Mexico's Sheinbaum: Texas Claim to Nine Rio Grande Islands Is Electoral, Only Bilateral Commission Can Decide

Friday, November 6, 2026 · World · GSM News

Mexican President Claudia Sheinbaum said at her morning press conference on November 3 that Texas's claim to nine islands in the Rio Grande is an electoral issue, and that Texas has no authority to settle questions of sovereignty on the border.

Texas Land Commissioner Dawn Buckingham said on October 27 that a review of historical records and surveys had confirmed the nine islands belong to the State of Texas. They are nine of 28 river islands whose ownership US Customs and Border Protection had previously questioned. Mexico's Foreign Ministry rejected any unilateral change on October 30, citing the 1970 Boundary Treaty, under which the line runs at the centre of the river's normal channel and only the International Boundary and Water Commission (CILA) can determine which side each island is on.

Sheinbaum spoke on the day of the US midterm elections. No response from Texas officials had been reported at the time of writing.
