With a population of 600 million, the combined economy of the 10 nations comprising the Association of Southeast Asian Nations (ASEAN) ranks as the ninth largest in the world. With the ASEAN Economic Community (AEC) set to be realised on December 31 2015, most ASEAN countries must comply with the AEC Blueprint, which sets out guidelines for ASEAN to achieve its goal of becoming a single market by 2015. IP rights are an important issue in the blueprint. Given the region’s tremendous growth, many rights holders are eager to access ASEAN’s surging middle class. Yet IP infringement remains rife in much of the region, and rights holders must cope with vast differences in the legal regimes from one country to another. This chapter provides a guide to anti-counterfeiting in some of the key markets in Southeast Asia: Thailand, Cambodia, Laos, Myanmar, Indonesia and Vietnam.
