President-elect Donald Trump said he would require countries that are part of BRICS — a China- and Russia-backed group of emerging economies — to commit to not creating new currency or face 100% tariffs during his administration.

Trump, who takes office on Jan. 20, said he would impose a 25% tariff on imports from Canada and Mexico until they clamped down on drugs, particularly fentanyl, and migrants crossing the border, in a move that would appear to violate a free-trade deal.
