President Donald Trump confirmed Thursday that he’s planning to levy a 25% tariff on imports from Mexico and Canada starting Saturday—with broader import taxes potentially soon following—reflecting his campaign promises to implement high tariffs, against the views of many economists who believe Trump’s plan would burden everyday consumers.

President Donald Trump will move forward with aggressive new tariffs on Canada, Mexico and China on Saturday, the White House said, affirming he will stick to his February 1 deadline for the new duties that could have widespread effects on the economy.

New trade penalties against Canada, Mexico and China that President Trump plans to impose could mean higher inflation and possible disruptions to the global economy.
