Time to take off pink sunglasses, which is the major real powerful country .... not US, but by all measures China... What do you think will happen when US goes into a trade war with the most economic powerful country in the world....?
I am no expert at all on this topic but I reckon that China will not suffer so much, but US will..... I guess people in the US will start losing their jobs over this....
An example, what will happen with Tesla's market share when this war starts .... and Chinese auto makers are getting fully up to speed... well, also Audi, BMW, VW, Opel Mercedes has a fully electric lineup... how many people in Tesla will lose their jobs because of Trump?
(This is pretty old but you see the point)
China's manufacturing output overtook that of the U.S. almost a decade ago. Its exports are more than a third larger as well...
Have a look at this:
