· On Feb 27, 2026, Mauritius suspended diplomatic relations with the Maldives after Male refused to recognize Mauritian sovereignty over the Chagos Archipelago. · The dispute stems from the 2025 UK–Mauritius agreement: London agreed to transfer sovereignty of the Chagos Archipelago to Mauritius while leasing back the strategic Diego Garcia base to the UK and US for 99 years. · This deal was supposed to close a long colonial chapter. Instead, it has opened a new geopolitical front in the Indian Ocean. · The turning point came when Maldivian President Mohamed Muizzu reversed the policy of his predecessor and withdrew recognition of Mauritian sovereignty over Chagos. · Muizzu argues the UK–Mauritius deal ignores Maldivian interests and overlaps with maritime zones that the Maldives considers part of its Exclusive Economic Zone (EEZ). · The dispute is not only political — it is maritime and strategic. Control of EEZ boundaries means access to fisheries, seabed resources, and influence over major sea lanes. · Ironically, earlier legal developments appeared to favor Mauritius. Between 2021 and 2023, international maritime rulings used Mauritius as the relevant coastal state when delimiting boundaries near Chagos. · The Maldives now rejects those interpretations and is preparing legal options that could include challenging the Chagos settlement before international courts. · On the ground, tensions are rising. Reports indicate the Maldives has increased coast guard patrols and drone surveillance in waters linked to the disputed maritime zones. · Mauritius responded forcefully. By suspending diplomatic relations, Port Louis signaled that the Maldivian position — denying Mauritian sovereignty over Chagos — is unacceptable. · This diplomatic rupture adds new uncertainty to a deal already under scrutiny internationally. The stakes are bigger than a bilateral dispute. The Chagos Archipelago hosts Diego Garcia, one of the most important US military bases in the Indo-Pacific. · Regional actors are watching closely. India, which supports Mauritian sovereignty over Chagos, is concerned about rising tensions in its maritime neighborhood. · Whether such a challenge materializes remains uncertain. But the diplomatic clash has clearly complicated the final settlement of the Chagos question. For Mauritius, the issue is about decolonization and sovereignty. For the Maldives, it is about maritime rights and regional influence.
