New Decree Provides Guidance for Vietnam’s Personal Data Protection Law

Subscribe to Updates

On December 31, 2025, the government of Vietnam promulgated Decree No. 356/2025/ND-CP detailing and guiding the implementation of the new Personal Data Protection Law (PDPL) that was issued in June 2025. The new decree, like the PDPL, entered into force on January 1, 2026, with the previous Decree No. 13/2023/ND-CP on personal data protection ceasing effect on the same day.

Some key points of the new decree include the following:

  • Comprehensive lists of basic and sensitive personal data are provided, which will require companies to review again their existing documents and data type classification to ensure compliance.
  • New timelines are established for responding to specific data subject requests. These timelines are more reasonable and longer than the previous 72-hour requirements.
  • Additional consent guidelines are provided, prohibiting default consent or ambiguous instructions that confuse data subjects about giving or withholding consent.
  • Mandatory content for data transfer agreements/clauses in particular cases is provided. This covers, among other things, (i) the legal basis for the transfer of personal data; (ii) responsibilities for personal data protection during the transfer and processing of personal data; (iii) responsibilities for ensuring the exercise of the rights of personal data subjects; and (iv) responsibilities for coordination and compliance of the parties in cases where violations of personal data protection regulations are detected.
  • The qualifications and responsibilities of data protection officers (DPOs) and data protection departments include, among others, having been trained and fostered in legal knowledge and professional skills regarding personal data protection. There are no specific provisions governing the qualifications or requirements for organizations that provide data protection training or education.
  • New mandatory templates and requirements are provided in relation to data processing impact assessment and data transfer impact assessment, and for cases in which companies need to re-submit assessments to the regulator.
  • Stricter requirements are applied to enterprises providing data processing services, including mandatory licensing, annual compliance and credibility assessments, and impact assessments dossiers approved by the relevant authorities.
  • Specific notification requirements are introduced for violations relating to personal location data and biometric data.
  • Personal data must be de-identified before being traded on a data trading platform.
  • Small enterprises and startups have a five-year grace period from the effective date of the PDPL to comply with regulations on preparing impact assessment dossiers and designating departments and/or personnel to protect personal data. Business households and micro-enterprises are exempted from these regulations. The grace period and exemptions, however, do not apply (i) when the scale of processing reaches 100,000 or more personal data subjects; (ii) in the provision of data processing services; or (iii) in cases where sensitive personal data is directly processed.
  • Specific provisions are set out concerning data protection in relation to banking, credit information activities, AI, metaverse technologies, big data, blockchain, cloud computing, and related fields.

Outlook

With the PDPL and its guiding decree already in effect, it is imperative that companies proactively assess and implement the new requirements to ensure ongoing compliance. Organizations are also encouraged to continuously monitor regulatory updates and additional guidance to remain informed and adequately prepared for any changes.

Thailand’s Personal Data Protection Act B.E. 2562 (2019) (PDPA) could soon see some important changes, as a draft bill to amend the PDPA has been introduced in the House of Representatives. The draft amendment is currently in the public consultation phase, with comments accepted from July 16 to August 15, 2026. If enacted in its current form, the amendment would make three key changes: expanding the government exemption to cover anticorruption operations, introducing a statutory definition of “government agency,” and restructuring the lawful bases for personal data processing to align with international standards. Background The PDPA has encountered several enforcement challenges since its implementation, including three core problems identified by the bill’s sponsors: (1) the current exemptions for government agencies do not cover anticorruption and misconduct-prevention operations; (2) the PDPA lacks a clear statutory definition of “government agency,” causing legal uncertainty as to which entities are covered; and (3) the existing framework for lawful bases of data processing does not align with international standards—particularly the multiple-lawful-bases system in the EU’s General Data Protection Regulation (GDPR)—making compliance inflexible for both government and private sector entities. Expanded Government Exemption The current PDPA exempts government agencies performing duties related to national security (including fiscal security), public safety, anti-money laundering, forensic science, and cybersecurity. The proposed amendment adds “prevention and suppression of corruption and misconduct” to this list of exempted functions. This would allow anticorruption bodies—most notably the National Anti-Corruption Commission (NACC), which is identified as a directly affected party—to collect, use, and disclose personal data without being subject to PDPA requirements when carrying out their duties. New Statutory Definition of “Government Agency” Notably, while the current PDPA use the term “government agency” in several provisions, the term is not comprehensively defined, creating potential uncertainty as to its scope. The draft bill therefore

