The U.S. president pulled the plug on monthslong negotiations over what he called an “egregious” digital-services tax on U.S. tech companies, plunging relations with America’s second-largest trading partner back into turmoil.

The president said he would cease negotiations and impose new tariffs because of Canada’s imminent, new digital services taxes.

President Donald Trump says he’s suspending trade talks with Canada over its plans to continue with its tax on technology firms.
