SOUTH AMERICA/TARIFFS/TRUMP AS PRESIDENT: “President Trump said on Monday [12-2-19] 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.’ The United States exempted Brazil, Argentina and other countries from the president’s sweeping metal tariffs in March 2018, with the United States saying it would continue negotiations with those countries to improve their trade terms. In May 2018, the United States announced that it had reached an agreement with Brazil and Argentina that would cap their metal shipments at a specific volume each year.”
