And look at how Trump responds,  with "US-China trade & money" again.  Trump thinks that only money counts.  Well, money is important but it's not the only thing that motivates people & nations.  Power, the ability to threaten you neighbors & enemies with destruction is important as well.  Kimi has already killed a  reported 350-some of his own people, why should a few hundreds of thousands of Americans bother him.   And why should China help?  Trump's understanding of the power dynamic is all wrong.  Besides you can only use the trade threat so many times and he's already used it once before for Taiwan.
