What’s Russia gaining by invading Ukraine?
Why would China be involved in this at all? This war disrupts Chinese non-military takeover of Silk Road territories, where they are dominant economical force already.
The only losers in this play are Russians, where only "brightest" of them think of such crazy scenario, that you are proposing. People in a way do not differ from lemmings - even millions of them can be wrong on their way down from cliff. But, while they are running amok, they have a goal - for that moment.

On one hand it is 'a gas station masquerading as a country', 'Russia doesn't make anything important', or 'has a GDP only the size of Italy', or 'anything outside Moscow or St Petersburg is backward and rural without proper toilets', or another of many other US put-downs about Russia.
Then on the other hand 'Russia can overthrow the US electoral system', 'Trump is Russia's puppet', 'Russia will bring down the US electrical grid', 'Russia can destroy the US by spying everywhere', or today's panic: 'Russia could hit U.S. chip industry by withholding important materials', etc, etc, etc.
Make up your minds. Is Russia a 100 lb. weakling, or is Russia a 500 lb. bully? If it's a weakling why so frightened of it? If it's a bully, how can the the US be 'Number One'?
Russia is also militarily powerful and with enough resources and cleverness to take everyone else down the drain with them.
This is a particularly bad combination-- being successful or weak takes away much of your menace to your neighbors... being failed and strong is the scariest combo.
It's a 100 lb. bully, who can nevertheless go as far as a 500 lb. one if not stopped.
