Trump's trade war among allies triggers retaliation from Canada and Mexico

Canada’s prime minister and Mexico’s president have ordered retaliatory tariffs against Americans, following through with their threats after U.S. Donald Trump sparked a trade war by imposing sweeping tariffs on imports from Canada, Mexico and China. Canada had been very proactive for months saying it will retaliate, while Mexico kept a more cautious approach on recent weeks, but in the end both did what they had promised: retaliate. Prime Minister Justin Trudeau and Mexican Claudia Sheinbaum spoke in a telephone call before Trudeau announced Canada’s retaliatory tariffs but there is no indication the two countries are coordinating responses.
