President Claudia Sheinbaum met with U.S. Trade Representative Jamieson Greer on Thursday to discuss commercial issues related to the T-MEC agreement [1].

The meeting occurs during a critical review period for the trilateral trade pact, as both nations navigate economic dependencies and political pressures. The outcome of these negotiations will determine the stability of North American supply chains and trade tariffs.

The bilateral encounter took place at the Palacio Nacional in Mexico City [1]. The session lasted approximately one and a half hours [2], with Greer departing the government seat at 11:31 a.m. [2]. This meeting served as the third bilateral encounter under the current T-MEC review process [1].

Sheinbaum sought to define the boundaries of the commercial negotiations. She said that certain diplomatic and security pressures would not influence the trade talks. "Border security and water treaty are not on the T-MEC table," Sheinbaum said [1].

While the focus remained on trade, previous discussions regarding the longevity of the agreement have surfaced. Some reports indicate a proposal to extend the T-MEC agreement for an additional 16 years [3]. This extension would provide a longer window of regulatory certainty for businesses operating across the three member nations.

Despite the focus on the president's meeting, some reports differed on the primary participants of the review process. While most sources confirmed the meeting between Sheinbaum and Greer, other reports noted the involvement of Secretary of Economy Marcelo Ebrard in the review proceedings [4].

"Border security and water treaty are not on the T-MEC table,"

The insistence by the Mexican presidency that border security and water rights remain separate from T-MEC negotiations is a strategic move to prevent the U.S. from using trade leverage to force concessions on non-commercial issues. By isolating trade from security, Mexico aims to protect its economic stability while maintaining a separate diplomatic track for sensitive sovereignty and migration disputes.
