Core Event: UN General Assembly keynote and bilateral summit with Mexico
South Korean President Lee Jae Myung will travel to the United States and Mexico from September 21 to 27 to attend the United Nations General Assembly (UNGA) in New York and to conduct a state visit with Mexican President Claudia Sheinbaum. On September 22 he is scheduled to deliver a keynote address on UN reform and a blueprint for peaceful coexistence on the Korean Peninsula, after which he will meet UN Secretary-General António Guterres. The following day he will fly to Mexico City, where a series of ceremonies—including a wreath-laying at the Altar a la Patria, an expanded summit, and the signing of memoranda of understanding—are slated for September 24. The itinerary concludes with a business forum at the World Trade Center on September 25 and his departure for Seoul on September 26.
Background & Context
Lee’s trip marks his second appearance at a high-level UNGA session, following a debut the previous year. The Blue House has highlighted that the visit coincides with ongoing negotiations on a $350 billion South Korean investment package in the United States, a component of the trade deal struck by the two allies in 2025. The Mexico state visit is the first by a South Korean president in 16 years, reflecting a renewed emphasis on trade, energy, aerospace, and cultural exchange. Mexico is identified as South Korea’s largest market for K-pop, and both sides see opportunities to deepen defence cooperation as Mexico modernises its military.
