China would have a hard time economically without being able to sell to the US. But it's been developing markets and economies in Rest of World, especially Africa. And its internal market is huge.

Turns out offshoring was one of the most self-harmingly stupid decisions in US economic history.

Still - at least it prevented worker unionisation. So that was such a win for corporate America.
