Thailand’s Office of the Personal Data Protection Committee (PDPC) recently released draft guidance on records of processing activities (ROPA) for personal data controllers and processors under the Personal Data Protection Act B.E. 2562 (2019) (PDPA). The draft guidance, which was presented to the public on July 7, 2026, addresses both controller records of collection, use, and disclosure of personal data and processor records of processing activities carried out on behalf of controllers. If implemented, the guidance will significantly expand organizational expectations for ROPA preparation, maintenance, and use across all sectors. Key Takeaways The draft guidance contains several important implications for organizations subject to the PDPA: ROPA reframed as a core accountability tool. The guidance elevates ROPA from an administrative record to a central accountability mechanism, connecting controller duties with recordkeeping obligations. ROPA as a source for privacy notices and governance documents. ROPA should serve as the primary source for privacy notices and align with consent management, retention schedules, DPIAs, incident response plans, and vendor contracts. Expanded scope across all activities. ROPA must cover all processing activities across the organization—including security, finance, HR, and external contractors—with correct controller or processor classification for each. Ongoing maintenance and auditability. ROPA must be updated for any change to systems, purposes, or processors, reviewed at least annually, and maintained with version control and a designated owner. Enhanced vendor, processor, and cross-border transfer requirements. Organizations must document all processors, external recipients, and cross-border transfers, specifying purposes, access scope, and destination countries. Linkage with risk assessment, DPIAs, and LIAs. ROPA should assign risk levels to each activity and identify when data protection impact assessments (DPIAs) or legitimate interests assessments (LIAs) are required, functioning as a risk-management tool. ROPA and data breach readiness. Incomplete ROPA can delay breach response and notification. Organizations should map data flows, vendors,

On June 17, 2026, Indonesia’s National Agency of Drug and Food Control (BPOM) issued BPOM Regulation No. 10 of 2026 on Nutritional Information on Processed Food Labels. The new regulation, which revokes three previous nutrition labeling regulations, introduces several notable changes affecting food and beverage manufacturers, importers, and distributors. These changes range from updated nutrient reference values and serving-size requirements to the introduction of the Nutri-Level front-of-pack labeling system for certain beverage products. Businesses operating in Indonesia should carefully review these developments and assess their products’ compliance with the new requirements during the transition period. Implementation of the Nutri-Level Labeling System To implement the recently issued decree on Nutri-Level labeling, BPOM Regulation No. 10 of 2026 stipulates the requirements to implement the Nutri-Level labeling system on the front-of-pack. Under the new framework, ready-to-drink beverages, powdered beverages, and liquid or solid concentrates are required to display Nutri-Level labeling on the front label of their packaging. The Nutri-Level labeling system classifies products into color-coded levels A through D based on their sugar, sodium, and total fat content. The applicable Nutri-Level is determined based on the lowest level measured in the assessment of sugar, sodium, and total fat content. For products classified as level C or D, the Nutri-Level label must be accompanied by information on the relevant sugar, sodium, and total fat content per 100 ml of the ready-to-consume product. Products classified as level A or B may either display only the Nutri-Level designation or display the Nutri-Level together with the relevant nutritional information per 100 ml. Minimum Vitamin and Mineral Content Required for Declaration BPOM Regulation No. 10 of 2026 introduces a stricter threshold for the declaration of vitamins and minerals in the nutritional value information section (ING). Vitamins or minerals may only be declared if they are present at a

The drug registration process in Vietnam will be simplified, particularly for foreign applicants, following the recent issuance by Vietnam’s Ministry of Health (MOH) of a new circular that is expected to reduce administrative hurdles. Circular No. 32/2026/TT-BYT on the registration of drugs and medicinal ingredients (Circular 32) was issued on July 29, 2026, and will take effect on October 1, 2026, replacing Circular No. 12/2025/TT-BYT. Key provisions of the new circular are discussed below. Five-Year Data Exclusivity and Five-Month Public Disclosure Framework Circular 32 updates data protection guidelines by explicitly referencing Article 128 of the amended Intellectual Property Law, which sets out that new drugs supported by clinical trial data submitted for the first time will be granted a five-year data exclusivity period from the date of the initial marketing authorization (MA) approval. Subsequent applications that rely on the originator’s protected data will not be eligible for approval from the date of submission of the originator’s registration dossier until five years after the first MA is granted. Furthermore, in accordance with the new regulations, the regulatory authority must publicly disclose information on subsequent applications five months before the granting of MA, providing originator companies with an opportunity to exercise and enforce their intellectual property rights. Simplified Requirements for Foreign Legal Documents Circular 32 expands the circumstances under which legal documents issued by foreign authorities are exempt from consular legalization and authenticity verification requirements. Specifically, such documents may be exempt if the Drug Administration of Vietnam (DAV) is able to verify their authenticity directly through official electronic means, including written confirmation or email correspondence sent directly to the MOH by the competent foreign authority, or publicly accessible English-language databases maintained by recognized foreign regulatory authorities. In addition, the new circular permits the submission of electronic notarized copies of legal documents

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
