The UK has halted plans to hand over the Chagos Islands to Mauritius after the Trump administration withdrew support for the deal. UK officials accepted that time had run out to pass the legislation without US backing, which was required to amend the 1966 British-American treaty governing the islands. This marks a shift in the Trump administration's foreign policy on the Indo-Pacific and leaves Mauritius without its expected territorial gain, though Mauritian officials pledged to continue efforts to regain control of the islands.
