White House Considers Purchasing Chagos Islands From Mauritius to Secure Diego Garcia Base

BLUFWashington's pivot from blocking Britain's Chagos deal to exploring outright purchase signals that lease arrangements, however long, no longer satisfy US requirements for unconstrained basing access at Diego Garcia.

The Telegraph reported on June 7 that the White House is examining a direct purchase of the Chagos Islands from Mauritius, listed in an internal policy paper as one option alongside alternatives to Britain's shelved sovereignty-transfer deal, though not currently the administration's preferred choice 1. A US official confirmed to Reuters that Trump remains opposed to Britain ceding the territory and called Diego Garcia a "vital and indispensable military installation" for US national security 2. Trump administration officials cited Mauritius's ties to Iran and China as the security concern driving the purchase option 13. Mauritius denied receiving any US proposal and stated its sovereignty over the archipelago is non-negotiable; Reuters separately stated it could not independently confirm the Telegraph's reporting 3.

Analysis
Listing a direct-purchase option in a White House policy paper marks a qualitative shift from blocking the UK-Mauritius sovereignty transfer to seeking US sovereign control of the archipelago. Having already forced London to shelve ratification, the administration has closed the lease-based path. Security concerns about Mauritius's ties to Iran and China cannot be addressed through lease guarantees, which leaves ownership as the administration's logical floor. The option may instead function as coercive pressure on Mauritius and Britain to accept revised lease terms rather than signal genuine acquisition intent. Confidence is low: the Telegraph is the sole primary source, Reuters could not independently confirm, and no party to the discussions has issued an official statement.
