President Donald Trump on Sunday issued new threats against America’s trade partners, calling for them to remove trade barriers and tariffs, or face the consequences.

“The United States is insisting that all countries that have placed artificial Trade Barriers and Tariffs on goods going into their country, remove those Barriers & Tariffs or be met with more than Reciprocity by the U.S.A. Trade must be fair and no longer a one way street!” Trump said in a tweet.
