BUENOS AIRES — South Korea and Argentina agreed Friday to strengthen their bilateral cooperation on critical minerals, including by pursuing joint projects across the entire lithium value chain, a presidential official said Friday.

A memorandum of understanding (MOU) toward that end was signed on the sidelines of a bilateral summit between South Korean President Lee Jae Myung and his Argentine counterpart, Javier Milei, in Buenos Aires.

Under the MOU, the two countries will share information on their respective policies regarding critical minerals and related investment systems, while promoting bilateral corporate investment and pursuing joint projects across the entire lithium value chain, including exploration and mining, according to National Security Adviser Wi Sung-lac.

Seoul and Buenos Aires also agreed to cooperate to ensure stable exports of Argentine crude oil to South Korea, as South Korea plans to begin importing Argentine crude oil next year following a pilot shipment earlier this year, he said.
