Most people would stay in their countries in both countries most of the time.
and it is really stupid question. You constantly create shit for Russia and then come and say "See Russia is a bad country!"
When in reality it is you who is a bad country because you are actively shit everywhere, that's is how you keep appearance of less shit inside your own country.
It does not work anymore. You can't shit in Russia and you especially can't shit in China.
I have crossed a lot of borders in times long ago. It is very, very obvious what borders are meant to keep people out and what borders are meant to keep people in. First world borders are screening for illegal immigrants, you look first world, they don't look at you except for agricultural reasons. (Nations such as the US and Australia are strict on things like food, we usually get sent to agricultural inspection, but they run the bags through the x-ray and only look at the bags containing organics of reasonable density. This is entirely different from the strictness of immigration control. Expect such things in any nation without neighbors with a similar climate.) Third world, they'll be looking at details, but with an eye to finding some deficiency to use to get a bribe out of you. Second world--much more document inspection, much more luggage inspection.
