Canadian officials are undertaking a “full court press” in Washington this week to avert 25% tariffs on most Canadian goods that President Donald Trump has threatened to impose next month, says a minister in Justin Trudeau’s cabinet.

President Donald Trump said Thursday that tariffs on goods from Canada and Mexico will increase sharply on Tuesday and, in an unexpected move, also announced an additional 10 percent tax on Chinese goods that will take effect then.

The president also said he would impose an additional 10 percent tariff on China as he tries to force other countries to take more action on drug shipments.
