“There’s a very substantial chance ... it won’t work out. And that’s OK,” Trump told reporters. “That doesn’t mean it won’t work out over a period of time. But it may not work out for June 12. But there is a good chance that we’ll have the meeting.”I'll translate, Rocket Man is trying to negotiate the unnegotiable - removing all nukes, nuke research, anything nuke an verifiable. Trump ain't doing this for show, so he'' ask China if they want more nukes in S. Korea AND conflict in N. Korea, OR do they want to tell liddle rocket man what he better do.
It is true that the real negotiation is going on between Trump and Xi. Kim Jong-un is just a pawn.
