Its not a total free-riding though, is it?The current position of Chinese economy right now is I think free-riding the global mass stimulus. As long as others keep the stimulus flows, China will be in a good position. They don't have to share the systemic risk as well.
China is basically importing inflation right now, plus it is being paid by monopoly money for hard physical goods.
The one who is free-riding here is the US which has started its printing press, exporting inflation to the rest of the world (mainly China), and then paying for physical good with toilet paper money.
The FED can just insert another 0 to the printing press and China is still forced to accept the currency
