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.

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
