Lee Jae Myung Wraps Up Five-Nation Tour With Frankfurt Stop

South Korean President Lee Jae Myung arrived in Frankfurt on Sunday for the final leg of a five-nation tour that began July 24 in San Francisco, before returning home to Seoul later the same day. The trip, which also took him to Brazil, Chile and Argentina, was built around three priorities that have come to define Lee's early foreign policy: securing critical mineral supplies, advancing artificial intelligence and semiconductor partnerships, and diversifying South Korea's global supply chains.

The tour opened in San Francisco, where Lee met with executives from major global technology firms to pitch South Korea as a future hub for AI semiconductor production. From there he traveled through South America, holding summits with the leaders of Brazil and Chile before arriving in Argentina, a country increasingly central to Seoul's resource strategy given its vast lithium reserves.

In Buenos Aires, Lee held bilateral talks with Argentine President Javier Milei that produced concrete commitments rather than broad statements of intent. The two leaders agreed to pursue joint projects spanning the entire lithium value chain, from extraction to processing, and to expand South Korea's imports of Argentine crude oil starting next year. They also pledged to push for a prompt resumption of stalled free trade negotiations between South Korea and Mercosur, the South American trade bloc.

Speaking to members of the South Korean community in Argentina ahead of his departure, Lee said cooperation between the two countries was entering a stage of "tangible results." He argued that shifting global supply chains made close bilateral ties "more important than ever," and said he was confident a new era of Korea-Argentina relations would take shape.

Frankfurt served as a lower-key coda to the trip. Rather than a formal summit, Lee's schedule there centered on a meeting with members of the Korean expatriate community in Germany, a gesture that has become a recurring feature of his overseas visits. He was expected to depart for Seoul later on Sunday, closing out a tour that spanned four continents in roughly ten days.

The trip underscores how quickly critical minerals and AI infrastructure have moved to the center of South Korea's foreign policy, as Seoul looks beyond its traditional trading partners to secure the raw materials and technology partnerships needed to compete in next-generation industries.
