Overview
- Technical teams held a fifth binational session, with Mexico submitting an initial plan, the U.S. issuing a same‑day response, and Mexico sending a counterproposal overnight.
- President Trump is demanding 200,000 acre‑feet — about 246.6 million cubic meters — be delivered by Dec. 31 under threat of a 5% tariff on Mexican goods.
- Mexican officials report a remaining delivery shortfall of a little over one billion cubic meters attributed to extraordinary drought in the border basins.
- Claudia Sheinbaum rules out a full renegotiation, citing treaty mechanisms such as replenishment in the next cycle and CILA actas to structure compliant deliveries.
- Negotiations involve senior officials, including Roberto Velasco, Julio Berdegué, Alicia Bárcena, and Efraín Morales on the Mexican side, and Brooke Rollins and Christopher Landau for the United States, as Trump also highlights cross‑border sewage concerns from Tijuana.
