US President Donald Trump says he will pause tariffs on Canada and Mexico for a month, but levies on China are still set to take effect on February 4.

Trump agreed to delay tariffs on Canada and Mexico after their leaders agreed to measures to stop the flow of the opioid fentanyl into the U.S.

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.
