Trump declared an economic emergency in order to place duties of 10% on all imports from China and 25% on imports from Mexico and Canada.

Canada will retaliate against President Donald Trump'snew tariffs with 25% levies on a raft of U.S. imports, Prime Minister Justin Trudeau said on Saturday, warning Americans that Trump's actions would have real consequences for them.

Trump has long proposed raising tariffs—or taxes on imported goods that the businesses importing them pay the U.S. government—before the election, and said in November he’ll impose a 25% tariff rate on all imports from Mexico and Canada on the first day of his presidency and will impose an additional 10% tariff rate on all imports from China on top of other tariffs.
