S.4019

The Diego Garcia Treaty Oversight Act mandates Senate approval for any modifications to the 1966 agreement between the U.S. and the U.K.

The Diego Garcia Treaty Oversight Act requires the President to submit a report to Congress before negotiating any changes to the 1966 agreement concerning the British Indian Ocean Territory. The report must detail the national security rationale, implications for U.S. control of Diego Garcia, and risks from third-party claims or foreign military presence. Federal funds cannot be used to modify the agreement without Senate approval. The agreement in question is the 1966 Exchange of notes between the U.S. and the U.K. regarding the territory's availability for defense purposes.
