Argentina’s President Javier Milei has given the UK two weeks to stop the Sea Lion oil project near the Falkland Islands, warning that Argentina will pursue international legal action if the work continues.
In a social media post on Tuesday, the Argentine leader set a strict two-week deadline for the Sea Lion oilfield project to be completely scrapped. The project is a joint venture between British and Israeli energy companies operating under valid licences issued by the UK government. The site is located in the North Falkland Basin and has been in the exploration phase for several years, though actual drilling has faced delays due to technical and environmental assessments.
Milei made his position clear, warning that failure to meet the deadline would trigger immediate international action. “I have instructed the Foreign Ministry and legal teams to initiate international arbitration against the UK over the illegal plundering of our resources through the Sea Lion Project,” he stated.
He further warned that if the “illegitimate exploitation” of the region did not end within the two-week window, Argentina would take the matter directly before the International Tribunal for the Law of the Sea. This independent judicial body, based in Hamburg, Germany, is responsible for applying the United Nations Convention on the Law of the Sea to global maritime disputes.

The sudden ultimatum sharply heightens tensions between London and Buenos Aires over the sovereignty of the remote archipelago, which Argentina refers to as Las Malvinas.
This dispute echoes a dark chapter in history, coming more than 40 years after a British military task force was sent to eject Argentine forces that had invaded and occupied the territory in 1982. The brief but deadly war left hundreds of soldiers dead on both sides and cemented British control over the islands ever since.
Despite Argentina’s renewed claims and strong rhetoric, the people actually living on the islands have consistently chosen to remain under British rule. In a 2013 referendum organized by the Falkland Islands government, a massive 99.8% of voters supported remaining an overseas territory of the UK.
Successive British governments have long maintained that the islanders have an absolute right to self-determination under international law, as established by the United Nations Charter. London insists that any discussion about the islands’ future must start with the wishes of the people who call it home.
As the two-week clock begins to tick, the international community is watching closely to see if this is merely political posturing or the start of a genuine legal battle. The outcome will test whether decades-old territorial wounds can be reopened by the modern promise of offshore oil.
