On 10th and 11th September 2025, CoST’s new Chair Rajiv Lall visited Thailand to celebrate their progress of successfully implementing the CoST approach over the past 10 years.

Thailand joined CoST in 2015. Since then they have published data on 7,118 public infrastructure projects on their website for the public to view, which has just over 100,000 views since it was updated last year. The Comptroller General’s Office have also reported budget savings of 8.45% due to the deterrence impact of the CoST approach.

The visit began with a visit to the Chakri Naruebodindra Medical Institute of Ramathibodi Hospital, Bangkok to see how the state of the art teaching facility was built and monitored to ensure it was built efficiently and to a high quality, including being one of the projects Thailand selected to independently review as per the CoST approach.

Next Rajiv and CoST’s Head of Advocacy and Communications, Justine Wharton, met with Mr Prayong Hirunyawanich, Executive member of Anti-Corruption Thailand (ACT) and former Chair of the CoST Thailand Multi-Stakeholder Group, CoST Board member Kittidej Chantangkul and CoST Thailand Manager, Chanon Chamnankit to discuss the role of the civil society and the Multi-Stakeholder Group in delivering the CoST approach. The day finished with a meeting with senior officials from the Royal Thai Government including Mrs Pattaraporn Vorasaph, Comptroller-General’s advisor on fiscal and financial development and Ms Nitiyaporn Imjai, MSG Secretary and Director of Public Procurement Cooperation & Transparency Division, to discuss their learning so far and future ambitions to grow the CoST approach further.

On the 11th, the visit continued with meeting members of the private sector and civil society representation on the CoST Thailand Multi-Stakeholder Group. The visit then cumulated with a meeting with the Governor of Bangkok to hear of his support for the CoST approach where Rajiv awarded certificates on behalf of CoST Thailand to 7 Bangkok Metropolitan Authority infrastructure projects that had achieved 100% data publication rates.

Thank you very much to all of the CoST Thailand team, representatives of the Royal Thai Government, ACT, Bangkok Metropolitan Administration and other private sector and civil society representatives for their time and hospitality during this visit, as well as their continued commitment to the CoST approach.
