If Trump was really going to focus on China in a constructive manner, he wouldn’t have gone off and pissed off all of our allies first. Our allies now are just as likely now to form trade agreements with China as they are with the USA, since we now appear just as bad to them as China (even worse, we don’t have much to offer compared to China). As it stands now, China couldn’t have asked for a better situation of American just deciding to go off on everyone at once.
Even Canada is now looking seriously at making a trade agreement with China than with the USA, which was unthinkable just 3 months ago.
