- South Korean President Lee Jae-myung will travel to Mexico City sometime this month; President Claudia Sheinbaum hasn't locked in an exact date.
- The trip is expected to include the signing of a new five-year cooperation roadmap, the Mexico-Korea Action Plan 2026–2030, built on groundwork laid during Foreign Secretary Roberto Velasco's late-August trip to Seoul.
- Sheinbaum says an idol act "younger than BTS" is coming along too, but won't name it — Korean media are now floating Stray Kids as an early guess, not a confirmation.
Mexico City is bracing for a rerun of the scene that unfolded in May, when BTS packed the Zócalo with tens of thousands of fans. On September 3, President Claudia Sheinbaum told reporters at her morning briefing that her South Korean counterpart, Lee Jae-myung, will land in the capital sometime this month. He isn't coming just for trade talks: an idol group is joining the trip, and Sheinbaum isn't saying which one.
What Sheinbaum Actually Said
Speaking from the National Palace, Sheinbaum framed the visit around commercial, cultural and investment ties between the two countries, then added the detail that set social media buzzing. Asked about the purpose of the meeting, she said one of the K-pop acts coming to Mexico is "younger than BTS", promising more details "in the coming days." No date, no lineup, no name — just the tease, which caught even seasoned K-pop fans in Mexico off guard.
Strip away the pop-culture headline and this is fundamentally a commercial visit. South Korea counts more than 2,000 companies operating inside Mexico, and Sheinbaum's government has been building toward this trip through months of direct phone contact with Lee, according to officials. Related investment, education and cultural spending tied to the relationship has reportedly topped $2.6 billion this year, per El Dictamen — though that specific figure hasn't turned up independently in other outlets' reporting, so treat it as a single-sourced estimate rather than a confirmed total.
A Five-Year Roadmap Nobody's Talking About Yet
The part of this story that's gotten the least attention so far may end up mattering the most. Foreign Secretary Roberto Velasco spent August 23–25 in Seoul meeting Korean Foreign Minister Cho Hyun, and the two sides used the trip to finalize plans for what officials are calling the Mexico-Korea Action Plan 2026–2030 — a formal bilateral roadmap both governments intend to sign once Lee arrives in Mexico City. Velasco has also floated a Korean cultural center opening in Mexico, part of a wider push on AI, digital governance and aerospace cooperation between the two countries.
The Bar BTS Set in May
Whoever is traveling with Lee inherits a tough act to follow. When BTS visited the National Palace on May 6 ahead of three sold-out shows, roughly 50,000 fans packed the Zócalo to watch the group greet them from a balcony beside Sheinbaum. Member RM addressed the crowd in Spanish and English, telling them "we can't wait for tomorrow's concert on stage" before the band's run at Estadio GNP began.
That visit wasn't purely celebratory — it grew out of a mess. Demand for BTS tickets badly outstripped supply months earlier, triggering scalping complaints so severe that Sheinbaum personally wrote to Seoul asking for additional dates, while Mexico's consumer protection agency, Profeco, opened enforcement action against resale platforms and Ticketmaster. The May visit doubled as a thank-you gesture: BTS was later named a distinguished visitor by the Mexican government, and received formal recognition for the honor weeks afterward. Sheinbaum has since said the group has already agreed to come back to Mexico sometime in 2027.
Is It Stray Kids? The Guessing Game Heats Up
Sheinbaum's silence has fans doing detective work, and one name keeps surfacing. Stray Kids — whose members skew younger than BTS's lineup — already has its own Mexico City stop booked for September 25 and 26, and member Felix attended an official diplomatic event alongside Lee earlier this year during French President Emmanuel Macron's state visit to Seoul, fueling speculation about a connection. Other fans are betting on Aespa or Winner instead. None of these names has been confirmed by either government, and it's entirely possible the act turns out to be someone nobody's guessed yet.
Don't Confuse This With K-Expo México
One event on the calendar is already locked in and has nothing to do with the presidential trip: K-Expo México 2026, a free public exhibition running September 25–27 at the WTC convention center, with business-focused days starting September 24. It closes with the Korea Spotlight concert on September 26 at Pepsi Center WTC, featuring Winner, Dayoung, Soyou and Touched. That lineup was announced independently of Lee's visit, and organizers haven't tied it to the presidential delegation.
What Happens Next
For now, only two things are locked in: the month, and the pairing of a sitting South Korean president with an idol act nobody will name. Sheinbaum has promised a name, a date and a full itinerary "in the coming days" — leaving diplomats watching for a trade roadmap and K-pop fans watching for a lineup announcement, off the same headline for very different reasons.
