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 On July 7, 2026, the Office of the PDPC presented draft guidance on DPOs as part of a public consultation on a series of draft personal data protection manuals and recommendations.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 When a DPO Must Be Appointed The draft guidance clarifies the triggers for mandatory DPO appointment, including: Regular and systematic monitoring of personal data or systems on a large scale, such as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 Independence and Reporting Lines The draft guidance identifies lack of DPO independence as a core risk because an ineffective or constrained DPO may be unable to raise deficiencies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

A new decree on penalties for violations related to the crypto asset market creates compliance risks for offshore crypto asset exchanges in Vietnam that do not hold, and practically cannot obtain, a Vietnamese license, and for Vietnamese users who continue to transact on those platforms. Decree No. 284/2026/ND-CP (Decree 284), issued by the government of Vietnam on July 16, 2026, formally establishes an administrative penalty framework for violations related to crypto assets and the crypto asset market. The decree takes effect on September 1, 2026, and will remain in force for the duration of the five-year pilot program under Resolution No. 05/2025/NQ-CP, which is scheduled to end in September 2030. Direct Penalties on Vietnamese Users The most immediate commercial risk to offshore platforms is that their Vietnamese users now face direct personal liability for using their exchanges. Vietnamese users who trade crypto assets outside of a Ministry of Finance-licensed service provider face fines of up to VND 50 million (approximately USD 1,900). Vietnamese users trading in crypto assets that are offered or issued to foreign users face higher penalties of up to VND 100 million (approximately USD 3,800). It is expected that Vietnamese users will be more willing to migrate away from offshore platforms now that there is a risk of real enforcement against them. Penalties on Unlicensed Service Providers Violations of providing crypto asset services or advertising crypto-related services without a license face fines of up to VND 200 million (approximately USD 7,700). Operating a crypto asset trading market without proper authorization falls within the same highest penalty bands. Organizations that violate issuance, provision, or disclosure rules may face fines of up to VND 200 million. Although the maximum administrative fine per violation is capped at VND 200 million for organizations and VND 100 million for individuals, these

As food innovation continues to accelerate, manufacturers are increasingly introducing ingredients derived from new sources, produced using novel technologies, or lacking a significant history of human consumption. While these innovations create new opportunities for the food industry, they also raise important questions regarding consumer safety. For this reason, many jurisdictions, including Thailand, the European Union, Australia and New Zealand, Canada, and Singapore, require a premarket safety assessment for novel food ingredients before they can be placed on the market. The objective of this assessment is to ensure that each ingredient is safe for its intended use and level of consumption, does not present toxicological, allergenic, microbiological, or nutritional concerns, and will not mislead consumers. Scientific authorities typically evaluate the ingredient’s identity, manufacturing process, composition, specifications, anticipated dietary exposure, toxicological information, nutritional impact, and history of use before determining whether it can be marketed. Against this background, the Thai Food and Drug Administration (FDA) recently took an important step toward improving regulatory transparency by publishing, for the first time, a consolidated public list of substances that have successfully completed the Thai FDA’s safety assessment process, including substances determined to be novel foods and those determined not to fall within the novel food category. The list identifies the approved substances, the corresponding manufacturers or importers, approval dates, and the approved conditions of use. Although the publication does not change the existing legal framework governing novel food approvals, it provides businesses with greater visibility into the Thai FDA’s regulatory precedents and the types of substances that have previously been accepted through the safety assessment process. The full announcement is available on the Thai FDA’s website. As the list is now publicly available, it also provides useful insight into the types of substances that have successfully completed the Thai FDA’s safety assessment process.
