Sheinbaum made the announcement on social media Monday morning, roughly 12 hours before the tariffs were set to take effect. Trump and Sheinbaum spoke on Monday and agreed that Mexico will do more to combat drug trafficking into the U.S., and that the U.S. will step up efforts to block the flow of firearms into Mexico.

Sheinbaum also said officials with the U.S. and Mexico were beginning talks on wider trade and security issues.
