They banned Russia from FIFA, UEFA, IOC, etc.
For so many of Chinese viewers here, this is a little preview for the things to come if China decides to move on Taiwan. Don't think for a second that Europe won't cut off trade with you. They will all fall behind the US and marshall agaisnt China and use the same tactics they doing to Russia but even greater extent. South Korea, maybe Philipines as well will join in. So-called neutral countries will all unite against you like they are doing to Russia.
When that moment, China will be glad that Russia might have their back. I see a lot naive comments from so many here deciding whether China should support Russia or not. Well China has no strong allies and if it leaves Russia hanging in this moment, Russia will return the favor in the future.
US alliances includes the whole of Europe (Italy, Greece, etc), Japan, South Korea, Philippines, Australia, and maybe India, and many more countries. And when the chips fall, they will all fall behind the US.
Beijing should play their cards right and not squander this opportunity with Moscow. They should actively provide a life-line for Russia in their dire moment and Russia will return the favor in the future.
Unless China wants to pretend that Europe is still up for play.
