On May 2, 2025, the Trade Competition Commission of Thailand (TCCT), in cooperation with the OECD, held a conference to discuss the results of the OECD Peer Review of Thailand’s competition law and policy. This review, conducted under the second phase of the OECD-Thailand Country Program, marks a significant milestone in Thailand’s ongoing institutional reform. Tilleke & Gibbins’ trade competition experts were invited to participate in both the program and the conference. The OECD Peer Review aimed to assess the current state of Thailand’s legal and regulatory environment surrounding competition law and policies, pinpoint strengths and weaknesses, and offer recommendations on potential future development. This article highlights the review’s key findings and recommendations, and their implications for businesses operating in Thailand. Institutional Framework: Room for Improvement Competition law in Thailand has undergone significant transformation, particularly since the enactment of the Trade Competition Act B.E. 2560 (2017) (TCA). This landmark legislation aimed to revolutionize the competition regime, notably by amending important legal provisions to enhance public enforcement capabilities and establishing the TCCT as an independent authority separate from government ministries, endowed with its own budget and powers to enforce competition law across key areas: anticompetitive agreements, abuse of dominant market positions, merger control, and unfair trade practices. The goal was to create a more efficient, flexible, and independent agency and to prevent political intervention. However, the OECD Peer Review points out a major impediment. The TCCT faces considerable budget and human resource constraints, which may impact its enforcement capacity. Its budget is comparatively low by international and regional standards, and only a fraction of its staff is dedicated to core competition enforcement (merger control and anticompetitive behavior). Furthermore, there is room for the TCCT to continue its improvements in expertise and efficiency—areas the TCCT has been attempting to shore up
