Update on the Implementation of Vietnam’s New Cybersecurity Law and Status of Implementing Decrees

Vietnam’s new Cybersecurity Law was promulgated on June 12, 2018 and came into effect on January 1, 2019, with a majority of its provisions enforceable from the effective date. However, there are still certain provisions of the law which need to be further guided by implementing regulations and guidelines. There are currently draft guidelines under consideration, including:

  • A decree to implement in detail some provisions of the law, which includes guidance on the important and controversial article 26 on data localization (to guide articles 10.4, 12.5, 23.1, 24.7, 26.4 and 36.5, among others);
  • A decree to regulate in detail the procedures for application of cybersecurity protection measures (to guide article 5.2 of the law); and
  • A decision of the prime minister on promulgation of the list of national security information systems (to guide articles 10.3 and 43.3 of the law)

As of the time of writing this update, none of the three proposed regulations has been promulgated. The draft decree that most concerns industry insiders is the first, which regulates data localization. The draft is now in the Office of the Government for consideration and approval but there has been no official news as to when it will be issued. Although there was some indication earlier in 2019 that the Government was expected to pass the decree by the end of the year, an unofficial source said that it appears to have now been delayed to Q1 of next year, 2020. The latest accessible version of the draft decree is the version dated August 21, 2019.

The Ministry of Public Security’s (MPS’s) process of drafting this decree has demonstrated the ministry’s willingness to be open to industry and public consultation, because the issues surrounding the data localization requirement have generated significant concerns and numerous comments from international organizations and companies. According to reports, up to September 2019, the MPS sent 216 letters to relevant ministries and agencies, both at the central and local levels, as well as organizations and experts for comments. Based on these consultations, the MPS has made some changes. For example, it made changes to the specifications of different types of data that needs to be stored in Vietnam and added more services which will give rise to a data localization requirement. In addition, the MPS reduced the number of conditions that trigger data localization from four to just three (in particular, leaving out the ambiguous condition of letting service users continue to carry out prohibited acts). However, it is still uncertain whether the final version the government will pass will be much different from or improve this version.

It is worth re-emphasizing that the most problematic provision of the Cybersecurity Law is article 26.3, which relates to the requirements of data localization. The article states:

“Domestic and foreign enterprises providing services on telecommunication networks or the internet or value-added services in cyberspace in Vietnam with activities of collecting, exploiting, analyzing, and processing personal information data, data on the relationships of service users, or data generated by service users in Vietnam must store such data in Vietnam for the period prescribed by the government. Foreign enterprises mentioned in this clause must open branches or representative offices in Vietnam.”

The draft decree has narrowed down this broad language. Based on the draft decree, storing data and/or having branches or representative offices in Vietnam is required for foreign service providers only for the protection of national security, social order and safety, social ethics and health of the community, and when there are legal bases for a full determination on the three following factors:

  • Such enterprise provides regulated services:
  • Such enterprise carries out activities of collecting, exploiting [using], analyzing and processing the regulated types of data; and
  • Such enterprise has been warned that the services it provides are used to commit a breach of the laws of Vietnam and it does not take any measures for avoiding, dealing with, fighting against or preventing such breach, or resisted, obstructed, or ignored requests from the relevant authorities.

Regulated services include: telecom services; services of data storage and sharing in cyberspace; supply of national or international domains to service users in Vietnam; e- commerce; online payment; intermediary payment; service of transport connection via cyberspace; social networking and social media; online electronic games; and services of providing, managing or operating other information in cyberspace in the form of a message, phone call, video call, email or online chat.

Regulated types of data include:

  • Data on personal information of service users in Vietnam, including data with information in the form of symbols, writing, numbers, images, sounds or similar forms in order to accurately determine the identity of any one person;
  • Data generated by service users in Vietnam, including account names for use of services, duration of use of services, credit card information, email addresses, IP addresses for the latest login and logout, and registered telephone numbers attached to the account or data relevant to the data on personal information of service users; and
  • Data on the relationships of service users in Vietnam, including friends, and groups with which the users connect or interact.

Relevant authorities include the Department for Cybersecurity and Prevention of High-tech Crime under the Ministry of Public Security and/ or the Cyber Task Force, which comprises the Department for Cybersecurity and Prevention of High-tech Crime under the Ministry of Public Security and the Cyber Operations Command under the Ministry of National Defense.

If an enterprise were required to store data or have a branch or representative office in Vietnam, it would receive an MPS decision requiring it to store data and/or establish a branch or representative office in Vietnam. Within six months from the date of the MPS’s decision, the enterprise must complete the storing of data and/or establishing of a branch or representative office in Vietnam. Compared to the previous draft, this draft has significantly shortened this period from 12 months to six months, which is a disadvantage for enterprises. The period for storing data will start from the date on which the enterprise receives a request for storage of data until such request ends. The period for the storage of data will be at least 12 months. The period for having a branch or representative office in Vietnam will start from the date on which the enterprise receives a request until the enterprise no longer operates in Vietnam or provides regulated services in Vietnam.

How has the Cybersecurity Law affected foreign service providers since it came into effect nearly 12 months ago? Clearly, foreign service providers now face more risks if they do not take steps to restrict sensitive content or respond to takedown requests. According to reports, a senior official at the Ministry of Information and Communications recently commented that foreign companies’ compliance relating to content issues has greatly increased. For example, according to the official, cooperation with takedown requests in some areas related to content has increased from 20-30% to nearly 80-90%. In addition, the official added that it is also expected that the enforcement of the Cybersecurity Law will result in greater compliance among service providers when the authorities request them to provide service users’ identities if a violation of the law is detected.

Thailand’s Electronic Transactions Development Agency (ETDA) has released a revised draft Electronic Transactions Act (ETA) for public hearing from May 12, 2026, to June 15, 2026. This is not merely an amendment to certain provisions of the current ETA, but a comprehensive redrafting of the entire act. The revised draft ETA introduces several significant changes from the current framework, with practical implications for businesses operating in Thailand. Unified Coverage of Public and Private Sectors The current law segregates government transactions into a separate chapter with distinct rules. The draft ETA eliminates this division, defining “transaction” to encompass civil and commercial juristic acts as well as administrative procedures, administrative contracts, and other acts of government agencies. Enhanced E-Signature Definition The definition of “electronic signature” is broadened to expressly include biometric data and refocused on identifying the signatory and demonstrating intent regarding the content of the electronic data. Shift in Burden of Proof When a party challenges the reliability of electronic data created using a “trusted electronic method” or a method prescribed by the ETDA, the burden of proof and the cost of proving unreliability shifts to the challenger. Introduction of New Digital Method Concepts The draft ETA introduces several new digital method concepts that are not currently recognized under the existing ETA framework. These include: Electronic timestamping (e-timestamp) Electronic registered delivery Electronic company seals Electronic stamp duty compliance Electronic identity authentication and verification Electronic transferable records (electronic bills of lading, promissory notes, and similar negotiable instruments) Recognition of Automated Systems and Electronic Contracting The draft ETA expressly recognizes the legal validity and enforceability of contracts formed through automated systems, including contracts concluded entirely between automated systems or between an automated system and a person. A party may not deny the binding effect of such contracts solely because no human review

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
