In a pair of social media posts, Trump said he'd take executive action, imposing a 25% tax on all products entering the U.S. from Mexico and Canada and another 10% on goods from China.

Donald Trump says he will impose a 25% tariff on goods coming from Mexico and Canada, plus an extra 10% on Chinese goods.

The president-elect said that he would impose the across-the-board tariffs on Day 1 and that they would stay in place until Canada, Mexico and China halted the flow of drugs and migrants.
