Personal Data Protection Act: Thai Cabinet Provides Partial Compliance Extension to May 2021

On May 19, 2020, the Thai Cabinet approved the implementation of a royal decree providing a one-year exemption from certain provisions under the Personal Data Protection Act 2019 (PDPA).

The royal decree, once published in the Royal Gazette, will be effective from May 27, 2020, until May 31, 2021. Based on the Cabinet’s announcement, the decree is expected to provide exemption from the following chapters and provisions of the PDPA:

  • Chapter II: Personal Data Protection;
  • Chapter III: Rights of the Data Subject;
  • Chapter V: Complaints;
  • Chapter VI: Civil Liability;
  • Chapter VII: Penalties; and
  • Section 95: Grandfather provision.

A wide-ranging list of categories should be provided in the decree, identifying operations in the private, public, and social enterprise sectors that qualify for the exemption. In the current draft, these businesses include, for example, banking, commercial, communications and telecommunications, construction, digital, education, energy, finance, insurance, medical and public health, professional practices, real estate, tourism, and transportation.

The government anticipates that the extension will give applicable business operators and organizations more flexibility in preparing themselves for compliance with the PDPA. However, it should be emphasized that, during the one-year extension period, businesses should continue to internally roll-out their assessment programs and make use of the time to understand their current practices for handling and processing personal data are, as well as to identify and resolve any compliance gaps. Building awareness of the PDPA within the organization before May 31, 2021, will continue to be essential for PDPA compliance.

It is important to highlight that data controllers must still implement security protection measures for personal data, in accordance with the standards prescribed by the Ministry of Digital Economy and Society.

If you have any questions about the PDPA, the royal decree, and their implementation, please do not hesitate to contact any member of the Tilleke & Gibbins PDPA team, including Athistha (Nop) Chitranukroh at [email protected], Nopparat Lalitkomon at [email protected], or Gvavalin Mahakunkitchareon at [email protected].

On February 17, 2026, Thailand’s Personal Data Protection Committee (PDPC) released its draft Guidelines on Personal Data Protection in the Development and Use of Artificial Intelligence. The draft guidelines, which translate data controller and data processor compliance obligations under the Personal Data Protection Act (PDPA) into measures tailored to AI development and deployment, are open for public comment until February 25, 2026. At a public hearing session on the draft guidelines held on February 19, the PDPC emphasized that its approach to AI is not to hinder innovation but to develop practical guidance supporting safe deployment while ensuring data protection. Although the guidelines are not legally binding, they indicate the regulator’s expectations and the likely direction of interpretation and enforcement. Scope of Application and Role of Stakeholders The guidelines will apply to all data controllers and data processors in Thailand, and to overseas data controllers and data processors whose data processing falls within the extraterritorial scope of the PDPA. The draft guidelines distinguish the roles of parties involved in AI deployment. Users of AI who determine the purpose of use and designate the input data, and retain outputs generated by the AI, are considered data controllers. In contrast, AI model providers or system integrators that process personal data under the instructions of the data controller are generally regarded as data processors. However, if an AI model provider utilizes user data for its own purposes, such as model fine-tuning or training, it may instead be classified as a data controller. Key Obligations for AI Data Collection and Use The basic principles of data processing under the PDPA must be maintained throughout the AI implementation lifecycle, from design to decommissioning, emphasizing accountability and privacy-by-design principles. The draft guidelines also stipulate the following: Data processing agreements (DPAs) should include model training prohibitions,

