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
