Japanese evaluate immigrants to the northeast.

Without consulting professional materials, I wrote a little by impression and memory.

The purpose and composition of Japanese immigrants to Northeast China are different from those of Spanish and Portuguese immigrants to the United States in the early days.

The deep-seated reason for Japan's external expansion is Japan's small territory and poor living conditions. After Japan extended its influence to the three northeastern provinces, it immediately began the so-called "Manchuria Colonization Plan" and immigrated to the Northeast on a large scale and in a planned way. Its fundamental purpose is to consolidate its rule in the northeast and attempt to turn the northeast into its permanent territory.

A considerable number of Japanese immigrants in the three northeastern provinces were resettled by the government or forced to emigrate, and a small number were family members of the Kwantung Army and the puppet Manchukuo government. The vast majority of Japanese immigrants are still in the position of ordinary people, and they produce in families.

The early overseas immigrants in Spain, Portugal and other countries were due to adventure plunder or religious spread. The motive force of Spain and Portugal's early colonial expansion was the pursuit of precious metals and rare commodities. Columbus and Magellan, although supported by the state, were not formal troops. Spain's conquest of Inca and Aztec was accomplished by a few careerists with "private armies". Most of the early colonists were big farmers, mine owners and missionaries, belonging to the upper class, oppressing and ruling Indians and black slaves.

Countries like Spain and Portugal have always lacked a planned national migration organization. On the one hand, it is related to regional and cultural differences. Ethnic migration in western Europe is frequent, and people have no tradition of living in one place for a long time. On the other hand, the environment in the western part of the United States is hard, far from being superior to that in Iberia. The migration of ordinary people has not improved much, and the population pressure in Spain and Portugal is not particularly great.
