Cambodia’s new Sub-Decree on the Management of Commercial Advertising of Products and Services, issued November 4, 2022, is a notable step in ensuring that advertisers comply with advertising regulations, advertise ethically and legally, and avoid deceiving or misleading consumers. The sub-decree regulates both traditional advertising (e.g., print, broadcast, display, etc.) and digital forms (e.g., social media, online, mobile, etc.), and also includes provisions that address advertising alongside rewards—a popular method of advertising in Cambodia. The Ministry of Commerce is the authority tasked with issuing certificates of advertising compliance (more below) and is responsible for monitoring and assessing the compliance of advertisements with this sub-decree and related regulations. The ministry also enforces against unfair advertising through its Consumer Protection, Competition and Fraud Repression Directorate-General (CCF). Key Issues The sub-decree addresses a range of key issues relevant to companies advertising products and services in Cambodia. Licensing The sub-decree does not appear to set new licensing or permit requirements, but it requires advertisements for products and services to comply with the sub-decree, any existing regulations (unless they contradict the sub-decree), and future regulations. If regulations require a license for advertising, this should be obtained from the relevant authorities. One example is advertising of pharmaceuticals, which requires a license from the Ministry of Health under existing regulations. Types of Advertisement Under the sub-decree, advertising is divided into two types: advertisements with rewards and advertisement without rewards. Rewards may include souvenirs, lucky draws, and other rewards attached to the purchase of products and services. Forms of Advertisement Forms and means of advertising specified in the sub-regulation include the following: Advertising via audiovisual media such as TV, electronic broadcasting media (including both satellite and cable TV), and so on; Electronic advertising, such as websites, e-mail, electronic messages (in written, voice, or image form), ringtones, social
