Trump says he will sign an executive order imposing a 25% tariff on all goods coming from Mexico and Canada and a 10% tariff on those from China.

Donald Trump has levelled his most severe threat against Canada in years, warning that on his very first day on office he will impose a 25 per cent tariff on all goods from Canada and Mexico, unless those countries curb the flow of drugs and migrants over their borders.

President-elect Donald Trump said he plans to impose 25% tariffs on all imports from Mexico and Canada and an additional 10% on goods from China, in moves likely to ramp up tensions with America's three top trading partners.
