Step-by-step explanation:
The areas of China that have seen the largest ethnic migration from the 1960s to 2020 include the core industrial cities in China Proper, Southeast Asia, and the United States.
In China Proper, rural-to-urban migration has been one of the largest in human history, with migrants moving from the periphery to the core industrial cities. This urbanization and industrial activity have attracted a significant number of migrants.
In Southeast Asia, there is a significant population of overseas Chinese, many of whom migrated during the last Chinese dynasties and during the colonial era. European colonial powers contributed to this migration pattern.
In the United States, large-scale Asian immigration primarily occurred from Korea and Vietnam during the second half of the twentieth century. Korean immigration has been gradual, while Vietnamese immigration mainly took place after 1975, with many Vietnamese immigrants coming as political refugees.