Data center and cloud investments are forming a major focus of private-sector investment in Thailand, with tech giants like Amazon, Google, Microsoft, and TikTok, as well as numerous telecom and data center companies, committing significant outlays to data center and cloud development. The country’s Board of Investment (BOI) approved projects worth THB 1.87 trillion in 2025, and THB 746 billion of this was from planned data center investments—by far the largest amount from any single industry. Thailand’s swift rise as a regional data center hub is fueled by surging demand for cloud, AI, and digital services, as well as large-scale investments from global tech firms. The country’s strategic location, competitive power costs, robust fiber infrastructure, expanding IT talent, and supportive government policies—including BOI incentives and streamlined approvals—have made it an attractive destination for scalable and sustainable digital infrastructure investments. The BOI’s proactive approach in updating promoted categories and providing both tax and non-tax incentives further ensures Thailand’s continued growth in this sector. 2025 BOI Changes for Data Centers In the middle of 2025, the BOI responded to the remarkable trend by updating investment‑promotion categories across various sectors (e.g., machinery and electrical equipment, public utilities, digital and innovative industries) to accommodate growing investment in data‑center projects. Before the change, which was detailed in a notification that has applied to investment promotion applications submitted from July 1, 2025, onward, data‑center projects under BOI promotion were granted a single A1 incentive (an eight‑year corporate income‑tax exemption) and subject to one uniform set of conditions. The July 2025 notification restructured promotion for data centers into two categories based on power‑usage efficiency: high‑efficiency data centers and other data centers. Under these rules, qualified high‑efficiency data centers are eligible for an eight‑year corporate income tax (CIT) exemption, while for other data centers this exemption is

On November 18, 2025, Vietnam’s Ministry of Finance released for public consultation a draft decree on administrative sanctions in the field of crypto assets and crypto asset markets (the “Draft Decree”), intended to implement Resolution No. 05/2025/NQ-CP dated September 9, 2025, on the pilot crypto asset market in Vietnam (“Resolution 05”). While Resolution 05 sets out who may participate and under what conditions, the Draft Decree addresses a more practical question for market participants, i.e., what happens if those conditions are not met. In doing so, the Draft Decree offers important insight into how Vietnamese regulators intend to supervise, discipline, and ultimately shape the crypto market during the pilot phase. Regulatory Scope and Overall Sanctions Architecture The Draft Decree applies to both domestic and foreign organizations and individuals engaging in crypto-related activities in Vietnam’s market. Covered entities include: (i) crypto asset issuers; (ii) crypto asset service providers, including trading platforms and market operators; (iii) Vietnamese and foreign investors participating in the pilot market; and (iv) other organizations involved in the offering, issuance, or provision of crypto-related services in Vietnam. The breadth of this scope is deliberate. It appears to reflect a regulatory view that cross-border structures, offshore platforms, and indirect participation may not necessarily insulate market actors from compliance obligations once they operate within the pilot framework. For the crypto industry, this may mark a shift from regulatory ambiguity toward a more explicit articulation of jurisdictional reach. At first glance, the Draft Decree’s monetary penalties appear restrained. The maximum fine per administrative violation is capped at VND 200 million (approx. USD 7,700) for organizations and VND 100 million (approx. USD 3,800) for individuals. However, focusing solely on fine levels risks missing the point. The Draft Decree also places great regulatory weight on supplementary sanctions and corrective measures, including: (i)

Thailand’s Data Privacy Day 2026, hosted by the Office of the Personal Data Protection Committee (PDPC), underscored the country’s commitment to strengthening personal data protection, advancing regulatory maturity, and preparing organizations for the next phase of PDPA enforcement. The event marked a clear shift from policy-level compliance toward “Privacy in Action,” signaling that operational readiness and real-world implementation are now priorities. The Office of the PDPC also emphasized that data protection is now a national economic enabler that supports digital trust, competitiveness, and sustainable growth, not just a compliance obligation. The following insights summarize the key takeaways from the Data Privacy Day 2026 event. PDPA in Real Life: What Happens to Your Data Today The Office of the PDPC provided concrete data on enforcement trends and real-world compliance issues facing organizations across Thailand. Complaints and trends. The Office of the PDPC’s Personal Data Protection Act (PDPA) Center recorded 2,672 PDPA-related complaints as of January 2026, with the highest volumes involving failure to comply with the data minimization principle, collection without lawful basis, and use and disclosure without lawful basis. Administrative penalties. Several administrative penalties have been imposed on data controllers and data processors across various sectors, including government, healthcare, retail, SMEs and e-commerce, ranging from tens of thousands to several million baht. Most violations stemmed from weak security measures, failure to notify data breaches within the required timeline, absence of a data protection officer (DPO) when required, and noncompliance with governance requirements such as the Record of Processing Activities (ROPA) and data processing agreements with data processors. Case studies. The Office of the PDPC highlighted specific examples of violations: Hospitals misused personal data for purposes beyond their intended scope (e.g., using personal data collected for providing medical services to send birthday cards) Vendors compromised systems due to inadequate password
