South Korea and Argentina agree to strengthen bilateral cooperation focused on critical minerals, energy, and trade during meetings in Buenos Aires on Friday. South Korean National Security Adviser Wi Sung-lac says the two countries sign a memorandum of understanding (MOU) aimed at enhancing information-sharing on critical-mineral policies and related investment systems, while promoting corporate investment and joint projects. The MOU includes efforts across the full lithium value chain, covering stages such as exploration and mining. The agreement also includes cooperation to support stable exports of Argentine crude oil to South Korea. South Korea plans to begin importing Argentine crude oil next year after a pilot shipment earlier this year, a step described as a way to diversify South Korea’s crude oil supply sources.

South Korean President Lee Jae Myung says the countries’ cooperation is entering a stage focused on tangible outcomes, expanding beyond earlier collaboration into areas including lithium-related critical minerals, as well as energy and infrastructure. The discussions take place alongside a bilateral summit between Lee and Argentine President Javier Milei, with reports also noting Lee’s broader South America tour centered on strengthening critical mineral supply chains and related cooperation.
