Argentina gives Britain two weeks over the Sea Lion oil project
President Javier Milei gave Britain two weeks to stop work on the Sea Lion oil project near the Falkland Islands and threatened an international maritime-court application if it did not. Argentine Foreign Minister Pablo Quirno says the deadline is a procedural opportunity for London to respond before the proposed legal step. Britain and the island administration reject Argentina’s sovereignty claim. No tribunal has ordered a halt to the project.

A two-week demand over Sea Lion
Argentine President Javier Milei gave Britain two weeks to halt work on the Sea Lion oil project near the Falkland Islands. The BBC reported the ultimatum; A24 interviewed Foreign Minister Pablo Quirno about the same decision. Quirno said the interval gives London an opportunity to stop the disputed activity before Argentina seeks an international legal remedy. The announcement is an escalation in a long-running sovereignty dispute, not a court order against the project. The Argentine government says it intends to start arbitration under Annex VII of the UN Convention on the Law of the Sea. It also says it may seek provisional measures from the International Tribunal for the Law of the Sea if Britain does not act within the two-week period. These are distinct steps: notifying a dispute and threatening to request interim relief do not mean judges have granted relief. The BBC reports the plan as Argentina’s position.[1], [2]
The project and the competing positions
Sea Lion is an oil development off the islands, with Britain’s Rockhopper Exploration and Israel’s Navitas Petroleum as partners. The BBC says the companies plan to begin extraction within two years and maintain that their licences are valid. Argentina considers the waters part of its continental shelf and rejects the authority under which the project proceeds. A24 reports Quirno’s argument that London should not make unilateral decisions there. Britain and the island administration reject Argentina’s sovereignty claim. The islands were the subject of a war between Britain and Argentina in 1982; islanders voted to remain a British overseas territory in a 2013 referendum. Buenos Aires does not regard that vote as settling its claim. This history explains why an oil project becomes a state-to-state dispute. It does not decide which legal interpretation an international tribunal would accept.[1], [2]
What the deadline changes
Quirno told A24 that the two weeks are a procedural chance for the other side to halt activity before the planned arbitration move. His claim that the project violates Argentine and international law is the Argentine government’s argument, not an established judicial finding. The BBC likewise presents the deadline as a threat of legal action. Neither report says Britain has agreed to stop work or that an international tribunal has accepted jurisdiction. The immediate consequence is therefore a dated diplomatic and legal demand. Britain can respond during the interval, and Argentina says it will seek further proceedings if the disputed work continues. Whether the project changes course will depend on those subsequent actions, not the ultimatum alone. The two publishers establish the same new step while leaving the rival claims and the project’s eventual legal status unresolved.[1], [2]
