The difference between immigration and colonization

Colonization refers to the migration of powerful countries to the areas they conquered. Now it means that capitalist countries expand their economic and political power to underdeveloped countries or regions and plunder and enslave local people, which is colonialism.

Immigrants generally refer to people who have moved to other places. At present, it mainly refers to those who have moved to other places or abroad because of personal needs, and those who need to relocate or resettle for production because of the construction of reservoirs and power stations by the state.
