USTR Greer + Mexico's Ebrard formally launch bilateral USMCA pre-review track #

On March 18, 2026, USTR Jamieson Greer met Mexico's Secretary of Economy Marcelo Ebrard in Washington to formally open bilateral USMCA review discussions, ahead of the July 1, 2026 first joint review. The published agenda: increasing US and Mexican production, limiting non-market inputs into North American supply chains, and identifying gaps in key supply chains. Canada was not included in this bilateral track — the meeting reads as a US-MX positioning channel rather than a trilateral preparatory.
