Ensuring Compliance with the Thai Computer-Related Crimes Act

The Link: Magazine of the British Chamber of Commerce Thailand

The Computer-Related Crimes Act (CCA) of Thailand came into force in July 2007. It was followed a month later with the publication of a Notification of the Ministry of Information and Communications Technology providing more detail relative to the scope and application of the law.

The law has attracted a certain amount of controversy particularly with regard to freedom of speech issues. That is not the focus of this article. The purpose here is to introduce the basic content of the law and consider what businesses and their staff need to do to comply with its requirements—and, of course, to avoid committing any offenses.

First, a word about context. It is now obvious that the internet is transforming society and the business world to a far greater extent than was imaginable a mere 15 years ago. Gutenberg’s printing press pales in comparison in terms of impact. From a lawyer’s point of view this dramatic online evolution (which is ongoing) creates, at a very high level, two primary areas of concern:

  • The internet as a new “venue” for committing unlawful acts
  • The internet as means to expand the reach of acts which are already classed as unlawful

Between these two poles, a vast number of issues stand to be regulated, including such issues as  contract, service responsibilities, security, consumer protection and fraud and, of course, jurisdiction. The list is extensive.

In Europe, there is a growing corpus of law aimed at making the internet safe for social interaction and commerce. The CCA in Thailand seems perhaps more stark in terms of its remit because it forms part, for the present, of a smaller body of computer-related law. Its genesis and objectives are however both recognisable and logical.

Scope

The key parts of the CCA for the purposes of this article can be broken down as follows:

  • Definitions: important, particularly in relation to who may be considered a “service provider”
  • Cybercrimes: they track for the most part the crimes enumerated in Title 1—Offences against the confidentiality, integrity and availability of computer data and systems of the 2001 Convention on Cybercrime
  • Content crimes: these relate to unlawful activities already dealt with under Thai law as they may be conducted online. This includes defamation, offences against the honour, dignity and reputation of the Royal Family and its institutions (lèse-majesté), and the dissemination of pornography or indecent information
  • Enforcement: primary responsibility lies with the Ministry of Information and Communications Technology
  • Service provider responsibilities: maintaining computer traffic data

Foreign entities conducting business in Thailand through local subsidiaries are of course subject to the provisions of the law. And importantly, a content crime does not have to be committed in Thailand to constitute an offence under the CCA. In 2011 a Thai-born U.S. citizen published online, from the U.S., a translation of Thai text that was judged offensive to the Royal Family. On his next visit to Thailand, the U.S. citizen was arrested, charged, and convicted under the CCA. (He subsequently received a Royal pardon.)

Impact of the Law

So what should foreign businesses worry about with regard to the law? Essentially, three things:

  • Doing something that may be held to constitute a crime under the CCA.
  • Being held liable as a service provider for a crime committed by an employee—or a guest in a hotel or a customer (for example, using the Wi-Fi connection in a coffee shop). CCA s.15 provides that a service provider who intentionally supports or consents to a content offence under s.14 shall be liable to the same penalty as the primary offender.
  • Failing to comply with traffic data retention requirements: a hefty fine of up to THB 500,000 can be imposed for each instance of non-compliance.

In response, prudent managers should consider the following:

  • Read the CCA—it’s widely available in translation online. Consider the content offences in particular. Act accordingly and sensitively, particularly in relation to online expression of matters touching on the dignity of the Royal Family, public morality or local politics.  Avoid defamatory statements regardless of truthfulness/veracity.  
  • Understand that the definition of service provider includes any entity which provides internet access, a local area network or server facilities. Ensure the necessary workplace, estate or occupancy policies are in place. Be alert as managers: individuals from directors to webmasters could be personally liable under the CCA if they have actual knowledge of any offense committed through the system they manage but do nothing about it.
  • Review the computer traffic data retention requirements thoroughly with the CIO or an appropriate external advisor. They are extensive yet non-exhaustive as set out in the regulations.
  • If in doubt, have no doubt: seek the advice of expert Thai counsel. This is a serious matter.

