How about economic sanctions against countries deemed "non-compliant" using whatever measure China wants? China can use their influence in the accord countries to bend other countries to their will, and anyone who doesn't think that they won't try and use it against us is living in a fantasy world.
Interesting thought. Clearly China is our enemy, and will do what they can to diminish our influence.
I wouldn’t consider economic sanctions, by them, or any country they influence, to be a serious threat to the US. We consume far more from the rest of the world than it consumes from us. And what the world does consume from us (technology) can’t be found anywhere else.
Any country who sanctions the US will be slitting their own throat.
Sanctions? Against us? OK.... See if you sanctioning countries can live past next month without the U.S. markets - or any of the other ways we give you money.
I dare ya.
