I can tell, it did in fact seem to put a lot of pressure on China and they weren't too stodgy to admit they were getting way too good of a bargain at our expense.
One thing they still need to clean up is the insanely low shipping costs for small packages - somehow you can ship something across the ocean and through ports on both sides for about 1/5 the price of shipping within the US due to some really weird postage loophole that makes USPS subsidize imported packages, putting US businesses in a tough spot.
Looks things are already getting cleaned up. What a joke it took this long though. Not a Trump fan generally, but him getting us out of these totally unfair trade agreements is long overdue.
