Bangkok, 9 December 2025 — Thailand marked its triumphant return as SEA Games host with a spectacular Opening Ceremony at Rajamangala National Stadium, uniting the region under the theme “We Are One — We Are Connected by the Sea.”

Presided over by His Majesty King Maha Vajiralongkorn and Her Majesty Queen Suthida, the event blended royal tradition, cultural heritage, and modern entertainment, creating an unforgettable night for Southeast Asia. This successful hosting further strengthens Thailand’s ambition and readiness to host the Youth Olympic Games in 2030 if elected. 

Royal Presence Inspires the Region

In his opening address, His Majesty the King welcomed athletes and officials from all 11 nations, emphasizing friendship and brotherhood across Southeast Asia. Her Majesty the Queen made history by leading the Thai athletes’ procession as she prepares to compete in sailing.

Muaythai Shines on the Global Stage

A highlight of the ceremony was Buakaw Banchamek performing the sacred wai kru, symbolizing the respect, discipline, and tradition of Muaythai — a sport proudly rooted in Thai culture and shared throughout the region.

A Spectacle of Culture and Innovation

The ceremony featured:

  • A drone show forming the SEA Games emblem
  • A shimmering river-themed stadium floor linking the 11 nations
  • Performances by Violette Wautier, Twopee, F.Hero, and BamBam
  • A dramatic aquatic segment with jet skis and flyboard stunts
  • A star-studded torch relay, culminating with Olympic champion Panipak “Tennis” Wongpattanakit lighting the cauldron

A Moment of Integrity and Togetherness

Thai athletes Puripol Boonson, Banlung Tubtimdang, and Tanyaporn Prucksakorn delivered the Athletes’ Oath, reinforcing the values of fair play and respect that define the Games.

Athletes from all 11 nations marched proudly, with Thailand receiving a roaring welcome as host. A moment of remembrance honored the recent passing of Her Majesty Queen Mother Sirikit.

Muaythai Competition at Lumpini Stadium

Representing IFMA at the ceremony were Dr. Sakchye Tapsuwan, Stephan Fox, and Janice Lyn.
Muaythai events will be held 13–17 December at the historic Lumpini Stadium.

Dr. Sakchye reflected:

“The SEA Games celebrate unity and culture. Seeing Muaythai on this grand stage is a proud reminder of the values our sport brings to the world.”

A Night to Remember

The 33rd SEA Games Opening Ceremony celebrated the power of sport to unite nations and honor Southeast Asia’s shared cultural heritage. For Muaythai, it was a shining moment — a reminder that the art of eight limbs is truly Southeast Asia’s gift to the world and that Thailand stands ready to welcome the world again at the Youth Olympic Games in 2030.
