In upholding a consumer's right to information, regulations prohibiting misleading or deceptive conduct perform a critical role in supporting consumer welfare and encouraging equity in business and commerce. While Vietnam enacted a Law on Consumer Protection in 2010, its provisions in this area are limited in ambit and application. In order to improve the effectiveness of a consumer's right to information in Vietnam, it is useful to examine the Australia Consumer Law which has a sophisticated regulatory framework in this area. By comparing the laws prohibiting misleading or deceptive conduct in the Vietnamese Law on Consumer Protection and the Australia Consumer Law, this article identifies certain similarities and differences between the two legal systems, thereby clarifying shortcomings that can lead to inadequacies and inefficiencies of this area of the law and providing a platform for law reform in Vietnam.
