Thailand Intensifies Competition Enforcement in Specific Sectors

Subscribe to Updates

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 orders and impose penalties.

Business operators in these sectors should anticipate that the subcommittees’ coordination mandates will translate into more frequent information requests for market studies and sector inquiries, industry consultations, stakeholder collaborations, and joint enforcement actions with other regulators. The subcommittees’ explicit charge to prevent conduct that may affect competition signals a proactive posture rather than reactive, complaint-based enforcement. All related parties in the modern trade sector (including department stores, hypermarkets, supermarkets, convenient stores, and specialty stores) and in the digital platform sector (including e-marketplaces, online sellers, carriers, advertisers, and payment service providers operating on or alongside platforms) will also fall within the subcommittee’s oversight remit.

Recommended Next Steps for Business Operators

Business operators in the digital platform and modern trade industries should consider conducting internal compliance assessments and updating policies before the subcommittee initiates enforcement proceedings. Given the TCCT’s stated commitment to keeping pace with rapidly changing business dynamics and fostering a free and fair competitive environment, early compliance steps will be important.

In particular, digital platform operators and participants should review the following against the restrictions detailed in the March guidelines:

  • Commercial terms and contractual arrangements
  • Algorithmic pricing and ranking mechanisms
  • Data-handling practices

More broadly, all businesses operating in the Thai market should take note of the TCCT’s move toward more sector-specific and proactive enforcement, and maintain operational preparedness to ensure that commercial practices are aligned with the latest guidance.

Vietnam’s AI regulatory framework has reached an important milestone. While the Law on Artificial Intelligence No. 134/2025/QH15 (AI Law) established the foundation for AI governance, many practical compliance requirements were left to implementing regulations. On April 30, 2026, the government issued Decree No. 142/2026/ND-CP (Decree 142), which took effect on May 1, 2026, and provides the first detailed guidance on the implementation of the AI Law. Although an official list of high-risk AI systems is still pending from the prime minister, Decree 142 provides valuable insight into how Vietnam’s risk-based AI regulatory framework will operate in practice. Risk Classification Framework The AI Law adopts a risk-based approach under which AI systems are classified as high-risk, medium-risk, or low-risk. Decree 142 builds on this framework by providing detailed guidance on how these classifications are determined. High-risk AI systems are determined based on factors such as (i) their potential impact on life, health, property, human rights, public interests, or national security; (ii) the sector in which they are deployed; and (iii) the scale of affected users or integration with critical infrastructure. The latest draft list of high-risk AI systems appears to follow these same principles. Medium-risk AI systems generally include systems that may mislead, influence, or manipulate users, particularly where users may not realize they are interacting with AI or AI-generated content. The focus is therefore on transparency and authenticity risks rather than broader societal or safety concerns. Low-risk AI systems are those that do not meet the criteria for either high-risk or medium-risk classification. Importantly, Decree 142 seeks to avoid over-classification. Certain systems may fall outside the high-risk or medium-risk regimes, including internal-use systems, office-support tools, technical editing applications, certain back-end processing systems, and AI systems used in artistic, gaming, cinematic, or other creative contexts. Providers must also review and

On May 11, 2026, Thailand’s Ministry of Social Development and Human Security released a draft Child Protection Act (“CPA”) for public review. The draft CPA would completely repeal and replace the current Child Protection Act B.E. 2546 (2003). This represents the most comprehensive overhaul of Thailand’s child protection framework in over two decades, reflecting the government’s stated objective of modernizing the law to address evolving social challenges—including those arising from digital technology—and to promote greater coordination among government agencies, local authorities, and civil society. The public review period closes on June 9, 2026. Key changes introduced by the draft CPA that could have significant implications for businesses, particularly online platform providers, media companies, and entities operating child-related services in Thailand, are set out below. Expanded Definition of “Child” Under the current CPA, a “child” is defined as a person under the age of 18, excluding those who have attained legal majority through marriage. The draft CPA removes the marriage exception entirely, broadening the scope of the law’s protections to include all individuals under 18 without exception. Replacement of “Abuse” with Broader Concept of “Violence” The current CPA uses the term “abuse/cruelty,” which covers acts causing harm to a child’s liberty, body, or mind; sexual offenses against children; and using children in harmful or immoral activities. The draft CPA replaces this with the broader concept of “violence,” which encompasses any act or omission causing harm to a child’s body, mind, or development; abandonment or neglect; improper exploitation; and sexual abuse. Notably, the new definition adds developmental harm as a recognized category of injury and captures all forms of misconduct regardless of the child’s consent. New Standalone Definition of Sexual Abuse, Including Online Conduct One of the most significant additions in the draft CPA is the introduction of a standalone definition

