Why are China people called Han nationality in Russian?

The ethnic division in Russia is rather strange, with 194 ethnic groups in 2002 and 304 ethnic groups in 20 10.

There is no so-called "Han nationality" among these ethnic groups. The nationality of China people living in China is written as китайцы, which means "people" (not all Han people are included here, but their ancestors or I immigrated from China. Of course, if someone emphasizes that he is another nation, he will not be classified as this nation.

I know a китайцы, that is, "China people". Their grandfather's generation immigrated from Sichuan, China via Xinjiang. According to their own statement, they are Qiang people, but now his son has emigrated back to China, but the nation has become "Han".

In 2002, the population of China was 34,577, ranking 56th.

In 20 10, the number of people in China was 28,943, ranking 6 1.

The former Soviet Union's "China people" (ethnic Chinese) mainly lived in Central Asia (during Khrushchev's exclusion from China, everyone moved to Central Asia and was strictly controlled), while the Russian Federation's "China people" (ethnic Chinese) mainly lived in Khabarovsk Krai, Moscow, Primorsky Krai, Irkutsk, krasnoyarskiy kray and other places.
