**Deck**: Argentina’s President Javier Milei has announced measures against companies working in the Malvinas/Falklands without Argentine permission, while Chile’s President José Antonio Kast backed Argentina’s sovereignty claim in a joint statement that also affirmed Chilean control over the Strait of Magellan.

Argentina and Chile have taken coordinated political steps on long‑sensitive territorial questions, with Buenos Aires announcing measures against companies operating in the Malvinas/Falklands and both governments reaffirming their respective positions on the islands and the Strait of Magellan.

In a national address, Argentine President Javier Milei outlined a series of decisions concerning companies that operate in the Malvinas without authorization from Argentine authorities. The available reporting says these measures follow months of work among different government areas and are framed as part of a policy focused on what Argentina describes as its sovereignty in the islands.

Separately, after a meeting in Santiago, Milei and Chilean President José Antonio Kast issued a joint communiqué in which Chile backed Argentina’s sovereignty claim over the Malvinas. In the same statement, both governments recognized that the Strait of Magellan is Chilean, and they described the overall state of bilateral relations as excellent.

For firms active around the islands, new Argentine measures raise potential legal and commercial complications. Argentina has long opposed activities it views as bypassing its authority in the area, and additional steps could increase pressure on companies to choose between Argentine regulations and arrangements linked to the islands.

Regionally, the joint statement signals alignment between Argentina and Chile on how they view control over the islands and a key southern maritime passage. This shared position could shape debates in international forums and influence how other states and companies approach operations in the South Atlantic and in waters near the Strait of Magellan.

Developments to watch next include the publication of detailed Argentine measures against targeted companies, any follow‑up Chilean actions in regional or global organizations, and official responses from other governments involved in the Malvinas/Falklands dispute, which will show whether this marks a symbolic reaffirmation or the start of a more sustained diplomatic campaign.
