Vietnam Issues New Cybersecurity Law

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 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

On May 8, 2026, the Thai government held a press conference to announce a coordinated, multiagency initiative to strengthen oversight and enforcement over products sold on online platforms. The initiative involves the Office of the Consumer Protection Board, the Thai Industrial Standards Institute, the Electronic Transactions Development Agency, the Thailand Consumers Council, the Consumer Protection Police Division, and major online platform operators. With this appointment, the government has signaled a deliberate shift from a predominantly reactive enforcement framework toward a more proactive regulatory and monitoring approach for online commerce and digital platform services. Legal and Regulatory Reform The government is accelerating a proposed Product Liability Law that would introduce new statutory frameworks for defective or substandard products, along with amendments to food safety and consumer protection legislation. The draft law has already been approved by the cabinet; the Council of State and relevant authorities will further draft the law and subsequently issue it for public hearings prior to enactment. Authorities also plan to expand enforcement measures against noncompliant businesses and distributors. In particular: The implementation of stricter “know your merchant” (KYM) identity verification requirements for online sellers. Expanded mandatory standards and regulatory oversight for high-risk products, such as power banks, electrical appliances, food products, and household goods. Increased monitoring of online product listings, and coordination with platform operators to remove unsafe, counterfeit, misleading, or otherwise noncompliant products. Additional monitoring and enforcement measures targeting online scams and illegal goods distributed through digital platforms, including e-cigarettes, which authorities identified as a growing concern due to increasing online distribution channels and potential health impact on young consumers. Strengthening Consumer Complaint Mechanisms The government announced increased cooperation with the Thailand Consumers Council and other agencies to facilitate complaint handling, market monitoring, and policy recommendations. Enhanced interagency coordination will aim to ensure that consumer

Thailand’s telecommunications regulator has introduced a range of new compliance obligations for telecom licensees aimed at preventing and suppressing technology crime. On May 15, 2026, the National Broadcasting and Telecommunications Commission (NBTC) published in the Government Gazette Notification on Measures for Prevention and Suppression of Technology Crime No. 2, which amends the original NBTC notification dated August 24, 2025. The amendment derives its authority from the Emergency Decree on Measures for Prevention and Suppression of Technology Crime B.E. 2566 (2023), as amended in 2025, and took effect on May 16, 2026. SIM Card Registration Cap for Non-Thai Nationals Persons without Thai nationality are now limited to a maximum of three SIM cards per person per service provider. Identity verification must be done primarily via passport. For those without a passport, acceptable alternatives include travel documents or certificates of identity issued by foreign governments, accompanied by additional Thai government-issued documents, as well as pink ID cards (for persons without Thai nationality) and white ID cards (for persons without registration status). Registration must be done in person at a branch or authorized dealer. Service providers must develop their identity verification systems and obtain NBTC approval before deployment. SIM Activation Deadline and SIM Box Prohibition Both Thai and non-Thai service users must activate their registered SIM within 60 days of registration. If they fail to do so, they must re-verify their identity in person before activation, confirming they are the same person who originally registered. Service providers must prohibit SIM box and gateway devices capable of supporting four or more SIMs from connecting to their mobile networks unless the device has received a license under the Radio Communications Act. Blacklist Enforcement Service providers must refuse registration of additional mobile numbers for persons listed on a technology crime-related database maintained by the Royal

Thailand has introduced new requirements for online social media platforms to verify the identity of paying advertisers before publishing their advertisements. On May 5, 2026, the Electronic Transactions Commission published the Notification on Measures for Prevention of Technology Crime for Online Social Media (No. 2) in the Government Gazette. The notification, which aims to prevent technology crimes such as fraud and scams, takes effect 180 days after publication (i.e., on November 1, 2026). Mandatory Advertiser Identity Verification Online social media service providers must verify the identity of every advertiser before publishing an advertisement. Verification remains valid for up to one year from the most recent verification date. The notification requires social media providers to use either of the following methods when verifying advertisers: Document-based verification: Examine government-issued identity documents (e.g., national ID, passport, or juristic person registration certificate), cross-check the connection between the advertiser and the identity documents (e.g., facial comparison with photo ID), and ensure that the identity documents are verifiable against reliable sources. Digital identity verification: Use an identity verification system with a level of assurance no lower than that prescribed by the Electronic Transactions Commission. Advertiser Data Collection and Retention Service providers must collect and retain certain data—including name, identification number, and contact details—from the start of the advertising service and for a minimum of 90 days after the end of the advertising service relationship. The same requirements apply where there is a third-party payer, such as an ad agency. Implications for Affected Businesses The notification raises two key areas of concern for affected businesses: Social media platforms must implement know-your-advertiser (KYA) onboarding as described above, including document upload and identity matching processes. The 180-day implementation window requires immediate technical and operational planning. The collection and retention of national ID cards, passport copies, and other personal
