US President Donald Trump on Saturday signed an order to impose stiff tariffs on imports from Mexico, Canada and China, fulfilling a campaign promise but raising the prospect of increase prices for American consumers.

Mr Trump is declaring an economic emergency to put duties of 10% on all imports from China and 25% on imports from Mexico and Canada — America’s largest trading partners — except for a 10% rate on Canadian oil.
