President Donald Trump said the sweeping tariffs that he has imposed on Mexico, Canada and China may cause "short term" pain for Americans as global markets reflected concerns the levies could undermine growth and reignite inflation.

Canada’s prime minister and Mexico’s president have ordered retaliatory tariffs against Americans, following through with their threats after U.S.

President Donald Trump on Sunday defended his decision to impose broad tariffs on Canada, Mexico and China, acknowledging they may cause “some pain” but claiming it “will all be worth the price,” as the import taxes have been widely condemned by business groups and economists who warn they’ll raise prices for American consumers.
