This edited volume of essays examines a wide range of issues related to the regionalisation of competition policy in South East Asia, where the ten member states of ASEAN have launched the ASEAN Economic Community (AEC). Written by a diverse group of academics, practitioners and policy-makers, this book explore issues such as the role of competition policy in facilitating the market-integration ambitions of the ASEAN member states, the challenges arising from divergences in the national competition law regimes of the ASEAN member states, and the absence of a supranational legal framework and the future of competition policy in light of the AEC Blueprint 2025. Given the nexus between regional competition policy and regional market integration, this book will be of particular interest to lawyers, economists and policymakers working in the fields of competition law and regional trade law.
