I'm not sure "financing" their military buildup is the right way to analyze what's happening in China. Do they really have a dependence on U.S./western goods? It seems like almost all their production is domestic besides imports of chips and software (Microsoft, Apple, etc.). I doubt they'll have much trouble replacing those U.S. imports either. And, at least from western reporting, it seems that China has significant coercive control over their people even in their daily lives. If all this is true, then it makes no sense to quantify China's efforts in dollars and to think that somehow the West is financing it. It makes more sense to look at China as a self sufficient economy with a potential labor force of 1.4B and compare it to the U.S., EU, India, etc. which have a similar position and are for now buddies in competition against it.
