UK minister Uma Kumaran calls Argentina's arbitration "the latest attempt to undermine the rights and livelihoods" of Falkland Islanders
Uma KumaranUK Parliamentary Under-Secretary of State responsible for the Overseas Territories, in a statement posted on X
UK Overseas Territories minister Uma Kumaran said Argentina's decision to open arbitration under the UN Convention on the Law of the Sea was the latest attempt to undermine Falkland Islanders' rights and livelihoods. She said hydrocarbon activity on the islands' continental shelf follows Falkland Islands law and international law, that the UK had told Argentina's ambassador its efforts to obstruct lawful economic activity were deliberate attempts to undermine the islanders, and that this raised questions about Argentina's reliability as a partner.
“Argentina's decision to initiate arbitration against the United Kingdom under the United Nations Convention on the Law of the Sea (UNCLOS) is the latest attempt to undermine the rights and livelihoods of the people of the Falkland Islands.”

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.

Before the quotation
Kumaran posted the statement two days after Argentina announced arbitration against the UK under Annex VII of the UN Convention on the Law of the Sea over the Sea Lion project.
After the quotation
She continued that islanders "have every right to develop and manage their natural resources without intimidation, coercion or interference from others," that the UK had told Argentina's ambassador that "efforts to obstruct lawful economic activity in the Falkland Islands are not acts of responsible international engagement," and that "Such behaviour raises questions about Argentina's reliability as a partner for the United Kingdom."

Why this label?

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
