All I know about Russians and Chinese is, that China economy is bigger than Russia’s by order of magnitude.
Chinese business people and highly educated workers are prevalent in every country with substantial economy. Russians? They are good at ballet, spying, and how many older Russian women have you observed, who are not fat? Most Chinese women age more gracefully.
If Chinese women age so “gracefully” why are Chinese men marrying Russians? No doubt they’re buying VISA’s in order to get into the country and hedge their bets. Russian women are always looking for wealthier foreign men, but I suspect the Chinese government encourages this in order to get more people into Russia in order to “influence things”.
