The European Union is the home of the most experienced supranational competition law system of the world. Hence, other regional integration systems often look at the EU as a role model for designing their regional competition policies. However, this does not necessarily argue in favour of a ‘copy-and-paste’ adoption of the European framework. ASEAN has chosen to implement a regional competition policy framework as part of its project to create an ASEAN single market and an ASEAN Economic Community. However, ASEAN’s approach to competition law is limited to convergence. This Chapter discusses whether and to what extent ASEAN should now go a step further and ‘transplant’ the EU competition law framework. The answer depends on a number of considerations such as the goals of creating a supranational competition law, the degree and potential of economic integration of the national economies, the level of economic development of these economies, the development of a competition culture in these countries, the comparative advantages of centralised and decentralised enforcement and the willingness of ASEAN countries to surrender sovereignty in the field of competition law.
