It depends on many things. As stated before, English speaking countries get much higher CPMs, because advertisers pay more for ads in the US,Canada,Uk, etc. I would not expect to be able to ever make a decent income in Russia off of YouTube to be honest. The only way you could is if you got a Russian network that sells its own advertisements to Russian companies. YouTube's sales team does not really bother with countries that don't speak english, so they get much lower bids outside of English countries.
