Argentina’s President Javier Milei has issued a two‑week deadline to the United Kingdom for stopping the Sea Lion oilfield project, a joint venture between British and Israeli firms slated to begin extraction within the next two years. If the deadline is missed, Milei said he would initiate international arbitration and bring the case to the International Tribunal for the Law of the Sea, accusing the UK of illegal resource exploitation.


The Sea Lion project lies about 130 miles off the Falkland Islands and is estimated to contain 1.7 billion barrels of oil. While the contractors hold licences issued by the Falkland Islands’ authorities, Argentina rejects their validity, citing its own claim of sovereignty over the archipelago—referred to in Spanish as Las Malvinas.


Milei’s threat arrives amid a broader diplomatic spat following the UK’s 2024 announcement to expand the oilfield’s search radius. He blasted the United Nations as “a useless organisation” during a speech at the General Assembly, calling it a “parasite” that has failed to protect Argentine interests.


The UK Defence Secretary, Wes Streeting, has dismissed militant takeover of the islands as unlikely, while Argentine officials continue to demand full jurisdiction over the territory. Upsets over sovereignty reached a peak in 1982 when a British military task force expelled Argentine forces after a 74‑day conflict, resulting in heavy casualties on both sides.
