President-elect Donald Trump said Monday that he will issue executive orders imposing new tariffs on all imported goods from China, Mexico and Canada, the nation’s three largest trading partners, upon returning to the White House.

In a post on Truth Social, Mr. Trump mentioned a caravan of migrants making its way to the United States from Mexico, and said he would use an executive order to levy a 25 percent tariff on goods from Canada and Mexico until drugs and migrants stopped coming over the border.
