Generally he doesn't see any consequences for things that would have been compared beyond the pale for a CEO a few years ago but this is the first time he's done something that might offend Xi. Not a great idea for a huge China suckup heavily dependent on good CCP relations
I think that's ameliorated by also mocking other world leaders -- and also himself as a kind of chubby Iron Man. Leaving Xi out might have been a bigger insult.
