Vietnam has taken a significant step in regulating its e-commerce sector with the issuance of a new decree guiding the country’s recently enacted Law on E-Commerce. Decree No. 248/2026/ND-CP, issued on June 30, 2026, and taking effect the following day, addresses mandatory platform policies, registration requirements for offshore platforms, additional obligations on platform operators, and market access conditions for foreign investors. Mandatory Policy Contents The decree sets out detailed guidance on the required contents of various platform policies, covering pricing, payment, display priority, livestream sales, delivery, returns, method of service provision, and service termination and refunds. Clarification of Obligations for Platform Operators The decree provides clarification of the obligations applicable to platform operators. Notably, intermediary e-commerce platform operators with online ordering functions must: Collect specific information to implement electronic identity verification of sellers; Cooperate with regulators by reporting online through the state e-commerce management system and by blocking, suspending, or removing content upon request of a competent authority; Maintain a mechanism to store contract data, including price, product or service information, and parties’ information, for at least three years from the date of contract conclusion; and If qualifying as a “large digital platform” under consumer protection law, maintain an online system for receiving and handling complaints and requests, and comply with enhanced content-removal requirements. Registration Requirements for Offshore Platforms Offshore e-commerce platforms, whether direct-sales, intermediary, social-network-based, or integrated, that conduct e-commerce activity in Vietnam must register with the Ministry of Industry and Trade if the platform: Allows Vietnamese-language selection; Uses a “.vn” domain; or Reaches 100,000 or more transactions with Vietnam-based buyers within a calendar year. Notably, the registration requirement now captures not only traditional intermediary platforms, but also direct-sales platforms. Foreign Investment Conditions Foreign investors holding a controlling interest in an intermediary e-commerce platform, a social media platform

Vietnam has introduced an official list of high-risk AI systems, triggering more stringent compliance obligations for developers, suppliers, and deployers operating in the country. On June 30, 2026, the prime minister issued Decision No. 33/2026/QD-TTg (Decision 33), which establishes the List of High-Risk AI Systems under the Law on Artificial Intelligence (AI Law) and Decree No. 142/2026/ND-CP (Decree 142). Decision 33 takes effect on August 15, 2026. Decision 33 is significant because only AI systems included on the list will be subject to the heightened compliance obligations applicable to high-risk AI systems under the AI Law and Decree 142. These include, among others, local presence requirements for foreign providers, mandatory conformity assessment before deployment, comprehensive risk management and data quality documentation, and strict liability for damages even when the provider is fully compliant. Decision 33 also specifies the applicable conformity assessment pathway for each listed system, indicating whether the system must undergo mandatory third-party conformity certification before being placed into use, or whether the provider may self-assess conformity or voluntarily engage a registered or recognized conformity assessment body. Which AI Systems Are Covered? Decision 33 identifies high-risk AI systems across six sectors—the key attributes of which are summarized below. Education: AI systems used for automated assessment, learner ranking, behavioral monitoring, or generating educational content from uncontrolled data sources. Ethnic affairs and religion: AI systems used to automatically score, classify, or rank applications for government ethnic policies; approve or reject regulatory applications; suspend benefits on suspicion of fraud; allocate budgets; or infer and classify individuals by ethnicity or religion for administrative purposes. Healthcare: AI-assisted surgical systems and autonomous AI-powered surgical robots. Banking: AI systems that autonomously conduct electronic banking transactions or make credit approval decisions. Judicial proceedings: Certain large-scale biometric identification systems used in public-interest civil proceedings. Transport: Thirty-one categories

Vietnam has taken a decisive step into the global artificial intelligence regulatory landscape with the promulgation of the Law on Artificial Intelligence No. 134/2025/QH15 (AI Law), adopted on December 10, 2025, and effective from March 1, 2026. As one of the earliest comprehensive, standalone AI statutes in Southeast Asia, the AI Law signals Vietnam’s ambition to position itself as both an innovation-friendly and governance-conscious AI market. In doing so, the legislature has also streamlined Vietnam’s AI regulatory architecture. The AI Law repeals most AI-related provisions previously embedded in the Law on Digital Technology Industry No. 71/2025/QH15, consolidating AI governance under a single, unified legal framework. This structural move underscores an intent to provide greater regulatory clarity and coherence for businesses operating across the AI value chain. Against this backdrop, the key question for AI developers, providers, deployers, and governance teams is how the new risk-based framework will shape compliance expectations, operational decisions, and governance design in practice. This article examines the new AI Law through that practical lens, focusing on what it means for AI businesses operating in or into Vietnam. Scope of Application The AI Law applies broadly to Vietnamese organizations and individuals, as well as foreign entities that participate in AI-related activities within Vietnam. The law expressly excludes AI activities conducted solely for national defense, security, and cryptography purposes. A defining feature of the AI Law is that it regulates by role, not by industry. It distinguishes between: Developers, who design, build, train, test, or fine-tune AI models and have direct control over the technical methods, training data, or model parameters; Providers, who place AI systems on the market or put them into use under their own names; Deployers, who use AI systems under their control in professional, commercial, or service-provision activities; Users, who interact with AI
