Last year, our trade deficit with China, was a new all-time record high.

Besides the U.S. buying a lot of Chinese products , the Chinese government actively plays with its currency to give itself financial advantage over the dollar.
All manufacturing and trade is controlled by the Chinese government.
Any trade agreement is only good as long as all players play fair, with mutual respect... and the Chinese believe in " China First" to the detriment of others.
No wonder they fear anyone whom they disagree with , especially a candidate who states : " America First " !
