On May 20, 2025, Chalermphong Saengdee, a Phuket MP from the Pheu Thai Party, posted on Facebook that a Royal Forest Department official involved in the illegal issuance of a land title for Freedom Beach in Phuket was dismissed from service but continues to receive pension payments and no criminal charges have progressed. The Ministry of Natural Resources and Environment issued an order terminating the senior official's employment over unauthorized aerial photo analysis that facilitated illegal land title issuance at Freedom Beach in Phuket, a matter Chalermphong said he had already raised in Parliament. Chalermphong noted that despite years passing since the incident, no criminal case has been filed against the former official, who still receives 67,560 baht monthly. Beyond the Freedom Beach case, the same individual also provided false aerial photo analysis of Koh Kradan in Kantang District, Trang Province, within Khao Sam Roi Yot National Park, contradicting actual facts. According to ministry orders, both cases resulted in dismissal with instructions for the Royal Forest Department to pursue criminal charges. Chalermphong stated that these orders date back to 2558 BE (2015), with 11 years having passed, and called for urgent action against the wrongdoer and involvement from state agencies such as the Anti-Corruption Commission (ACC) and National Anti-Corruption Commission (NACC). "I urge the public to follow this case," Chalermphong said. "The person must be punished, but merely being dismissed from service while still receiving pension is not justice. Without criminal prosecution, this constitutes unfair advantage taken against the nation and its people."

The Director-General of the Department of Local Administration signed orders reassigning Phuket's provincial deputy governor, five district officers, and other officials to other positions to open an investigation following complaints from entertainment business operators about alleged bribery demands. On May 20, 2569, Nurichaa Kosasivilai issued the transfer orders to ensure a rapid, transparent, and fair investigation process for all involved parties.

The action was prompted by social media reports of complaints from residents and entertainment venue representatives in Phuket province, which could damage the Interior Ministry and Department of Local Administration's image and public confidence in government. The Patong Beach Entertainment Business Association previously held an evening rally on May 13 to oppose extortion demands and call for fair licensing resolution and investigation processes, displaying signs condemning high-ranking provincial administrative officials.

On that same day, Weerwichaya Krueasombat, chairman of the Patong Beach Entertainment Business Association, and his delegation met with Prime Minister Anusit Charnveerakul during his official visit to investigate encroachment on Nakkhikhao National Reserved Forest and the Freedom Beach land case. The week prior, Nurichaa had summoned all involved officials for clarification before issuing today's urgent orders.

The transfer orders, Department of Local Administration Order No. 1512/2569 dated May 20, 2569, are effective from May 25 to June 24, 2569, and assign five officials: Rung Reueang Thimabut (Phuket Provincial Deputy Governor) to the College of Local Administration; Siwat Ravankul (Phuket City District Officer) to the Local Administration Management Office; Wilailik Reungphon (Thalang District Officer) to the Planning and Academic Affairs Division; Akkrapol Sutthirak Jitsupap (Kathu District Officer) to the Communications Division; and Danai Suksukol (Phuket Provincial Protection Officer) to the Department Secretary's Office.

The historic exhibition 'La Mode en Majesté: Royal Thai Dress from Tradition to Modernity' is now open at the Musée des Arts Décoratifs in Paris, France, from May 13 to November 1, 2025.

In 1960, when King Bhumibol Adulyadej made an official state visit to the United States and European countries, Queen Sirikit conceived the idea of developing the 'Royal Thai Dress' as Thailand's national costume for women. Observing that despite Thailand's beautiful and distinctive clothing culture, there was no clearly defined national dress recognized on the international stage, the Queen incorporated Thai silk and traditional local fabrics rooted in local wisdom, designing them with contemporary elegance. This became a crucial model for promoting Thai identity to international audiences and elevating Thai textiles and handicrafts to global recognition.

Today, this royal vision continues to be preserved and developed by Princess Sirivannavari Nariratana, who plays a key role in conserving and advancing Thai textiles to the international fashion and contemporary design stage. She serves as patron of the 'Royal Thai Dress on the World Stage' exhibition, presented from May 13 to November 1, 2025, at the Musée des Arts Décoratifs in Paris through collaboration with the Support Institute for Thai Craft (SACIT), the Queen Sirikit Museum of Textiles, the Royal Thai Embassy in Paris, and the Musée des Arts Décoratifs.

The exhibition celebrates the 340th anniversary of diplomatic relations and the 170th anniversary of formal diplomatic ties between Thailand and France (1856–2026). It displays over 200 pieces including royal gowns, skirts, and accessories designed by French designer Pierre Balmain in collaboration with the prestigious Lesage embroidery atelier, alongside Thai designers. The exhibition focuses on the development of royal court dress and its representation on the world stage, featuring ensembles worn by Queen Sirikit, Queen Suthida, and Princess Sirivannavari, along with eight variations of the Royal Thai Dress paired with valuable Thai handicrafts. These showcase the refinement of Thai wisdom and cultural heritage sustained over centuries, and serve as momentum for proposing the 'Royal Thai Dress' as an intangible cultural heritage representative of humanity to UNESCO in 2025.
