Vietnam has enacted a new decree establishing administrative penalties for violations in the fields of cybersecurity and personal data protection. Decree No. 330/2026/NĐ-CP (Decree 330), issued and effective from August 19, 2026, provides a detailed sanctions framework for noncompliance with the Law on Personal Data Protection (including its implementing regulations under Decree 356/2025/ND-CP) and the Law on Cybersecurity, together with their guiding decrees.

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.
