<h2>What is the Sea Lion oil project?</h2>Sea Lion is an offshore oil field located about 220 kilometres north of the Falkland Islands, known as the Malvinas in Argentina.The project is operated by Israel's Navitas Petroleum, which holds a 65 per cent interest, while Britain's Rockhopper Exploration owns the remaining 35 per cent. The companies say they operate under petroleum licences granted by the Falkland Islands government.Navitas says the project has received final investment approval and that first oil is planned for March 2028. The first phase involves 11 subsea wells connected to a floating production, storage and offloading vessel.The companies have rejected Argentina's position and said their licences were lawfully issued by the Falkland Islands government with UK backing.Also read | <a href="https://www.wionews.com/world/uss-dwight-d-eisenhower-mishap-4-sailors-injured-2-aviators-eject-during-aircraft-recovery-1790662951742">USS Dwight D. Eisenhower mishap: 4 sailors injured, 2 aviators eject during aircraft recovery</a><h2>Why Argentina is challenging the project</h2>Buenos Aires argues that unilateral development of natural resources in the disputed territory violates UN resolutions calling on Argentina and Britain to avoid actions that could complicate efforts to resolve their sovereignty dispute.Milei's government has already taken measures against companies and individuals linked to hydrocarbon activities around the Falklands. The latest move would take the dispute into international arbitration under the Law of the Sea Convention.<h2>UK backs Falkland Islanders' right to develop resources</h2>Britain maintains that the Falkland Islands are a British Overseas Territory and supports the islanders' right to develop their natural resources.The UK government earlier said that the Falkland Islands have the right to develop hydrocarbons for their own economic benefit and that it fully supports companies conducting lawful business there.&nbsp;

Argentina has escalated its long-running Falklands dispute with the UK, giving London two weeks to halt the Sea Lion oil project or face international arbitration. Javier Milei says the offshore development amounts to unauthorised exploitation of resources claimed by Argentina.

Falklands oil row: Argentina threatens legal action against UK over Sea Lion project, says ‘if within two weeks…’

Argentine President Javier Milei has accused the United Nations of failing to enforce its own resolutions on the Falkland Islands, warning that Buenos Aires will not simply wait for international institutions to act as a dispute with Britain intensifies over offshore oil exploration. Attacking the world body, Milei said it was a "useless organisation" filled with "arrogant parasites."Speaking at the 81st UN General Assembly in New York on Wednesday(Sep 23), Milei said the UN had “looked the other way” on the sovereignty dispute over the islands, which Argentina calls the Malvinas. His comments came as his government stepped up action against companies linked to the Sea Lion oil project in the North Falkland Basin.“Argentina is not going to sit around waiting for the UN and the international community to live up to their own mandate,” Milei warned. “We’re going to take matters into our own hands.”Also read | <a href="https://www.wionews.com/world/what-kind-of-confession-is-this-pakistan-pm-shehbaz-sharif-s-terrorists-would-be-roaming-new-york-remark-goes-viral-raises-alarm-online-watch-1790136284702">'What kind of confession is this?': Pakistan PM Shehbaz Sharif’s 'terrorists would be roaming New York' remark goes viral, raises alarm online.
