There are not many Sino-Russian intermarriages in China because there are big differences in culture and social systems between China and Russia.
According to data from the Ministry of Civil Affairs of China, the number of Sino-Russian intermarriages was 35 in 2015, 61 in 2016, 115 in 2017, and 119 in 2018.
Sino-Russian intermarriage is a niche group in China, but this group plays an important role in Chinese society.
