If Putin told Xi during the Olympics of the impending invasion, then why NOW (5 days into invasion) that China successfully evacuate it's first people
He wasn't told. At most, Putin probably hinted something but Xi probably didn't believe that a leader of a big power like Russia would do such a thing.did Putin only vaguely hint about it?
I bet that Xi knew something would happen (no war though) and he just told him that whatever he wanted to do, do it after the Olympics end.
I don't believe for a minute that Putin told Xi:
"Bro I am getting Ukraine"
