Activists rallied at the Plaza de La Liberación in Guadalajara, Mexico, ahead of the Group A World Cup fixture between Mexico and South Korea, calling out tournament sponsor Hyundai for its alleged links to a "dirty steel supply chain." A 2025 report by environmental group Mighty Earth accused Hyundai of purchasing iron ore from Latin American steelmaker Ternium, a company facing longstanding criticism over environmental damage and its alleged connection to the 2023 disappearance of two Mexican activists — human rights lawyer Ricardo Arturo Lagunes Gasca and Indigenous community leader Antonio Díaz Valencia — who went missing after attending an anti-mining meeting in Aquila, Michoacán. Protesters accused Hyundai, an official FIFA mobility partner supplying nearly 1,500 vehicles across the tournament's three host countries, of sportswashing, while Ternium categorically denied any involvement in the disappearances and Hyundai declined to comment.