Service Provider Requirements

The basic structure of the service provider traffic data retention requirements is as follows:

  • CCA s.3 defines the service provider to include any entity which provides internet access, services for communicating between computers or computer data storage whether in its own name or via a third party.
  • CCA s.26 stipulates that a service provider shall retain computer traffic data for not less than 90 days (or up to 1 year if so ordered by a competent official) relating to identified, individual users from the start to the end of the use of the service.
  • The regulations provide further details about what data to store and how to store it.

The regulations are in three parts: the body of the regulatory text and two annexes. First, through Annex A they identify different categories of service providers, offering examples within each category. Then, in Annex B, the regulations set out the particular data that must be retained by the different categories of service providers. The lists of data are extensive but, reportedly, not exhaustive.

Finally, as general provisions, the regulations stipulate arrangements for maintaining the integrity of the data, storing it securely and in a way that makes it readily deliverable to competent officers who require it. They also require the setting of equipment to a single international reference time.

Conclusion

Surprisingly, given the importance of the law, information regarding its application in practice remains somewhat limited. This may be partly due to the fact that, in addition to the Ministry of Information and Communications Technology, a number of different enforcement agencies have been involved in enforcement of the law, including the Technology Crime Suppression Division of the police and the Department of Special Investigation. What is known is that the number of prosecutions for both cybercrime and content offences is growing—confirming both our increasing reliance on the internet and our growing need to know about its regulation as a matter of basic prudent business practice.

On March 24, 2026, the Trade Competition Commission of Thailand (TCCT) published its long-anticipated Guidelines on Multi-Sided Platforms and E-Commerce Businesses in the Government Gazette, following the conclusion of a public hearing conducted last year. The guidelines entered into force on March 25, 2026, and significantly expand the application of Thai competition law to digital platform ecosystems. These rules introduce targeted restrictions on platform conduct, such as price-ranking algorithms and tying and bunding, that leverages network effects, and will have far-reaching implications across Thailand’s digital economy—affecting not only platform operators but also platform participants, including sellers, logistics providers, advertisers, and payment service providers operating on or alongside such platforms. The guidelines clarify how existing prohibitions under the Trade Competition Act B.E. 2560 (2017) (TCA)—including abuse of market dominance, cartel conduct, and unfair trade practices—apply in the context of platform-based business models. While many provisions reflect earlier draft guidelines, the final version delivers more precise definitions and clearer enforcement parameters, increasing regulatory certainty while also raising compliance expectations. Applicability The guidelines introduce core definitions that determine their coverage: Multi-sided platform: A platform that acts as an intermediary connecting two or more groups of users, enabling them to have direct interaction in order to exchange or rely on services from one another. Examples include digital platforms for trading goods or services (e-commerce), as defined below. Digital platform for trading goods or services (e-commerce): A platform that acts as an intermediary connecting the distribution, purchase, sale, or exchange of goods or services. This includes operations carried out to facilitate transactions or interactions between business operators through an electronic transaction system, regardless of whether a service fee is charged. Operator of a digital platform business for trading goods or services: A provider of digital platform services for trading goods or services, as described

Thailand’s National Broadcasting and Telecommunications Commission (NBTC) has publicly indicated that it is preparing a new regulatory framework for data center operators that may introduce foreign-ownership restrictions. In particular, the NBTC is considering reclassifying data center operations from a type 1 telecommunications business license to a type 3 license. If implemented, this change would subject data center operators to a significantly more stringent regulatory regime, especially in relation to foreign ownership and control. The NBTC has indicated that it intends to propose a draft framework to the NBTC board. This would be followed by a public hearing process, with a view to implementing the new rules within 2026. Under the Telecommunications Business Act B.E. 2544 (2001), as amended, telecommunications businesses operating under type 3 licenses are subject to foreign ownership restrictions, including a requirement that less than 50% of the total issued shares be held by foreign shareholders. In addition, type 3 licensees are subject to foreign dominance restrictions, which prohibit arrangements that allow foreigners to dominate the business. These foreign dominance restrictions are broad in scope and may capture various forms of direct and indirect control or influence. This includes circumstances in which a foreign national is able to influence or control the formulation of policy, management, or business operations, or the appointment of directors or senior executives. At this stage, the exact scope of the proposed rules remains unclear. Businesses with existing or planned data center operations in Thailand should therefore monitor upcoming NBTC developments in this regard and prepare for the expected public hearing process.

