who stayed in China after Japan's defeat. In their long life, they have forged friendship and affection with the Japanese people and become a bridge to communicate the friendly exchanges between the Chinese and Japanese people. Over the past 60 years, most of these refugees who stayed in China have died. After the normalization of diplomatic relations between China and Japan, relatives and descendants of the Japanese went to the northeast to look for these members of the pioneering group who died and stayed in the northeast and their families. The Japanese government and people have provided all kinds of help and clues out of humanitarianism, which is completely correct. However, because of this relationship, founder county erected a monument for the dead of the Manchuria Pioneering Group, completely ignoring the essence of the matter and confusing the Japanese as refugees with the Japanese as colonists. This is a serious political mistake.
