Is China Going to Help Russia?

There was a lot of talk before the war, and even an initial in the days of the war, that china is going to come to russia's rescue. If they attempted to do something like this, they would be labelled traitors. And we know that traitor for putting regime and putin personally, is a big thing. So they should be definitely fearful for their for their life in the wests. But am kind of dubious that the russian government would not retaliate against most of these oligarchs whose fortunes are still within russia.
