The United Kingdom (UK) has reaffirmed its position on the Falkland Islands after Argentine President Javier Milei renewed his country’s claim to the British Overseas Territory and announced tougher measures against companies involved in oil exploration around the islands.
Milei made the remarks during a televised national address on Thursday, September 3, saying Argentina would continue its efforts to recover the Falkland Islands, which Argentina calls the Malvinas. He also announced plans to strengthen sanctions against companies involved in oil and gas projects in the disputed area.
The Argentine president said his government would seek to prevent companies involved in offshore projects around the islands from operating in Argentina without authorisation from Buenos Aires. The proposed measures could also affect companies involved in the development of the Sea Lion oil project.
Milei further announced plans to increase defence resources in southern Argentina, including funding for a naval base in Tierra del Fuego. He also said his government would submit a bill to Congress aimed at strengthening Argentina’s response to activities it considers violations of its sovereignty.

The renewed dispute is partly linked to plans for oil development around the Falkland Islands. Reuters reported that the Sea Lion project, involving British company Rockhopper Exploration and Israel-based Navitas Petroleum, is expected to move ahead with drilling in the coming months. Argentina considers the project an unauthorised exploitation of resources in waters it claims.
The British government responded firmly on Friday, rejecting Argentina’s renewed claim and insisting that the Falkland Islands remain British.
UK Defence Secretary Wes Streeting said Milei’s statement reflected “domestic politics in Argentina” more than the circumstances of the islands. He said the Falklands were British because their residents chose to be British and described the UK’s commitment to the islands as “absolute and unshakeable.”
Foreign Secretary Ed Miliband also reaffirmed Britain’s position on X, saying the UK’s position on the Falkland Islands was unwavering.
“The Islands are British and will remain so because that is the overwhelming position of the Islanders,” Miliband said. He added that their right to self-determination was paramount, grounded in international law, and would be upheld by Britain.
The dispute has persisted for decades. Britain has controlled the territory since 1833, while Argentina continues to claim sovereignty over it. The two countries fought a 74-day war over the territory in 1982, which killed 649 Argentine service members and 255 British service personnel.
The latest escalation also follows recent comments by US President Donald Trump suggesting that Washington could review its longstanding neutral position on the Falklands. Milei welcomed the possibility, saying the “winds of change” favoured Argentina’s claim.
The renewed tensions have brought the longstanding Falklands dispute back into international focus, particularly as Argentina increases pressure over offshore oil development and Britain maintains its commitment to the territory and its residents.
