标题:T’s new tariffs are his most extreme ever

America targets its three biggest trading partners: Canada, Mexico and China

正文：He has actually gone and done it. President D.T. had long threatened to impose hefty tariffs on Canada and Mexico, America’s two biggest trading partners. Last month, when they were first due to take effect, he offered both countries a last-minute reprieve. This time, he was in no mood to play nice. New tariffs came into effect at 12:01 am EST on March 4th, when America hit imports from its two neighbours with levies of 25%. For good measure, Mr. T added another 10% tariff on Chinese goods, on top of the 10% charge he implemented last month, which itself added to tariffs imposed in his first term.
