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.

White House press secretary Karoline Leavitt said that there will be 25% tariffs on imports from Canada and Mexico and 10% tariffs on goods from China starting on Saturday. This fulfills Trump’s repeated promise to implement tariffs on these countries throughout his campaign.

Stocks on Wall Street surrendered early gains and closed broadly lower Friday after the White House said President Donald Trump would impose promised tariffs on key U.S. trading partners. The S&P 500 fell 0.
