How does this “shut out” China? Will the US ban Chinese goods from entering other countries? Probably not. Even if on the off chance this were to happen, it would be a declaration of war. Also, don’t delude yourself thinking that China is still export driven. China is in fact the world’s largest market. If any country were to do what you have proposed here, they would in return be blocked from the world’s largest market, which is gradually happening to us products like LNG and soy bean.
I know you want to feel good about your country, but this is just deluding yourself.
