As of the end of June 2025, construction of the Udon Thani International Horticultural Expo 2026 has reached 8.87 per cent, slightly ahead of the scheduled target of 8.70 per cent. Following the official handover of the site, implementation is now actively underway across all key zones, with recent site inspections confirming that progress is proceeding according to plan.
Significant advances have been made on major structural buildings, core infrastructure systems and landscape development, including the preparation of the nursery area and reinforcement of key riverbank sections. The project remains aligned with the overall timeline and master plan.
High-Level Monitoring and Sustainability Focus
Senior project officials and members of the national legislative committee conducted high-level monitoring visits in June 2025. These inspections reaffirmed the importance of maintaining momentum and ensuring timely execution. Strong emphasis continues to be placed on integrating environmental responsibility and long-term sustainability throughout planning and implementation.
On 12 June 2025, the Director-General and Deputy Director-General of the Department of Agriculture visited the Expo site at Nong Dae Wetland in Udon Thani. They met with project teams and local coordinators to review progress on infrastructure and landscape development, underlining the importance of keeping the project on schedule while aligning with international standards and AIPH’s sustainability framework.
International and Domestic Participation
Alongside construction, international marketing and promotional campaigns are expanding to attract global attention and encourage participation. To date, six conceptual garden designs from international participants have been approved, with several other countries preparing their submissions. On the domestic side, twelve Thai organisations have confirmed their participation through corporate gardens.
Thailand continues to welcome further expressions of interest from international participants and domestic institutions to design and construct exhibition gardens that showcase creativity, cultural identity and a shared vision for sustainability.
Regional Promotion and Community Engagement
At the regional level, Udon Thani province has launched proactive campaigns to raise awareness and strengthen community engagement. A highlight was the “Sabaidee Horticultural Caravan”, held on 5–6 July 2025 in cooperation with the Tourism Authority of Thailand and related agencies. The initiative promoted the upcoming Expo while boosting tourism and economic activity across five northeastern provinces: Udon Thani, Nong Khai, Nong Bua Lamphu, Loei and Bueng Kan.
On the Road to Udon Thani Expo 2026
The Udon Thani International Horticultural Expo 2026 is scheduled to take place from 1 November 2026 to 14 March 2027 at the Nong Dae Wetland in Udon Thani Province. Thailand remains fully committed to delivering a successful and impactful global horticultural showcase for all participants and visitors. The organisers will present a full progress report during the International Horticultural Expo Conference at the 77th AIPH Annual Congress in Ghent, Belgium, in September 2025.
