Argentine President Javier Milei has issued a two‑week ultimatum to the United Kingdom to suspend activity at the Sea Lion oilfield off the Falkland Islands, warning that Buenos Aires will pursue international legal action if work continues.
What Milei Has Demanded
Milei published the deadline on social media and said he has instructed Argentina's foreign ministry and legal teams to initiate international arbitration if operations are not halted within 14 days. He added that, should activity persist beyond that window, Argentina would escalate the dispute to the International Tribunal for the Law of the Sea.
"I have instructed the Foreign Ministry and legal teams to initiate international arbitration" over what he called "the illegal plundering of our resources through the Sea Lion Project."
Project Details
The Sea Lion development lies about 220 km north of the Falkland Islands within production licences PL032 and PL004b. Rockhopper Exploration estimates the field contains roughly 1.7 billion barrels of oil in place. The project is led by Tel Aviv‑listed Navitas Petroleum (65% working interest) with London‑listed Rockhopper holding the remaining 35%.
Navitas Petroleum Development and Production (Navitas' UK subsidiary) and Rockhopper have taken a final investment decision (FID) on the Sea Lion Northern Development after securing regulatory approvals and financing. Companies involved expect extraction to begin by March 2028, with preparatory development work possibly starting in the coming months.
Political And Legal Context
Milei has sharply criticised the United Nations for what he described as inaction over the long‑running sovereignty dispute, calling the UN "a useless organisation" and accusing some officials of being "arrogant parasites dressed up as well‑intentioned bureaucrats."
Earlier this month he said he plans to send an urgent sovereignty defence bill to Congress that would toughen penalties on companies operating around the islands without Argentine authorisation. Proposed measures would broaden sanctions to target corporate directors, shareholders and suppliers linked to such activity.
UK Response And Background
UK Defence Secretary Wes Streeting responded that Argentina "lacks the ability" to retake the Falklands by force, according to the BBC. The sovereignty of the islands — known in Argentina as Las Malvinas — has been disputed since the 1982 conflict when a British task force reclaimed the territory following Argentine occupation. In a 2013 referendum, 99.8% of island residents voted to remain a British Overseas Territory.
