The thread title is wishful one-way thinking.
All China needs to do is stop buying US treasury and that will wreck the US and world economy. Much of the China to US trade surplus has been used to buy US treasury, essentially financing the US government and consumers.
With the trade surplus gone, the cheap financing is gone with it. Just look at how the market did upon Fed’s talk of raising interest rate.
This can turn out to be a black swan shock.
You understood nothing, Right? lol! go back to college a learn about debt.
