You mean besides China financing their military buildup?
Hey wait, we can't be saying that all those Chinese missiles were bot at U.S. factories. Like, their serviceman are certainly not being paid in U.S. dollars. To imagine that the PROC gov't expanded their war dept. using American dollars is (let's be polite here) --OK, simply not believable.
How do you imagine they are getting the wealth to pay for it if not through trade?
Don’t be silly, of course US dollars help their military.
