Why there are 130 ethnic groups in Kazakstan and only 56 ethnic groups in Chinese mainland? Kazakhstan is 65.438+350 million 50 million less than the total population of the mainland.

Originally, Kazakhstan was dominated by turkic peoples, but after it was incorporated into Russian territory, ethnic groups moved in, with the largest number of Russians. Especially during the Soviet Union, a large number of immigrants were placed in Kazakhstan, and important facilities such as refugees and factories moved eastward during World War II, resulting in a large ethnic population in Kazakhstan, even hundreds of thousands of Koreans. It is not surprising that after Japan invaded the Korean peninsula, a large number of Koreans took refuge in the Soviet Union and were placed in Central Asian countries by Stalin.
