I don’t know about easy but a bunch of other solutions would do the trick..
I think one of the main things we should do is cut them off from Western Capital Markets, especially Wall Street...
No Chinese companies listed in the NYSE, no Chinese companies allowed to issue credit thru Wall Street, etc...
For their economy to operate, they need US Dollars, cut off the Dollars and kill their economy....like you said that would be easy and really effective.
In a word, tariff.
If you want to have food, drugs or any machinery, I’d hold off of that. American’s have no idea how dependent we are on China, although there is a slow awakening. Frankly it would take more than a decade for the US to be able to function without China.
