President Donald Trump warned Canada and Mexico to expect tariffs of 25% on exports to the United States starting Saturday. Speaking to reporters in the Oval Office on Thursday, Trump said he was following through on his campaign threat to impose border taxes on America's neighbors immediately to the north and south of the continental United States over inflows of illegal migrants and drugs and large trade deficits.

If U.S. President Donald Trump follows through on his pledge to slap 25% tariffs on imports from Mexico it could usher in a volatile new chapter in the longstanding trade relationship with the impacts hitting consumers.

US President Donald Trump has said he will follow through with his threat to hit imports from Canada and Mexico with 25% border taxes, known as tariffs, on 1 February. But he added that a decision about whether this would include oil from those countries had not yet been made.
