On the afternoon of October 11, 2025, a delegation from the Bureau International des Expositions (BIE) visited the Expo Museum pavilion at the Osaka Expo. As the intergovernmental organization responsible for overseeing World Expos, the BIE invited representatives including ambassadors from some of its member states stationed in Japan to tour the Osaka Expo.

　　This visit, as a key part of the BIE Day itinerary, specifically included a tour of the Expo Museum Pavilion—the only official museum of the Bureau International des Expositions. The event was attended by BIE Secretary General Dimitri S. Kerkentzes and BIE President Alain Berger. Expo Museum Director Liu Wentao accompanied the delegation, providing introductions to the exhibits. The representatives showed great interest throughout the tour.
