At 4:46 p.m. on May 16, His Majesty the King and Her Majesty the Queen journeyed to Wat Prachaniyom in Muang Kalasin District, Kalasin Province, to preside over the ceremonial cornerstone laying for the ordination hall. Upon arrival, Deputy Governor Thanaphat Na Ranong and provincial officials received the royal procession. The King entered the sanctuary, lit incense and candles in reverence to Buddha Nawarat, took the precepts with the monastic leadership officiating. After receiving a royal audience, the provincial governor reported on the history of the Si Ming Muang Chedi construction project and requested the King's presence at the cornerstone ceremony.

The King and Queen then proceeded to the ceremony site, where they wore ceremonial garments, applied gold leaf to the cornerstone, performed the ritual laying, and scattered coins into the foundation pit as monks chanted auspicious verses. After placing a commemorative plaque, the royal couple returned to the sanctuary to present Thai four requisites to the monks and bestowed alms. During the ceremony, Phra Thammavichit (Bua Sri Chutindharo), advisory abbot of Wat Prachaniyom, presented the King and Queen with a brass Buddha image inscribed with "Celebrating the Chedi 2569" as a commemorative gift.

Following the ceremony, the King and Queen traveled by helicopter to Roi Et Airport in Roi Et Province before departing by airplane for Bangkok. The occasion drew large crowds from Kalasin and neighboring provinces who came to pay respects and express their loyalty. With royal permission, the Kanjanabarm Foundation, the Royal Medical Corps, and local hospitals set up screening units for breast cancer and cervical cancer to serve at-risk and disadvantaged women and attendees.

Surin held its first grand merit-making ceremony at the sacred Khana Prasat on May 15, 2025, at 8:30 a.m., organized by Kab Choeng District officials, Naeng Moo Subdistrict Administration, and local residents following the December 2024 border conflict in which Thai troops pushed Cambodian forces out of the area.

Deputy Governor Prabhas Srijuntuaviang presided over the ceremony, which drew over 300 classical dancers and numerous visitors from both the local area and beyond. Attendees toured the Khana Prasat site located on the Phanom Dong Rak ridge along the Thai-Cambodian border south of Naeng Moo village in Kab Choeng District, Surin Province.

The Khana Prasat was discovered by Border Patrol Police Unit 216 and reported to the Fine Arts Department's Nakhon Ratchasima office, which conducted surveys in September 2001. The survey revealed a three-building brick temple with an eastern entrance, surrounded by laterite stone walls measuring approximately 39.50 meters per side. The structure shows signs of deterioration, with scattered architectural fragments including octagonal doorframe columns and carvings of three-headed elephants, seated figures, and Shiva lingams with visible Vishnu elements.

Based on archaeological evidence, Khana Prasat is believed to be a Hindu sanctuary constructed around the 15th Buddhist century—approximately 1,100 years ago—representing an important archaeological site demonstrating ancient human settlement in the Phanom Dong Rak ridge area of Lower Northeast Thailand.

Today's ceremony included merit-making at the temple and laying wreaths at a monument honoring soldiers who gave their lives protecting Khana Prasat. Local residents and visitors expressed pride in Thailand's military recovery of the site and pleasure that the Fine Arts Department has officially registered Khana Prasat as a Thai archaeological monument. Attendees photographed the area and the views overlooking the Cambodian side as souvenirs.

Thailand's windsurfing team is using the 2026 IQ Foil European Championship in Portimão, Portugal (May 16-23, 2026) to test competition systems against Asian Games rivals from Japan, China, and Hong Kong, with goals of placing athletes in the gold fleet (top half rankings). The six-member Thai team—Nittipat Chaiyawutwet, Siriporn Kaewduanggam, Vachirawit Tanuap, Vachirawit Manbuamrung, Ratchananon Khunjeng, and Chanatakan Charoensouk—arrived early on May 4 for training under coaches Natthapong Potinpratton and Sakda Skulfang.

According to Pattana Bunsawat, secretary of the Thai Windsurfing Association, the team initially faced stormy weather upon arrival but subsequently conducted intensive sea training once conditions improved with moderate winds and calm waves. All Thai athletes are performing well in these conditions.

The competition serves as a critical test against Japan, China, and Hong Kong competitors ahead of the 20th Asian Games in Nagoya, Japan (September 19-October 4, 2026). The open-category athletes aim for top placements while youth competitors focus on building strength and gaining experience from international-level athletes.
