Thailand’s Advertising Guidelines Targeting AI-Generated Content

Subscribe to Updates

Thailand’s AI legislative framework took another step forward when the Office of the Consumer Protection Board (OCPB) issued a notification establishing guidelines for AI-generated advertising that may cause material misunderstanding about products or services. The notification, which is already in effect, was issued under the Consumer Protection Act B.E. 2522 (1979) and its amendments, which prohibit advertising that is unfair to consumers or may cause harm to society, including false or exaggerated statements and statements that may cause material misunderstanding about products or services.

The notification addresses emerging advertising practices, including the use of images edited using software or AI to attract consumer interest or build credibility. The OCPB noted that such advertising may result in consumers misunderstanding the essential characteristics, condition, or usage of products, which violates consumer rights and causes damage.

Key Requirements on AI-Generated or Digitally Manipulated Advertising Content

For advertisements using still images or videos created or edited with software programs or AI tools that may cause the depicted product or service to differ from the actual product sold or service provided—which may cause misunderstanding regarding the condition, quality, quantity, or other essential aspects of the products or services—advertisers and business operators must comply with the following requirements:

  • Prior authorization. Obtain approval from relevant regulatory authorities where required by law.
  • Accurate representation. Ensure that the advertised size, quantity, volume, number, or composition matches the actual product or service being sold, whether in still images or videos.
  • Mandatory AI disclosure labels. Display clear disclosures when AI or software is used to create or edit images, such as:
    • “Real image or simulation edited using AI”
    • “Photo from actual location or simulation edited using AI”
    • “Photo from actual product or edited simulation”
    • “Image created by AI”
    • “Video created by AI”
  • Clarity of disclosure. Ensure disclosures are clearly visible, audible, or readable according to the type of advertising medium.

Recommendations

Business operators should assess their current advertising practices and update internal policies to ensure compliance with these new disclosure and warning requirements. Companies should ensure that marketing contracts and creative workflows incorporate the mandatory disclosures specified in the announcement. In particular, operators that develop, use, or rely on AI systems in their marketing activities should assess their current data governance practices and oversight mechanisms. Businesses should also monitor the ongoing development of Thailand’s broader AI regulatory framework to ensure timely compliance with future requirements.

Indonesia’s regulation on reporting online intellectual property (IP) infringement provides comprehensive procedural guidance for IP rights holders and their licensees in reporting online infringement complaints. Issued in December 2025 by the Ministry of Law as Regulation No. 47 of 2025 regarding Handling of Intellectual Property Infringement Reports in Electronic Systems, this regulation covers all types of IP rights. It also specifies documentation when reporting infringement, and lays out the procedures for examination, verification, and enforcement actions. Submission of Complaints Complainants may submit reports through the online system of the Directorate General of Intellectual Property (DGIP) or in person at the DGIP office. Complaints may also be filed through an authorized proxy. Under the regulation, complainants are required to provide the following information and documents: Personal details of the complainant; Brief description of the protected work or subject matter (i.e., type of IP and name or address of the infringing website, portal, account, or application, or a link to the location of the infringing content); Complete description of the alleged infringement; Certificate of registration or recordal of the relevant IP; Recordal of IP license agreement, if any; and Other supporting evidence. Verification and Examination Process Upon receiving a complaint, the responsible formality officer may request clarification or additional supporting documents. In the latter case, the complainant must then submit the necessary administrative documents within 14 days of the notification date. Once the documentation is deemed complete and sufficient, the case will be formally registered. Subsequently, the DGIP will establish a verification team to handle online IP violations, which will include the Civil Servant Investigator (PPNS), the Ministry of Communication and Digital Affairs, experts with relevant expertise in IP, and representatives from related associations such as AVISI (Indonesian Video Streaming Association). After examining the report, the team will prepare the Minutes

Thailand’s Electronic Transactions Development Agency (ETDA) released a new version of the draft Act on Artificial Intelligence on July 2, 2026, for a public hearing period expected to be approximately 30 days. The draft act adopts a risk-based regulatory approach modeled in part on international frameworks—particularly the EU’s AI Act—while incorporating provisions tailored to Thailand’s regulatory landscape and digital economy objectives. If enacted in its current form, the law would introduce extraterritorial obligations, a tiered risk classification system, strict liability for AI-related damages, and new transparency requirements for AI-generated content. Scope and Extraterritorial Application The draft act applies to AI development, deployment, or any other action affecting people in Thailand, even if the action occurs outside the country. Of note: This extraterritorial reach creates compliance obligations for global AI companies whose systems impact Thai residents or consumers, even if the provider has no physical presence in Thailand. Foreign AI providers serving Thai deployers or users must appoint a local coordinator or authorized representative. Depending on the type of AI system, the representative may need full authority to act on behalf of the provider without any limitation of liability. Certain activities are exempt from the draft act’s oversight, including AI used by natural persons solely for personal or household activities, AI for educational research conducted by higher education institutions with ethics committee approval, research and development activities conducted prior to distribution or service provision, and other AI systems prescribed by royal decree. Risk-Based Classification Framework The draft act establishes a tiered risk classification system with three main categories: Prohibited AI. The act outright prohibits AI systems employing cognitive-behavioral manipulation using subliminal techniques, AI systems causing unfair broad-scale discrimination from processing irrelevant data, and other categories of serious risk as determined by announcement of a forthcoming committee that will be responsible

Thailand’s cabinet has approved the draft Act on Liability for Defective Goods, commonly called Thailand’s “Lemon Law.” The Draft Act is currently pending consideration by Parliament. The draft law aims to strengthen buyers’ position in pursuing cases against sellers. While the Civil and Commercial Code offers provisions governing liability for defective goods, it is difficult in practice for buyers to successfully make a claim against sellers, particularly where defects are latent and not discoverable at the time of sale or delivery. By introducing product-specific rules and clearer remedies, the new law is intended to modernize Thailand’s consumer protection framework and align it more closely with international standards, and to help relieve the buyer’s burden of proof against the seller in product liability cases. If enacted, the draft act will take effect 180 days after publication in the Government Gazette, giving businesses a transition period to assess their compliance obligations. This article provides an overview of the key provisions of the draft act and highlights some practical considerations for businesses operating in Thailand. Scope and Key Definitions The draft act applies to sellers—defined as persons who sell goods in the ordinary course of business—and protects buyers, a term defined broadly to include not just the original purchaser but also transferees and successors in title. This expands the class of people who can bring claims. The law does not apply to used goods, live animals, or goods exempted by future ministerial regulation. It also leaves intact any separate warranties, promises, advertisements, or other guarantees a seller has given; those remain enforceable alongside the new statutory rights. General Liability for Defective Goods Sellers are liable for defects that exist at the time of delivery, regardless of whether the seller knew about them. Liability arises where a defect reduces: The benefit intended under
