Argentina Takes Falklands Oil Dispute With UK To International Tribunal

Argentina has approached an international maritime tribunal to halt a $2.2-billion offshore oil project near the disputed Falkland Islands, escalating its long-running confrontation with the United Kingdom over sovereignty and access to natural resources.

President Javier Milei’s government filed a request for provisional measures with the International Tribunal for the Law of the Sea (ITLOS) in Hamburg, Germany, on Tuesday, October 13, seeking to stop the Sea Lion project and protect what it describes as Argentina’s sovereign rights. The move adds an international legal dimension to the dispute over oil exploration near the British-controlled archipelago.

The dispute centres on the Sea Lion oilfield, located about 220 kilometres (140 miles) north of the islands. The project is being developed by Israel’s Navitas Petroleum and Britain’s Rockhopper Exploration, with production expected to begin in 2028. After years of delays and disruptions, the project could transform the islands’ small, fishing-dependent economy.

Argentina has intensified its campaign against oil exploration around the islands, which it calls the Malvinas. Milei has described the emerging oil industry as a threat to Argentina’s sovereignty and accused those involved of exploiting the country’s natural resources. His government has launched criminal proceedings against executives and shareholders linked to the project and proposed legislation to expand sanctions against companies and suppliers operating without Argentine authorisation.

The UK has rejected Argentina’s claims of jurisdiction over the project. Foreign Office Minister Uma Kumaran told the House of Commons on Tuesday that the oilfield lies on the Falklands’ continental shelf and that its development is lawful under licences issued by the islands’ elected government. She accused Argentina of using economic coercion and pledged continued British support for the islanders and companies operating there.

The dispute has also created uncertainty for contractors involved in the project. Argentina has sought to increase pressure on businesses associated with the islands’ natural resources, while Britain has defended the islanders’ right to develop their resources.

The Falkland Islands have been under British control since 1833, although Argentina continues to claim sovereignty over the archipelago. In 1982, Argentina’s military dictatorship invaded the islands, triggering a 10-week war that ended in Argentine surrender. The conflict killed 649 Argentine troops, 255 British personnel and three islanders.
