The Trump administration said Saturday it would levy 25% import tariffs on goods from Mexico and Canada, with Canadian energy products facing a 10% tariff. The announcement also includes an extra 10% tariff on imports from China.

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.

President Donald Trump signed an order to put tariffs on U.S. neighbors Canada and Mexico, as well as China, starting Tuesday.
