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

Trump tested the waters on tariffs during his first four years in office. Almost immediately, “Trump hit a slew of countries with tariffs on steel and aluminum,” according to the New York Times, then “wielded those taxes as leverage against Canada and Mexico to renegotiate NAFTA.”
