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.

Canada initially ordered tariffs of 25% on American imports starting Tuesday, including beverages, cosmetics and paper products worth 30 billion Canadian dollars ($20 billion). Mexico has so far said only that it will impose retaliatory tariffs,

Trump’s move to impose new tariffs has bewildered the United States’ closest allies and trading partners, who have vowed to respond with levies of their own.
