Then cite from the Russian civil code or from Russian precedents the relevent passages that show that Russian law acknowledges unregistered trademarks.
Not needed. Unregistered trademarks are legal in the US and EU countries so if they want to travel to these nations then they should respect our trademark.
ICANN has separate rules that govern domain names; they are very highly supportive of protecting all trademarks (even more so than regular trademark law is). And registration in the appropriate jurisdiction will be sought before any legal action is taken so your point is moot.
