My bet is that once Russia is on a black list for everything China is going to keep Russia on a leash. Buy enough from them in yuan to keep them alive, sell to them to get those yuans back, don't make them so rich to be able to rebuild a really worrisome army. And who'll be in the Cremlin will still rule over all of Russia and be rich and happy.

I'd like to hear from someone in Russia to understand if this is a credible endgame.