On July 23, 2026, the Bank of Thailand (BOT) released for public comment its draft Notification on Digital Channel Security, which would significantly expand the scope and stringency of Thailand’s existing mobile banking security framework. If finalized in its current form, the draft notification would extend mandatory security requirements to credit card providers and credit providers, cover internet banking in addition to mobile applications, phase out SMS one-time passwords (OTPs) for transaction authentication, and introduce biometric verification requirements for high-value transactions. The public comment period is open through August 24, 2026. Background The BOT’s existing Mobile Banking Security Notification, issued in 2024, sets minimum security standards for financial institutions, specialized financial institutions (SFIs), and e-money providers, significantly reducing “money-draining app” fraud. However, fraudsters have since shifted to nonbank providers and internet banking channels, prompting the BOT to propose broader security requirements. Expanded Scope of Regulated Entities and Channels The existing Mobile Banking Security Notification covers only financial institutions, SFIs, and e-money providers offering mobile banking services. The draft expands coverage in two key areas: entities and channels. On the entity side, it adds credit card providers and credit providers that offer fund transfers to third parties at other financial service providers or that provide cash withdrawal services to individual retail customers. On the channel side, it broadens coverage to include internet banking in addition to mobile banking. Strengthened Customer Authentication The draft introduces enhanced authentication requirements in three areas: Service enrollment and device changes. Providers must implement rigorous identity verification, notify customers of enrollment results through out-of-band communication channels, and adopt risk-mitigation measures such as cooling-off periods and temporary transaction limits. Transaction-level authentication. Providers must use two-factor authentication for fund transfers, cardless ATM withdrawals, and transaction limit increases. Secure authentication factors. Key requirements include the following: “What-you-know” factors must

Data protection officers (DPOs) have become a fixture of Thailand’s privacy compliance landscape since the Personal Data Protection Act B.E. 2562 (2019) (PDPA) took full effect and the Office of the Personal Data Protection Committee (PDPC) began requiring certain organizations to appoint them. On July 7, 2026, the Office of the PDPC presented draft guidance on DPOs as part of a public consultation on a series of draft personal data protection manuals and recommendations. The draft offers the clearest indication yet of how the regulator expects the DPO role to work in practice, addressing recurring implementation issues under the PDPA—including when an organization must appoint a DPO, how the DPO should operate independently, how to manage conflicts of interest, and how data subjects and regulators should be able to contact the DPO. Because it remains in draft, organizations have an opportunity to weigh the practical implications now before the guidance is finalized. When a DPO Must Be Appointed The draft guidance clarifies the triggers for mandatory DPO appointment, including: Regular and systematic monitoring of personal data or systems on a large scale, such as tracking, analyzing, or predicting behavior, attitudes, or individual characteristics. Core activities involving large-scale processing of sensitive personal data, such as health data, biometric data, or criminal records. Certain foreign-organization representative arrangements. Public-sector coverage under relevant notifications identifying government entities that must appoint a DPO. Processing involving 100,000 or more data subjects may be considered large-scale. The guidance also contemplates voluntary DPO appointment for organizations that wish to raise their privacy governance standards, and such organizations should still comply with the standards applicable to DPOs under the law. Independence and Reporting Lines The draft guidance identifies lack of DPO independence as a core risk because an ineffective or constrained DPO may be unable to raise deficiencies

Vietnam’s new E-Commerce Law, which took effect on 1 July 2026 along with its implementing Decree No. 248/2026/ND-CP (Decree 248), marks a significant development in the country’s approach to online intellectual property (IP) enforcement, reflecting a clear shift from a reactive model of intermediary liability to one that expects platforms to play a more active role in preventing infringement. From notice-and-takedown to platform responsibility The most significant change introduced by the E-Commerce Law is the transformation of the legal role of e-commerce platforms. The existing safe harbor provisions under the IP Law and the copyright notice-and-takedown regime established by Decree 17/2023/ND-CP (Decree 17) largely required intermediaries to act only after receiving notice of infringement. Once infringing content had been removed, the platform’s legal obligation was generally considered fulfilled. The new legislation adopts a fundamentally different approach. Article 17 of the E-Commerce Law requires intermediary platforms to screen information relating to goods and services before publication in order to prevent listings involving counterfeit or IP-infringing goods, and goods of unknown origin. Rather than relying exclusively on complaints from rights holders, platforms are now expected to implement preventive measures before infringing listings become publicly available. Decree 248 further requires platforms to update keyword filters based on recommendations issued by competent authorities. These filtering mechanisms are intended to prevent prohibited listings from appearing on the platform and represent a further move away from a purely complaint-driven enforcement model. The legislation also introduces Vietnam’s first statutory stay-down obligation. Under the E-Commerce Law and Decree 248, major digital platforms must maintain automated systems capable of reviewing, warning against, and removing unlawful listings while also implementing measures to prevent repeat violations, defined under Decree 248 as conduct that has previously been identified and handled by the platform, but continues to recur. This obligation addresses one
