U.S. delegation advances $7 billion Andes-Atlantic Corridor framework in Argentina with lithium and energy focus

The U.S. delegation arrived in Argentina on October 5 to evaluate investment opportunities tied to the Andes-Atlantic Corridor, a bilateral initiative estimating up to $7 billion in potential financing for projects connecting Argentine production zones with Atlantic ports. The mission includes representatives from the State Department, the Export-Import Bank, and the Development Finance Corporation. Ambassador Peter Lamelas received the delegation, which is led by Katrien Hinderdael, director of Global Infrastructure and Investment at the State Department, alongside Danielle Monosson from the Office of Brazil and Southern Cone Affairs, Ryan Berg from DFC, and Carter Mateer from EXIM.

Foreign Minister Pablo Quirno met the delegation at Palacio San Martín on October 6 to discuss implementation steps for the corridor framework, which Quirno and U.S. Undersecretary of State Christopher Landau presented in New York on September 23. The initiative targets modernization of transport, energy, mining, and technology infrastructure to improve connectivity between Argentine productive regions and international markets. The $7 billion figure represents potential investment capacity rather than committed disbursements, with the mission tasked to identify viable projects and assess financing mechanisms.

Jujuy province features prominently in the agenda, with the delegation participating in activities tied to lithium and critical minerals development. Hinderdael is scheduled to speak at a panel analyzing the strategic relationship between Argentina and the United States, focusing on supply security for critical minerals, financing opportunities, and building commercial alliances amid fragmented international supply chains. The event addresses conditions for promoting investment, developing infrastructure, and expanding value-added processing within Argentina’s mining sector.

Lithium represents a priority resource due to its role in battery production and energy storage systems. The corridor framework contemplates integrating Argentina’s northwestern mineral reserves, including lithium and copper deposits, with Vaca Muerta hydrocarbon development in Neuquén and Atlantic port terminals. Proposed investments span railways, pipelines, waterways, port infrastructure, and electrical transmission networks. Specific projects under consideration include upgrades to Belgrano Cargas freight rail, the Hidrovia waterway system, and potential rail connections linking Vaca Muerta with Bahía Blanca port.

Of the $7 billion financing framework, approximately $6 billion relates to Argentina LNG, the liquefied natural gas export project developed by YPF, Italy’s ENI, and UAE-based XRG. EXIM is evaluating a potential financing package for that project, with support mechanisms including loans, guarantees, and insurance instruments. The broader corridor initiative also encompasses telecommunications, fiber optics, and digital systems alongside mineral and energy infrastructure.
