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.

The president had promised action, though his team had been in negotiations over how to potentially dial back tariffs.

Even as Canada’s prime minister announced more than $100 billion in retaliatory tariffs, he made clear that he was imposing them reluctantly.
