Integrity is a cornerstone of good governance, sustainable development, and public trust. As Thailand continues its efforts to strengthen public institutions, promote transparency, and foster inclusive economic growth, reinforcing integrity across the public sector remains both a priority and a shared responsibility.
The 2018 and 2021 OECD Integrity Reviews of Thailand, the first carried out in Southeast Asia, demonstrated the Government of Thailand’s commitment to investing in public integrity and learning from the practices and expertise of OECD countries. This 2026 follow-up review provides a comprehensive assessment of the country’s integrity system; examining policies, institutions, and practices that shape ethical conduct, accountability, and the prevention of corruption. It highlights progress made in recent years, identifies persistent challenges, and offers recommendations to support on-going reforms. Particular attention is given to whole-of-government approaches, ethical leadership, enforcement mechanisms, and the role of public participation in safeguarding integrity.1
Tackling corruption in the public sector and building transparent and accountable public institutions fosters investment, encourages competition, and improves government efficiency. The policy recommendations in this Integrity Review seek not only to bolster Thailand’s integrity system, but also to promote public trust and ensure that the country can continue down a path of sustained economic growth.
The follow-up review is based on extensive analysis, stakeholder consultations, and comparative insights drawn from international good practices. It recognises the complexity of Thailand’s governance context and underscores the importance of tailoring integrity measures to national priorities, administrative capacity, and societal expectations. Furthermore, it provides the government with a roadmap of concrete actions to strengthen its institutions and resilience to corruption risks.
This follow-up review presents Thailand with an opportunity for strengthening integrity in the public sector and embark on critical and necessary reforms, demonstrating strong political will alongside government commitment. It also intends to be a practical reference for policymakers, public officials, civil society, and the private sector, contributing to informed dialogue and sustained action to advance integrity and good governance in Thailand, in line with the OECD Recommendation of the Council on Public Integrity.
