Argentina begins sanctions process against 45 entities exploring Falklands

Argentina, on Friday (4/9), began the process of imposing sanctions against 45 individuals and companies suspected of conducting hydrocarbon exploration and exploitation without permission in the Falkland Islands, a territory referred to by Buenos Aires as the Islas Malvinas.

The office of President Javier Milei announced that the legal action targets not only the operating oil companies but also “shareholders as well as companies providing services” to facilitate these operations.

The government stated that parties attempting to profit by violating Argentine sovereignty “will face the full force of the law of the Argentine State.”

The government reaffirmed its claim over the Falkland Islands, South Georgia, and the South Sandwich Islands, along with the “related maritime and island territories,” asserting that these areas belong to Argentina “both historically and legally” and that this status is “inviolable.”

Previously, Milei warned that the Sea Lion oil project—a large-scale offshore hydrocarbon development near the Falklands operated by the British company Rockhopper Exploration and the Israeli company Navitas Petroleum—represents a real and urgent threat.

He stated that without swift action, foreign entities would “take control of the oil reserves beneath our seas” and deepen their “occupation.”

London has dismissed the sanctions as a domestic political move and reaffirmed its commitment to the islands, while Navitas and its partners have stated they will continue drilling under British licences.

The long-standing sovereignty dispute between Buenos Aires and London has intensified as offshore projects move towards the active drilling stage.

The Falklands is a British Overseas Territory in the South Atlantic, located approximately 483 kilometres east of the Argentine coast, with a small population.

Argentina argues that it inherited sovereignty from Spain and that the United Kingdom has “illegally occupied” the islands since 1833; the country refers to the islands as the Islas Malvinas and refuses to recognise the self-determination of the local inhabitants as a deciding factor.
