Federal Legislation
Senate Seeks Approval for Diego Garcia Treaty Changes
March 14, 2026
Senator John Kennedy introduced the Diego Garcia Treaty Oversight Act to require U.S. Senate approval before any modifications to the 1966 treaty between the U.S. and U.K. concerning the British Indian Ocean Territory, specifically prohibiting the ceding of the Diego Garcia military base to Mauritius without Senate consent. The bill also bans federal funding for treaty changes absent Senate approval and mandates congressional reporting on national security impacts. This legislative action directly affects defense-related procurement and operational control of the Naval Support Facility Diego Garcia, a strategic military installation.
- Why this matters: Procurement professionals should anticipate potential shifts in operational control and funding restrictions related to Diego Garcia, which could impact defense contracts and logistics tied to this facility.
- The bill underscores increased congressional oversight on international treaties affecting U.S. military bases, signaling tighter controls on procurement and funding linked to such agreements.
- Contractors engaged in defense services or infrastructure at Diego Garcia should evaluate risks related to treaty modifications and prepare for possible changes in contract terms or funding availability.
- Agencies involved in treaty negotiations and defense procurement must coordinate closely with Congress to ensure compliance with new reporting and approval requirements.
When two countries shake hands on a treaty, one of them can’t start changing the terms without the other country agreeing to it. That’s just common sense. That’s why I take issue with the United Kingdom trying to give our joint military base on Diego Garcia to a pal of Xi Jinping’s—all without getting the U.S. Senate’s consent. My bill would make sure that our friends in the U.K. don’t modify our treaty and hand this gift to China without giving the Senate a say.