Vietnam’s emerging governance framework for artificial intelligence (AI) is developing through a multi-layered structure comprising three components: Policy instruments setting national priorities for AI development; Regulatory framework governing development, provision, deployment and use of AI; and Technical standards and voluntary guidelines. Policy level. At policy level, the foundation for a strategic framework for AI development and governance was laid in 2021 by the National Strategy for Research, Development and Application of AI until 2030, aimed at strengthening the national AI ecosystem and positioning Vietnam as a regional AI innovation hub. Subsequently, resolution No.57-NQ/TW (2024) identified AI as a key driver of science, technology, innovation and national digital transformation. AI was also designated as a strategic technology under decision No.1131/QD-TTg (2025) listing priority technologies across sectors. Regulatory framework. At the legislative level, the new Law on Artificial Intelligence took effect on 1 March 2026, establishing the core regulatory framework governing development, provision, deployment and use of AI systems. Controlled testing for emerging AI technologies is implemented under the Law on Science, Technology and Innovation. The AI Law is expected to be further operationalised through implementing instruments, most notably a draft decree guiding the AI Law, and draft decision of the prime minister identifying high-risk AI systems (both published in February 2026). A decision establishing priority datasets for AI development is also anticipated. Compliance obligations may also arise under sectoral regulatory regimes, including data protection, cybersecurity, banking, consumer protection, e-commerce and intellectual property, particularly where AI systems are used in automated decision-making or data-driven services. Technical standards and non-binding guidelines. Vietnam’s AI governance framework is also supported by technical standards and voluntary guidelines. A key instrument is decision No.1290/QD-BKHCN (2024), providing guidelines for responsible research and development of AI systems, and represents Vietnam’s first national AI ethics code.

In response to the rapid advancement of artificial intelligence (AI) and evolving global digital trends, Thailand has undertaken significant efforts to establish a comprehensive national policy framework aimed at fostering an AI ecosystem. This framework seeks to promote the responsible development and deployment of AI technology to enhance Thailand’s economic competitiveness and improve quality of life, with targeted implementation by 2027. In furtherance of this national AI policy, regulatory authorities have initiated efforts to develop and refine the applicable legal framework, including the drafting of Thailand’s first unified AI legislation. Pending the composing and enactment of such comprehensive legislation, sector-specific regulators have proactively issued guidelines applicable to regulated entities within their respective jurisdictions, including financial institutions, banks, insurance companies, securities and derivatives business operators, and digital asset service providers. Concurrently, cross-sectoral regulatory bodies, notably the Personal Data Protection Committee (PDPC) and the National Cyber Security Agency (NCSA), have promulgated guidelines applicable to all business operators within their regulatory purview. While unified AI legislation has not been enacted, the design, development and use of AI in Thailand in various industries is still subject to existing sector-specific legislation. National AI policy The Thai cabinet approved the Thailand National AI Strategy and Action Plan (2022-2027) in July 2022, aiming to establish an AI development and application ecosystem by 2027. The strategy is built around five pillars: Preparing social, ethical, legal and regulatory readiness for AI; Developing national infrastructure; Increasing human capability and AI education; Driving AI technology and innovation; and Promoting AI adoption in public and private sectors. The above-mentioned national AI committee, under the National Digital Economy and Society Committee (NDESC), was established in August 2022, chaired by the prime minister. Comprehensive legislation Following the national AI strategy, the government has been developing comprehensive AI legislation to govern and promote AI
