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.

Thailand’s National Broadcasting and Telecommunications Commission (NBTC) has published guidelines establishing a risk-based framework for the responsible use of artificial intelligence by telecom licensees. Released on July 2, 2026, the Guidelines on the Use of Artificial Intelligence for Telecommunications Services address governance structures, ethical principles, lifecycle management, and consumer protection obligations. Scope and Legal Context The nonbinding guidelines apply to holders of telecom business licenses under Thailand’s telecom licensing laws, but only with respect to the use of AI in providing licensed telecom services. Entities without such licenses are not directly subject to the guidelines, though they may be affected as third-party AI solution providers to licensees. The guidelines supplement and should be read alongside existing laws, including the Cybersecurity Act, the Personal Data Protection Act (PDPA), the Computer Crime Act, and the NBTC Notification regarding Measures to Protect Telecommunications Service Users’ Rights Regarding Personal Data, Privacy Rights, and Freedom of Telecommunications, as well as forthcoming AI governance legislation being drafted by the ETDA. AI Governance Structure Licensees are expected to establish committees, working groups, or designated officers at both policy and operational levels to set strategic direction for AI use, formulate governance policies and tools, and oversee risk management. Roles, responsibilities, and accountability should be clearly defined for all personnel across every stage of the AI lifecycle—including for third-party AI solution providers and outsourced service providers, whose obligations should be explicitly documented in service agreements. Core Principles The guidelines identify six core principles that licensees should adhere to when deploying AI: Compliance with laws, ethics, and international standards: AI should respect privacy, dignity, and human rights, and content filtering for inputs and outputs should be considered. For example, the AI should not be designed and developed to be used in generating false information, supporting illegal activities, or causing

Vietnam has taken a significant step in regulating its e-commerce sector with the issuance of a new decree guiding the country’s recently enacted Law on E-Commerce. Decree No. 248/2026/ND-CP, issued on June 30, 2026, and taking effect the following day, addresses mandatory platform policies, registration requirements for offshore platforms, additional obligations on platform operators, and market access conditions for foreign investors. Mandatory Policy Contents The decree sets out detailed guidance on the required contents of various platform policies, covering pricing, payment, display priority, livestream sales, delivery, returns, method of service provision, and service termination and refunds. Clarification of Obligations for Platform Operators The decree provides clarification of the obligations applicable to platform operators. Notably, intermediary e-commerce platform operators with online ordering functions must: Collect specific information to implement electronic identity verification of sellers; Cooperate with regulators by reporting online through the state e-commerce management system and by blocking, suspending, or removing content upon request of a competent authority; Maintain a mechanism to store contract data, including price, product or service information, and parties’ information, for at least three years from the date of contract conclusion; and If qualifying as a “large digital platform” under consumer protection law, maintain an online system for receiving and handling complaints and requests, and comply with enhanced content-removal requirements. Registration Requirements for Offshore Platforms Offshore e-commerce platforms, whether direct-sales, intermediary, social-network-based, or integrated, that conduct e-commerce activity in Vietnam must register with the Ministry of Industry and Trade if the platform: Allows Vietnamese-language selection; Uses a “.vn” domain; or Reaches 100,000 or more transactions with Vietnam-based buyers within a calendar year. Notably, the registration requirement now captures not only traditional intermediary platforms, but also direct-sales platforms.

On July 7, 2026, the Trade Competition Commission of Thailand (TCCT) issued a press release announcing the establishment of two new subcommittees designed to intensify oversight of digital platforms and modern trade businesses. The formation of the digital platform subcommittee marks a significant escalation in competition enforcement following the TCCT’s Guidelines on Multi-Sided Platforms and E-Commerce Businesses, which took effect on March 25, 2026. Platform operators, sellers, and related service providers should expect heightened regulatory scrutiny and potential investigations into practices already flagged under the March guidelines. Two Dedicated Enforcement Bodies The first new body is the digital platform subcommittee—formally the Subcommittee on Supervision, Monitoring, and Prevention of Trade Conduct in Digital Platform Business. It is tasked with driving intensive oversight of digital platform businesses. It will coordinate with government agencies, the private sector, business operators, and other relevant stakeholders to supervise and prevent trade conduct that may affect competition, and to promote free and fair competition in the digital platform sector. The subcommittee will be composed of TCCT members and representatives from the Department of Internal Trade. The second body—the Subcommittee on Determining Guidelines and Action Plans Concerning Competition Conditions in Modern Wholesale and Retail Business—will study, analyze, and monitor market structure in modern wholesale and retail businesses, compile databases to analyze retail business concentration, assess impacts on small-scale operators, and propose supervisory measures for the retail sector. TCCT members will serve on the subcommittee alongside experts from government and private organizations, including the Office of Industrial Economics, the Office of Small and Medium Enterprises Promotion, the Thai SME Federation, and the Thai SME Council. Operational Impact for Industry Participants These subcommittees provide the TCCT with a focused mechanism to investigate various trade practices deemed unfair, and the TCCT has authority under the Trade Competition Act to issue cease-and-desist

Vietnam has introduced an official list of high-risk AI systems, triggering more stringent compliance obligations for developers, suppliers, and deployers operating in the country. On June 30, 2026, the prime minister issued Decision No. 33/2026/QD-TTg (Decision 33), which establishes the List of High-Risk AI Systems under the Law on Artificial Intelligence (AI Law) and Decree No. 142/2026/ND-CP (Decree 142). Decision 33 takes effect on August 15, 2026. Decision 33 is significant because only AI systems included on the list will be subject to the heightened compliance obligations applicable to high-risk AI systems under the AI Law and Decree 142. These include, among others, local presence requirements for foreign providers, mandatory conformity assessment before deployment, comprehensive risk management and data quality documentation, and strict liability for damages even when the provider is fully compliant. Decision 33 also specifies the applicable conformity assessment pathway for each listed system, indicating whether the system must undergo mandatory third-party conformity certification before being placed into use, or whether the provider may self-assess conformity or voluntarily engage a registered or recognized conformity assessment body. Which AI Systems Are Covered? Decision 33 identifies high-risk AI systems across six sectors—the key attributes of which are summarized below. Education: AI systems used for automated assessment, learner ranking, behavioral monitoring, or generating educational content from uncontrolled data sources. Ethnic affairs and religion: AI systems used to automatically score, classify, or rank applications for government ethnic policies; approve or reject regulatory applications; suspend benefits on suspicion of fraud; allocate budgets; or infer and classify individuals by ethnicity or religion for administrative purposes. Healthcare: AI-assisted surgical systems and autonomous AI-powered surgical robots. Banking: AI systems that autonomously conduct electronic banking transactions or make credit approval decisions. Judicial proceedings: Certain large-scale biometric identification systems used in public-interest civil proceedings. Transport: Thirty-one categories
