South Korean President Lee Jae Myung has embarked on a diplomatic tour spanning Brazil, Chile, and Argentina, with officials in Seoul describing the trip as central to the country's efforts to secure stable access to critical minerals. The visit comes as demand for rare earth elements and other resources essential to artificial intelligence and semiconductor production continues to climb, putting pressure on governments to lock in reliable suppliers before shortages bite.

The itinerary reflects a deliberate recalibration of South Korea's approach to the region. For decades, the relationship followed a familiar pattern: South American nations supplied raw materials, and South Korea returned finished manufactured goods. Officials travelling with the president have indicated that this model is being replaced by one built around joint value creation, in which processing, technology transfer, and industrial development happen closer to the source of the resources themselves.

The rationale rests on complementary strengths. Brazil, Chile, and Argentina hold substantial reserves of lithium, copper, and other minerals, alongside significant agricultural and energy capacity. South Korea, meanwhile, has built its economy around advanced manufacturing, shipbuilding, battery production, and digital technology. Bringing these two sets of capabilities together, the argument goes, could produce more resilient supply chains and generate skilled employment on both sides of the Pacific, rather than leaving South America as a source of raw exports alone.

That logic has gained urgency amid a broader deterioration in the global trading environment. Protectionist measures have multiplied over the past few years, supply chains have proven vulnerable to disruption, and geopolitical tensions have made previously dependable trade routes less certain. For a country as dependent on imported raw materials as South Korea, this instability has sharpened the appeal of diversifying away from a small number of suppliers and toward partnerships governed by clearer, more predictable rules. Energy security in particular has become a preoccupation for Seoul, which imports the overwhelming majority of its energy needs and has few domestic alternatives to fall back on.

The tour's agenda includes bilateral summits with the heads of state in each country, alongside a push to deepen ties with the Mercosur trading bloc, which groups Brazil and Argentina among its members. Officials see Mercosur as a route to broader access across the region rather than a series of separate bilateral arrangements negotiated one country at a time.

Chile occupies a particular place in these discussions. South Korea and Chile signed a free trade agreement in 2004, one of Seoul's earliest such deals and a template for many that followed. Two decades on, negotiators are working to modernise the treaty to reflect areas of trade that barely existed at the time it was signed. Digital trade provisions, environmental cooperation, labour standards, and gender equality have all been flagged as priorities for the updated agreement, alongside broader commitments to innovation. The update is being watched closely by trade officials elsewhere in the region, some of whom regard it as a possible model for their own agreements with Seoul.

Whether the trip produces binding commitments or simply a framework for future negotiation remains to be seen. Trade agreements of this scope typically take years to finalise, and the specifics of mineral access, investment terms, and technology sharing will require considerably more detailed negotiation than a single tour can accomplish. Still, officials in Seoul are framing the visit as the start of what they call a new phase in relations with South America, one intended to be less transactional and more durable than the arrangements that preceded it. If it holds, the shift would mark a meaningful departure from the raw-materials-for-manufactured-goods pattern that has defined the relationship since South Korea first began investing in the region decades ago.
