"in far eastern city of Yakutsk where i was born situation of course was different, no discrimination at all. in fact after period of trouble in 1990 many ethnic russians and other europeans left this place and much more ethnic minorities moved in. so it became thoroughly asian city where local speech is more often spoken than russian."

And this is what I'd assumed (I indeed have an ethnic Russian friend who left that area around that time.)  But you still felt uncomfortable there?
