South Korean President Lee Jae-myung is wrapping up an extensive 11-day diplomatic tour across North America, South America, and Europe, marking the longest overseas trip of his 14-month presidency. Since taking office in June 2025, Lee has sought to diversify South Korea's diplomatic and trade relations beyond traditional partners like the United States, China, and Japan through a strategy the presidential Blue House terms "Global South diplomacy."
The multi-nation tour commenced on July 24 in San Francisco, where President Lee held individual meetings with prominent tech leaders, including Nvidia CEO Jensen Huang, OpenAI CEO Sam Altman, Anthropic CEO Dario Amodei, and Broadcom President and CEO Hock Tan. According to Lee's policy chief, Kim Yong-beom, these discussions were designed to bolster South Korea's three flagship megaprojects: a state-led investment initiative targeting semiconductors, artificial intelligence data centers, and physical AI. The following day, during the San Francisco AI Summit on July 25, Lee presented the "San Francisco Declaration on AI," promising that South Korea "will become a trusted production base and supply-chain partner for AI chips" to guarantee a stable supply chain despite global shortages.
From California, Lee traveled to Brazil on July 26 for a state visit at the invitation of Brazilian President Luiz Inácio Lula da Silva. This marked Lee's fifth meeting with Lula and the first state visit by a South Korean leader to Brazil since Park Geun-hye's visit in 2015. On July 27, the two leaders held a summit at the Alvorada Palace, signing a joint statement that designated 2026 as the founding year of an upgraded strategic partnership. They also signed seven memoranda of understanding (MOUs) covering industrial technology, space, energy, sports, education, film, and cybersecurity. Crucially, the leaders agreed to establish a joint working group to restart long-stalled negotiations on the Korea-Mercosur trade agreement by December. Mercosur, which comprises Brazil, Argentina, Paraguay, and Uruguay, represents a critical market, and Brazil itself holds the world's second-largest reserves of rare earth elements at approximately 21 million tons.
Lee's diplomatic push continued in Santiago, Chile, where he arrived on July 29, becoming the first South Korean president to visit the country in 11 years. On July 30, Lee and Chilean President Jose Antonio Kast held a joint press conference, agreeing to reactivate the South Korea-Chile Free Trade Commission for the first time in ten years and modernize their existing 2004 free trade agreement. To secure vital resources, the two governments signed five MOUs addressing transnational crime and critical minerals. This partnership elevates their joint minerals committee to a ministerial level, aiming to secure copper and lithium supply chains valued at roughly $2.1 billion annually.
The next leg of the tour brings Lee to Buenos Aires on July 31, marking the first bilateral visit by a South Korean president to Argentina in 22 years. Following a wreath-laying ceremony at Plaza San Martín, Lee is scheduled to meet with Argentine President Javier Milei at the Casa Rosada presidential palace. Seoul officials stated that the summit will focus on establishing a supply chain partnership around lithium—of which Argentina holds the world's fourth-largest reserves—alongside cooperation in energy and food security. Together, Brazil, Chile, and Argentina represent a combined market of 280 million people with a joint GDP of $3.7 trillion, equivalent to the world's seventh-largest economy. President Lee will conclude his trip in Frankfurt, Germany, meeting with the local Korean community on August 2 before returning to Seoul on August 3.
