Russia is supplying gas, oil, timber and coal to EU. In return Russia gets automobiles and other manufactured products from EU.
So if EU were to impose sanctions (which I really doubt they will do in any meaningful way) they will come out as losers.
Russia can sell oil and gas to Asia. (China, Japan and S.Korea are very hungry for Russia energy and resources). Also Asia will love to supply more manufactured products to Russia.
On top the trade is mostly carried in local currencies (so free of dollar hegemony) which is an added bonus.
Apart Russia can make life a lot more difficult for NATO in Afghanistan, Iran, Syria and a host of other countries. So I don't see any real sanctions being imposed on Russia. It's all talk and Putin knows it.
