If anything, I'd have thought it's likely to go the other way: China gets to play the relatively responsible global citizen that doesn't send in tanks to resolve its territorial claims. Also new potential export markets. I thought Putin was doing the show of power for domestic consumption where he'd embarass the West by actually withdrawing the armies slightly after he promised and it'd all end in a summit with both sides claiming they 'won', but he's gone well beyond that now.
