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.

Leavitt implied that there’s not much the impacted parties can do to avoid the duties at this point. “Tariffs are incoming tomorrow…And the reason for that is because both Canada and Mexico have allowed an unprecedented invasion of illegal fentanyl that is killing American citizens—and also illegal immigrants—into our country,” she said.
