The Trump administration said Saturday it had imposed a 25% tariff on goods from Canada and Mexico and a 10% tariff on China.

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 United States and its biggest trading partners were hurtling Sunday into a new era of protectionism as Canada, Mexico and China said they would adopt countermeasures against new tariffs levied by President Donald Trump.
