Buenos Aires province minister Carlos Bianco says Milei acted late and opportunistically against Sea Lion
Carlos BiancoMinister of Government of Buenos Aires province, in a post on X
Carlos Bianco, minister of government of Buenos Aires province, said President Milei had taken 267 days from the Sea Lion partners' December 2025 investment decision to apply the law and was now doing so opportunistically. He said Argentina already had a legal tool in Law 26,659, that Milei had taken no effective measure against the project in the meantime, and that he and his allies are working for Argentina to raise the costs of what he called the British occupation from December 2027.
“It took the Thatcher fan 267 days to comply with the law. Now he does it opportunistically. All that time has passed since Navitas and Rockhopper announced, on December 10, 2025, their final decision to invest in the illegitimate exploitation of Sea Lion, in the North Malvinas Basin. (Translated from Spanish. Original: 267 días tardó el fan de Thatcher en cumplir la ley. Ahora lo hace de manera oportunista. Todo ese tiempo transcurrió desde que Navitas y Rockhopper anunciaron, el 10 de diciembre de 2025, su decisión final de invertir en la explotación ilegítima de Sea Lion, en la Cuenca Malvinas Norte.)”

Where this statement fits
Should Argentina sanction UK and Israeli oil companies exploring near the Falkland Islands?
On September 3, 2026, Argentine President Javier Milei announced plans to sanction companies involved in oil exploration near the Falkland Islands, which Argentina calls the Malvinas and has long claimed from Britain. He called the Sea Lion oil project, operated by UK-based Rockhopper Exploration and Israel's Navitas Petroleum, a "concrete and urgent danger." Argentina has since filed a criminal complaint against Navitas Petroleum, begun sanctions proceedings against 60 companies and individuals connected to the project, and a Tierra del Fuego court has ordered the companies to suspend Sea Lion activity pending an environmental review, a step reported as largely symbolic since the project operates under Falkland Islands government licenses. Rockhopper and Navitas say they hold valid licenses with the UK's support and do not expect the measures to affect their activities. UK Foreign Secretary Ed Miliband called the UK's position on the islands "unwavering." Milei has tied the escalation to a 1976 UN resolution against unilateral action and has also announced funding for a new Argentine naval base in Tierra del Fuego. The dispute is whether Argentina should sanction and seek to block companies exploring for oil near the Falkland Islands.

How this statement is classified
The label describes this statement's response within the context above.
Why this label?
Relative to Argentina's sanctions and legal action against companies in the Sea Lion project, Bianco treats action against the project as what Argentine law already required and wants it to go further, while calling Milei's move late and opportunistic. He backs the aim but criticizes the government's timing and motives, so we labeled it Mixed.

International law professor Donald Rothwell says Argentina's Sea Lion case "could therefore fall at the first hurdle"
“While Argentina has framed its claim around UNCLOS, the core of the case is the territorial dispute over the islands, referred to as Malvinas by Argentina. ... Argentina's claim could therefore fall at the first hurdle, and Buenos Aires is no doubt aware of this challenge.”Read statement
Liberal Democrat Al Pinkerton calls Milei's use of UNCLOS arbitration "neo-colonialism dressed up as anti-colonialism"
“They spoke for themselves as a self-governing, self-determining, distinct and identifiable people, yet President Milei now seeks to use UNCLOS arbitration to deny the islanders of economic sovereignty and the right to shape their own future. That is neo-colonialism dressed up as anti-colonialism.”Read statement
