The Chinese are going to protect their trade deals with us before they’d ever take a bullet for Fat Boy. I’m sure by now they’re beyond tired off his crap.
The Chinese also know that they need to transition from an export-driven economy to a consumer-driven one. If they’ve already undertaken that transition they might decide the Korea issue differently.
This is post-post communist China. They love the economic benefit of capitalism, but the rise to the top politically is perilous as it’s still a heavily skewed totalian state. So those that make it are pretty adept.
They will be competitive with whatever type of negotiations President Trump throws at them.
Watching President Trump, I wonder if that bru ha ha over moving closer to Taiwan and even as far back as suggesting Japan arm itself with nukes was laying the groundwork for their eventuall meeting.
