Doubling down on his trade wars, Trump is threatening to raise taxes on many goods from Canada, hike his universal tariff on imports from around the world and punish Brazil for prosecuting his friend, the country’s former president.

On Saturday, Trump announced more tariffs still, this time on two of the United States’ biggest trade partners: the European Union and Mexico, at 30% each.

Former U.S. trade negotiator Wendy Cutler said that Trump’s recent moves “underscore the growing unpredictability, incoherence and assertiveness’’ of his trade policies. “It’s hard for trading partners to know where they stand with Trump on any given day and what more may be coming their way when least expected,’’ said Cutler, now vice president at the Asia Society Policy Institute.
