President Donald Trump said the US will put a 35% tariff on some imports from Canada, escalating the tensions between two countries that have impaired one of the world’s largest trading relationships.

The Trump administration raised the tariff rate on some Canadian imports to 35% from 25%. Carney has described the talks with the US as difficult, but officials said recent talks had been “informative, constructive and cordial”, and reiterated mutual benefits for both economies.

U.S. President Donald Trump on Thursday signed an executive order increasing tariffs on Canadian goods to 35% from 25% on all products not covered by the U.S.-Mexico-Canada trade agreement, the White House said.
