Trump Says U.S. Will Impose Metal Tariffs on Brazil and Argentina

WASHINGTON — President Trump said on Monday that he would impose tariffs on steel and aluminum from Brazil and Argentina, a move that would shatter previous agreements with those countries and widen a global trade war that the president had appeared ready to scale back.

Mr. Trump, in a message on Twitter, accused Brazil and Argentina of manipulating their currencies and hurting American farmers. “Therefore, effective immediately, I will restore the Tariffs on all Steel & Aluminum that is shipped into the U.S. from those countries.”
