In short
- Argentina has asked the International Tribunal for the Law of the Sea, based in Hamburg, to block oil and gas exploration north of the Falkland Islands that it says the UK authorised illegally.
- The Sea Lion oilfield lies about 130 miles (209 km) north of the Falkland Islands and is estimated to contain 1.7 billion barrels of oil.
- Britain’s Rockhopper Exploration and Israel’s Navitas Petroleum hold the Sea Lion licences, which the Falkland Islands government extended last month; production is expected to start in 2028.
- UK Foreign Office minister Uma Kumaran accused Argentina of “economic coercion” against the roughly 3,500 inhabitants of the Falkland Islands.
- Foreign Secretary Ed Miliband said Argentina’s attempts to intimidate businesses engaged in legitimate commercial activity are unacceptable.
Argentina has lodged a claim with the International Tribunal for the Law of the Sea seeking to halt oil and gas exploration north of the Falkland Islands, which Buenos Aires says the United Kingdom authorised illegally. The UK government says it will engage with the tribunal but resist the claim firmly.
What is Argentina asking the tribunal to do?
The application lodged by the Argentine government seeks to preserve Argentina’s sovereign rights over its continental shelf and to prevent activities it says the United Kingdom authorised “unilaterally and illegally”, according to a statement from Buenos Aires. Argentine Foreign Affairs Minister Pablo Quirno said in a post on X that the government is requesting a number of orders against the UK, including halting new exploration permits. The tribunal is an independent judicial body based in Hamburg which applies the United Nations Convention on the Law of the Sea.
What is the Sea Lion oilfield and who holds the licences?
The Sea Lion oilfield lies around 130 miles (209 km) north of the Falkland Islands and is estimated to contain 1.7 billion barrels of oil. Britain’s Rockhopper Exploration and Israel’s Navitas Petroleum have insisted they hold valid licences issued by Britain. The filing comes a fortnight after Argentine President Javier Milei demanded the scrapping of the Sea Lion project, having also set a two-week deadline for the UK over the Falklands oil project. The Falkland Islands government extended exploration licences last month, and the field is expected to start pumping in 2028, potentially generating large revenues for the roughly 3,500 inhabitants of the islands.
How has the UK responded?
UK Foreign Office minister Uma Kumaran criticised what she called the “escalating campaign” from Argentina against companies operating in the Falklands and accused the Argentine government of “economic coercion” against the people of the islands. “We will do whatever it takes to support them,” Kumaran told the House of Commons on Tuesday. The UK is introducing measures under the Protection of Trading Interests Act to shield firms from any extra-territorial impact of Argentine laws, after Milei threatened to impose economic sanctions on companies exploiting oil close to the islands, a campaign that has included sanctions proceedings over the Falklands against 45 people.
Foreign Secretary Ed Miliband said: “Argentina’s attempts to intimidate businesses and individuals engaged in legitimate commercial activity are unacceptable. Companies should be free to make lawful commercial decisions without the threat of political coercion.” Kumaran said the tribunal application “does not invalidate licenses issued by the Falkland Islands government, alter the islands’ regulatory authority, or require lawful hydrocarbon development activities to cease”.
Why are tensions rising between the UK and Argentina?
Milei used his speech at the UN General Assembly late last month to criticise the UN for failing to act over the sovereignty of the Falkland Islands, remarks in which he also threatened unilateral action on the Falklands. He said the UN had become “a useless organisation” that only serves “arrogant parasites dressed up as well-intentioned bureaucrats”. Kumaran described those remarks, delivered in New York, as “inflammatory”. Argentina has maintained its claim to the Falkland Islands since its defeat in the 1982 war, and UK officials believe the current Argentine leadership is deliberately picking a fight ahead of elections next year.
The Foreign, Commonwealth and Development Office has said the UK will engage with the tribunal but resist Argentina’s claim firmly, without escalating the dispute, while reassuring businesses fearful of Argentine retribution.
