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.

The U.S. will impose 25% tariffs on Canada and Mexico, along with 10% on China, White House spokeswoman Karoline Leavitt said on Friday, but she declined to say whether there will be exemptions.

The move could devastate international trade and manufacturing, especially for an automotive industry with operations integrated across North America.
