China has nearly 20 times the amount of the US reserves!

Answer 1

No, because when China trades with us they send us real goods, such as plastic toys and clothing, and other consumer goods. And what do they get in return?

Green paper with dead U.S. presidents printed on it. There's only one place they can spend that.
