US Deputy Secretary of State Christopher Landau said in Buenos Aires on Thursday 22 October 2026 that Washington is watching a proposed Argentine law that could punish US companies over the disputed Falklands. President Javier Milei then received him at the Casa Rosada, the presidential palace, on Friday 23 October for about two hours.
The Falklands bill, formally the National Sovereignty Defence bill, would extend Argentine sanctions to firms that help oil work in the waters around the islands. The visit also showed how closely Washington backs Milei, since a US ambassador has offered up to US$20 billion in financing for US firms investing in Argentina before the end of 2027.
In Plain English
- Falklands or Malvinas: South Atlantic islands that the United Kingdom governs and Argentina claims.
- The bill: a sovereignty law that would replace a 2011 law and sanction those who exploit resources in the disputed waters without Argentine permission.
- Christopher Landau: the deputy to US Secretary of State Marco Rubio.
- Pablo Quirno: Argentina’s foreign minister.
- Peter Lamelas: the US ambassador to Argentina.
- Sea Lion: a planned offshore oil project north of the Falklands that Argentina wants stopped.
What Landau Said in Buenos Aires
Landau spoke at a joint press conference with Foreign Minister Pablo Quirno at the Palacio San Martín, the foreign ministry, on Thursday. “We are obviously looking at the interests of our companies,” he said, adding that it is natural for any country to be concerned and that Washington respects Argentina’s legislative process.
Quirno answered that the bill “is not against anyone in particular” and is meant to make companies choose between the Argentine mainland and what he called the illegitimate licences of the islands. Landau said the laws of Argentina are a matter for the Argentine authorities and, in a line only Infobae reported (our translation), that no other country in the world is so aligned with the United States.
Clarín had reported on Sunday 18 October that Washington was worried about the bill, and Quirno and the presidential adviser Santiago Caputo both rejected that report on social media. Landau then confirmed the concern at the Thursday press conference, as Clarín noted.
Why the Falklands Bill Worries Washington
The bill would replace a 2011 law with a wider regime and create a National Security Council, according to MercoPress. Its sanctions would reach not only companies working near the islands but also affiliates, shareholders, financiers and suppliers tied to oil work that Argentina has not authorised.
Infobae reported that Ambassador Lamelas passed on concerns of Washington and US companies about the sanctions chapter. A penalty on suppliers and shareholders can touch firms far from the islands.
Argentina launched sanctions proceedings in September against dozens of people and companies linked to Sea Lion, which Navitas Petroleum and Rockhopper Exploration operate, according to MercoPress. The International Tribunal for the Law of the Sea will hold a hearing on 10 and 11 November in Hamburg on Argentina’s request to halt the project.
British Prime Minister Andy Burnham told President Donald Trump on Friday about the “economic consequences” of Argentina’s measures, Downing Street said, as quoted by MercoPress. MercoPress added that Trump has said recently that the US position of neutrality on sovereignty is under review.
Changes Promised but Not Confirmed
After talks with allied lawmakers and the American Chamber of Commerce in Argentina, the government promised changes to the text, Infobae reported on Friday. Under that plan the sanctions would be limited to direct operators, licensees, suppliers and direct shareholders of illegal projects, which would spare indirect investment funds.
The government has not confirmed that part, and on Saturday Infobae wrote that the Casa Rosada would not say whether the effect on associated companies will change. Officials said the changes agreed on Friday would not be substantial, while edits are expected to the chapter on penalties for press publications with “foreign interference”.
A joint committee meeting is set for Tuesday 27 October, and the governing bloc says it is close to a committee report. The government wants the lower house to pass the bill before the end of October, which depends on that report.
The Money Behind the Visit
On 20 October, Ambassador Lamelas said at an energy forum that US agencies, including the Export-Import Bank and the Development Finance Corporation, would put up to US$20 billion behind US companies investing in Argentina before the end of 2027. Infobae noted that this is almost three times the US$7 billion the two governments agreed in September.
Lamelas said the money would be ready until 2027 and that Washington would “see what happens after”, and he said Argentines should choose the path of the right and not the left. Quirno said both governments share an interest in Milei’s re-election next year, but that the only condition is to keep Argentina’s growth, macroeconomic order and fiscal balance.
Asked by Infobae about Lamelas’ remarks, Landau avoided them, Infobae reported. He spoke instead of the “enormous possibilities” of the country.
Quirno announced US grants of US$13 million for anti-drug programmes, of which US$7.5 million is for Argentina, and a child-protection pact worth up to US$10 million. He also announced US$15 million for a cybersecurity operations centre and a framework with the US Export-Import Bank to explore up to US$7 billion of financing for the Andes-Atlantic Corridor, a plan to link Argentina’s mining northwest and the Vaca Muerta energy basin to Atlantic ports.
Trade, Visas and the UN Angle
Quirno said Argentine exports to the United States reached US$6.57 billion from January to August, up 35% from a year earlier. He added that Argentina is negotiating entry into the US Visa Waiver Program, which would let citizens visit without a visa, but gave no date.
Both governments are preparing a visit by Vice President JD Vance in November, Clarín reported. Quirno also pointed to an additional protocol to the reciprocal trade and investment agreement, signed in Washington last week with US Trade Representative Jamieson Greer, as covered in Argentina Trade Deal Gets a US Rewrite.
Landau defended the US proposal to dissolve the UN Decolonisation Committee, where Argentina presents its Falklands claim each year, as part of a wider reform of the United Nations. Quirno called the claim non-negotiable and said the committee’s disappearance would not weaken it, after Argentina abstained on two of 23 decolonisation drafts on 15 October for what he called technical reasons.
What It Means for You
For US energy, shipping and finance firms, the question is whether the final text reaches suppliers, shareholders and financiers far from the islands. Any firm that deals with oil operators near the Falklands should watch the wording that comes out of committee on 27 October.
For investors in Argentine assets, the visit shows US backing that is large but tied to politics, since Washington’s ambassador links future money to the 2027 election. Our guides Argentina Explained, Who Dominates Argentina and Argentina Foreign Powers and Investors cover the players.
Visitors to Argentina see no immediate change, since the bill is still in committee. Our Buenos Aires expat city guide covers daily life, and our report Argentina Delays Malvinas Sovereignty Bill tracks the timetable.
What Is Not Known
It is not known whether the final text will exempt affiliates and indirect investors, because the government has confirmed changes only in general terms. The committee meeting on 27 October should show the wording.
The sources reviewed do not describe what Milei and Landau agreed in their two-hour meeting. It is also unclear how the up to US$20 billion would be allocated or what happens to it after 2027.
Washington has not said whether it will ask for specific changes, and Landau stressed that the US respects the legislative process. The Hamburg hearing on 10 and 11 November and the UK-US talks on Sea Lion may add pressure, but no outcome is known.
The US State Department’s own transcript could not be opened for this article. The quotes rest on Infobae, Clarín and MercoPress, which agree on the main points.
What Prediction Markets Say
Polymarket, an online prediction exchange, priced a UK announcement of a Falklands sovereignty transfer to Argentina by 31 December 2026 at 4.3% on 24 October, 5:10 a.m. ET. The market has traded about US$27,291 in total volume.
These are bets, not polls, and the price is far below even odds. On the platform’s own data it moved 2.5 percentage points higher over the past week.
Why we show this: prediction markets turn real-money bets into a live probability that moves within minutes of the news, which is why investors, campaigns and newsrooms in the United States now follow them closely. We show them next to polls and official results, never instead of them.
