Overview
- Foreign Minister Pablo Quirno made the announcement during the CARI annual dinner, publicly accusing the United Kingdom of refusing negotiations and saying Argentina will seek arbitration under the United Nations Convention on the Law of the Sea to challenge British activities.
- Quirno reaffirmed that Argentina is enforcing administrative, penal and regulatory measures against companies operating without Argentine authorization in waters around the Malvinas and defended those sanctions as part of a peaceful strategy to protect national rights.
- The British ambassador in Buenos Aires, David Cairns, attended the event, took notes and left saying he would inform his government, and reporters said the Chilean ambassador also departed early after the speech.
- Quirno cited immediate market and corporate effects he attributes to Argentina’s measures, including Halliburton’s reported withdrawal from Sea Lion services and sharp share drops at firms tied to the Sea Lion project such as Rockhopper and Navitas.
- The move internationalizes the decades‑old sovereignty dispute over the Malvinas and the nearby Sea Lion oil prospects, raising the prospect of prolonged arbitration, further diplomatic frictions and possible consequences for regional trade and energy projects.