After several years of policy discussion and continued efforts led by the Ministry of Commerce (MOC) to relax the list of reserved businesses under the Foreign Business Act B.E. 2542 (1999) (FBA), the reform process has now reached a significant milestone. On May 12, 2026, the Thai cabinet approved in principle two draft subordinate legislative instruments aimed at delisting certain reserved business activities under the FBA and reducing licensing requirements for foreign business operators. These developments signal a renewed and concrete effort by the government to modernize Thailand’s business regulatory framework in order to attract foreign investment and boost Thailand’s competitiveness in the global market. Nine Businesses Set for FBA Delisting Below is a list of the nine businesses that are being targeted for delisting from the FBA’s restrictions. A draft ministerial regulation would delist the first eight reserved businesses, while a royal decree has been drafted to delist the ninth business: Telecommunications services (Type 1 license only, covering operators without their own telecommunications infrastructure), under the supervision of the Office of the National Broadcasting and Telecommunications Commission. Treasury center services subject to the Foreign Exchange Control Act B.E. 2485 and under the supervision of the Bank of Thailand. Securities-collateralized lending, pursuant to the laws governing securities and exchange and derivatives regulated by the Securities and Exchange Commission. Agency, dealer, advisory, or fund management services relating to derivatives where the underlying assets fall outside the scope of the Derivatives Act B.E. 2546 (2003) Intra-group shared services, including administrative, human resources, and IT functions Intra-group domestic debt guarantee services Leasing of partial space for installation of financial service machines and automatic vending machines for employee use Petroleum drilling services Trading of agricultural product derivatives through a futures exchange, with physical delivery or receipt of agricultural products at a futures exchange–designated

Thailand published new rules on May 1, 2026, establishing clear procedures for how the Anti-Money Laundering Office (AMLO) handles digital assets seized during criminal and money laundering investigations. Taking effect the following day, the Regulation of the Anti-Money Laundering Board on the Custody and Management of Seized or Frozen Assets (No. 3) B.E. 2569 applies to digital asset businesses, cryptocurrency holders, and anyone subject to asset seizure under Thailand’s anti-money laundering laws. For the first time, authorities now have a detailed roadmap for transferring seized digital property from private or foreign control into secure state custody. Digital asset businesses holding customer assets under investigation must be prepared to comply with these rules compelling repatriation of such assets in enforcement actions. Expanded Definition of Digital Assets The regulation defines digital assets to include not only those covered by Thailand’s existing digital asset business law but also any other property that can be stored using the same methods as digital assets. This broad formulation means the custody rules will apply to emerging blockchain-based assets and tokenized property that may not yet fall within the statutory definition of a digital asset business, giving authorities flexibility as the technology evolves. Mandatory Transfer to Domestic Custody When digital assets are held with service providers outside Thailand, AMLO will first attempt to transfer them to an account the office maintains with a licensed domestic digital asset business operator. If the domestic operator does not support that particular asset, the office will instead move the assets to its own cold wallet (offline, internet-isolated storage system). If neither option is feasible, the seizing official will report the situation to the Anti-Money Laundering Committee for alternative instructions. A similar hierarchy governs assets held in an accused party’s private wallet or by any third party that is not a
