1. this seems to be based on misconceptions about how the chinese economy works 2. why haven't they done it yet? is the implication that they will wait until they're dominant in some x number of industries worldwide and then... raise prices?

p.s. how would such "subsidization" work on a such a scale? if you think the EVs, PV panels, etc are cheap because the govt like, just covers the loss on every sale(?) where do they get all that surplus finance to cover labour and resources?

have you considered 'subsidies' can be used for accelerating R&D for national interest rather than some monopolistic plot
