Correct, China's economy would be put back 20+ years...No doubt two weeks after China invades he'll threaten sanctions in their defense just like he did in Ukraine.
That'll teach those commies!
Yes, there would be pain on both sides but China would have it's manufacturing base decimated...
No need for shooting people... China you can invade but expect the price to be unjustifiable...
China saw what the world done to Putin... Xi isn't so stupid, he will sabre rattle but it is not in his interest to get involved in a crap show like that...
