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.

President-elect Trump's plan to increase tariffs on goods from China and impose them on products from Mexico and Canada would drive inflation up by nearly 1%, Goldman Sachs estimates.
