BIGBANG is celebrating its 20th anniversary with the announcement of the 'XX : COSMOS World Tour' set for 2026–2027, featuring stops in major Asian cities and a free fan event on Seoul's Han River. The group is also set to release a new song for the first time in four years, following the rapid sell-out of their Goyang concert tickets and the unveiling of tour details. G-Dragon has been appointed as an ambassador for the 48th UNESCO World Heritage Committee, while members Daesung and Taeyang have drawn attention for public gestures toward fans and former group members.
