The US is subsiding a lot of industries. Aviation, agriculture (specially agricultural exports), transportation and energy. They just introduced CHIPSA act to promote US companies chipa production and a lot more. When china does this (which is does) then this is far cry and outright harmful for international trade. Lets get out of comparison between US and China. Smaller countries will be hit hard (even with sanctions) if they try to do something from that.
The point here is that the US, China shouldn't try to prevent other countries from doing what they are doing and forcing them to harm their local economy and open markets under the disguise of free trade.
