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.

The tariffs were also pushed through despite the terms agreed between the U.S., Canada and Mexico in the U.S.-Canada-Mexico Agreement, negotiated by Trump in his first term, after he pledged to get rid of the North American Free Trade Act (NAFTA) negotiated by President Bill Clinton.
