The United States is extending its pursuit of Iran-linked vessels beyond the Middle East into the Indo-Pacific, with satellite imagery showing the expeditionary base ship USS Miguel Keith heading toward the Strait of Malacca as of Thursday local time, CNN reported.

The US 7th Fleet confirmed that American forces would track and interdict Iran-linked ships in waters outside the Middle East, specifically naming the Indo-Pacific theatre. The shift marks the first time the military confrontation with Tehran has been pushed into Sri Lanka’s immediate maritime neighbourhood, a significant geographic expansion of what until now had been a Persian Gulf operation.

The Strait of Malacca is Sri Lanka’s primary maritime corridor, carrying the overwhelming share of the country’s fuel, industrial goods and export shipping. It is an entirely separate chokepoint from the Strait of Hormuz, which remains the focus of ongoing diplomatic manoeuvring following Iran’s FM declaration that the Gulf waterway was “completely open” and the IRGC’s subsequent reversal placing it back under “strict management”.

The development comes as President Donald Trump signalled he may not extend a tentative US-Iran ceasefire if negotiations fail to produce a deal by Wednesday. A second round of peace talks is expected Monday in Islamabad, according to Iranian sources cited by CNN, though US officials have not publicly confirmed the schedule.

For Sri Lanka, increased US naval activity near the Malacca entry adds a fresh layer of geopolitical risk to fuel and freight shipments already exposed to the ongoing Hormuz fragility and the recent armed incidents against merchant vessels in the Gulf. Insurance premiums and vessel routing decisions through Southeast Asia are likely to come under renewed scrutiny if the US enforcement footprint widens.

Trump separately said Chinese President Xi Jinping was “very happy” about the Hormuz opening, ahead of the two leaders’ planned talks in May.
