Thailand has introduced important reforms to strengthen its regulatory policy framework, but certain challenges remain. This report assesses the country's regulatory management capacity by taking stock of regulatory policies, institutions and tools; ex ante and ex post evaluation of regulations; stakeholder engagement practices; and regulatory enforcement and inspections. The review describes trends and recent developments, identifies gaps in relation to good practices, and offers policy recommendations based on best international practices to strengthen the government's capacity to manage regulatory policy. Improving the entire regulatory policy cycle will ensure that regulations are built on a foundation of solid evidence and public participation and are designed to improve the security, health and well-being of citizens at a reasonable cost. The recommendations are based on an analysis of the strengths and challenges, as well as on extensive engagement with stakeholders, within and external to the Thai administration. They also draw on lessons learnt from the implementation of regulatory impact assessment (RIA) in a range of countries, a benchmarking of RIA-related best practices, and guidance material from relevant jurisdictions.
