Milei Threatens Falkland Oil Firms With Sanctions

Argentine President Javier Milei has threatened sanctions against oil companies operating around the Falkland Islands, escalating Argentina’s long-running sovereignty dispute with Britain over the South Atlantic territory.

In a televised national address on Thursday, Milei said he would send Congress an urgent “national sovereignty defence” bill designed to strengthen penalties against companies conducting unauthorized activities near the islands, known in Argentina as Las Malvinas.

The proposed legislation would expand sanctions beyond oil operators to include shareholders, directors, suppliers and other entities linked to activities that Argentina considers a violation of its sovereignty or exploitation of its natural resources.

Milei’s tougher stance comes days after U.S. President Donald Trump said Washington was reviewing its traditionally neutral position on the Falkland Islands dispute. Trump also questioned whether Britain currently had the military capacity to defend the territory in another conflict.

Britain rejected Milei’s position. British defence minister Wes Streeting said the Falkland Islanders had chosen to remain British and described the UK’s commitment to the territory as “absolute and unshakeable.”

Britain has controlled the Falkland Islands since 1833. Argentina invaded the territory in April 1982, triggering a 74-day war that ended with British forces regaining control.

At the center of the latest dispute is the Sea Lion oilfield, located roughly 140 miles north of the Falkland Islands. The project is operated by Tel Aviv-listed Navitas Petroleum, while London-listed Rockhopper Exploration holds a 35% interest.

Development work at Sea Lion could begin within months. Rockhopper says the project contains an estimated 1.7 billion barrels of oil resources, making it potentially significant for future Falkland Islands oil production.

Rockhopper shares fell about 8% on Friday morning following Milei’s announcement. Neither Rockhopper nor Navitas Petroleum immediately commented on the Argentine president’s remarks.

Milei has previously emphasized diplomacy in pursuing Argentina’s Falkland Islands claim, but the proposed sanctions signal a more confrontational approach as energy exploration intensifies around the disputed territory.
