Argentina's President Javier Milei has threatened to initiate legal action against the British government unless it ceases oil exploration activities off the coast of the Falkland Islands. In a social media post, Milei set a two-week deadline for the Sea Lion oilfield project, a joint venture between Israeli and British companies, to be terminated. The companies involved assert that they possess valid licenses issued by the UK.
Milei's comments escalate tensions between the UK and Argentina regarding the sovereignty of the Falkland Islands, referred to as Las Malvinas in Argentina, more than 40 years after a British military task force expelled Argentine forces from the territory in 1982. He stated that if the deadline is not met, he has directed the Foreign Ministry and legal teams to pursue international arbitration against the UK, alleging "the illegal plundering of our resources through the Sea Lion Project."
Milei warned that if the "illegitimate exploitation" of the region does not cease within two weeks, Argentina would escalate the matter to the International Tribunal for the Law of the Sea, an independent judicial body based in Hamburg responsible for the application of the United Nations' Convention on the Law of the Sea.
This announcement follows Milei's criticism of the UN during his speech at the General Assembly, where he described the organization as "a useless organisation" that serves "arrogant parasites dressed up as well-intentioned bureaucrats."
In response, UK Defence Secretary Wes Streeting remarked that Argentina "lacks the ability" to reclaim the Falklands by force. Milei previously characterized the Sea Lion oilfield as a "clear and present danger." The Sea Lion oilfield, located approximately 130 miles (209 km) from the Falkland Islands, is estimated to contain 1.7 billion barrels of oil.
The oil companies involved, Britain's Rockhopper Exploration and Israel's Navitas Petroleum, plan to begin extraction from the oilfield within two years and have previously emphasized that they hold valid licenses from the Falkland Islands. In a 2013 referendum, island residents voted overwhelmingly to remain a British overseas territory, with 99.8% in favor and only three votes against.
The Falklands conflict in 1982 resulted in the deaths of 255 British military personnel, three islanders, and 649 Argentine military personnel after Argentine forces landed on the islands to assert a territorial claim, leading to a 74-day war.
