? Um, we do all the time and make trade deals all the time with other countries that can produce what we want to buy and undercut China. Are you seriously, just unaware of this?
It doesn't mean that we won't do business with China and for some incomprehensible reason, you keep prattling on about the USA cutting off trade with China
