KONTAN.CO.ID - WASHINGTON. U.S. President Donald Trump on Monday said he would restore tariffs on U.S. steel and aluminum imports from Brazil and Argentina, surprising officials in the two South American countries who sought explanations.

Emerging market stocks and the highly sensitive Mexican peso slid to session lows following Trump’s early morning post on Twitter that gave no details on the plan.

Representatives for the Office of the U.S. Trade Representative could not be reached for comment.

“Brazil and Argentina have been presiding over a massive devaluation of their currencies, which is not good for our farmers. Therefore, effective immediately, I will restore the Tariffs on all Steel & Aluminum that is shipped into the U.S. from those countries,” Trump wrote.

Brazil’s President Jair Bolsonaro, an avowed Trump fan who has sought closer U.S. ties, said in local radio interview that he would call his U.S. counterpart, who he was confident would listen to Brazil’s concerns.

“Their economy is not comparable with ours, it’s many times bigger. I don’t see this as retaliation,” Bolsonaro said in a radio interview with Brazil’s Radio Itatiaia.

“I’m going to call him so that he doesn’t penalize us ... Our economy basically comes from commodities, it’s what we’ve got. I hope that he understands ...and I’m almost certain he’ll listen to us,” he said.
