Canadian Prime Minister Justin Trudeau said Monday in a social media post that the United States had agreed to pause threatened tariffs for “at least 30 days.” The announcement followed two phone calls with President Donald Trump on Monday and came after the United States and Mexico reached a similar agreement.

The pauses—which allow a period of negotiations over drug trafficking and border security—provide a cool-down period after a tumultuous few days that put North America on the cusp of a trade war.
