China doesn’t have alliances with any one that they would stop doing business to other whichever is it about weapons or something else. Not really that big of a deal unless, they are sending soldiers or ships or planes at least there is no proof of state ordered troops like on the north korean case.

What US did was way worse when agent krasnov (trump) took power he made absolute U-turn and betrayed Ukraine and also humilated Zelenskyi by blaming, Zelenskyi the guilty one for russia’s attack on Ukraine only to spread propaganda to his voters and russia. Also US hasn’t really, send any support after he took office but having personal talks with the invader without involving the attacked side and still does! Or any nato or eu countries too. And lying constantly he even took money from kreml its like its if putin was annouched to secretary leader of nato!
