I don’t think China want this either. Seeing the mess this is for Russia I expect China are having doubts about fighting Taiwan.It wouldn't happen (they'll still have China etc) but just imagine (and this wouldn't happen either) if every "Western-Culture" country banned/blocked everything Russian, I mean from little things like every Russian sports team/sports-person banned from every competition or every "international" event is removed from being hosted in Russia, to huge things like every airline/shipline/trainline etc all just stopped going to Russia etc. I think Russia would quickly look inward at a way of solving their problems.
One thing I'm surprised hasn't happened so far inside Russia is the the "unfiltered" internet is still working. I think having so much internet access nowadays makes "pulling the wool" over your countrymen's eyes (or hiding obvious dissent) far harder to do. It'll be interesting to see if there's much change in everyday Russians reactions once the body-bags start coming home?
