Vietnam Issues New Cybersecurity Law

Subscribe to Updates

On December 10, 2025, the National Assembly of Vietnam passed a new Cybersecurity Law, which will take effect on July 1, 2026. The new Cybersecurity Law was developed based on the consolidation of the 2018 Cybersecurity Law and the 2015 Law on Network Information Security.

While the final approved version of the new Cybersecurity Law has not yet been published, according to official reports, the following notable requirements are confirmed to be included:

  • The new Cybersecurity Law dedicates a specific article to prohibited acts related to cybersecurity, under which it strictly prohibits posting or disseminating information online that propagandizes against the Socialist Republic of Vietnam. The law also prohibits, among other things, (i) the appropriation, trading, seizure, or intentional disclosure of information classified as state secrets, work secrets, business secrets, personal secrets, family secrets, and private life; (ii) intentionally eavesdropping, recording, or filming online conversations without authorization; and (iii) the use of artificial intelligence (AI) or new technologies to conduct prohibited acts.
  • The Ministry of Public Security (MPS) has the authority to require enterprises providing telecommunications, internet, and online services, as well as system administrators, to remove information violating cybersecurity laws from systems under their management. The MPS is also assigned responsibility for ensuring information security in cyberspace and data security, establishing mechanisms for IP address identity management, verifying digital account registration information, and issuing warnings and sharing information on cybersecurity threats.
  • Information systems are classified into five levels (similar to the 2015 Law on Network Information Security) based on the degree of harm to national security and social order if an incident occurs.
  • The MPS is the lead agency assisting the government in state management of cybersecurity. The Ministry of National Defense is responsible for managing military information systems, and the Government Cipher Committee manages cryptographic and cipher information systems.

Interestingly, while the last publicly circulated draft version of the new Cybersecurity Law submitted to the National Assembly for approval had reinstated controversial data localization requirements, the official reports have not mentioned this aspect. It remains to be seen whether the data localization requirements have survived and are included in the official version of the new Cybersecurity Law.

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
