Legal regulation of digital data sovereignty in cloud computing: International experience and lessons for Vietnam

Abstract

Cloud computing weakens the traditional relationship between data, territory, and jurisdiction. This article conceptualizes digital data sovereignty as the legal and technical capacity to determine conditions governing data access, processing, transfer, auditing, and protection rather than equating sovereignty solely with domestic data-storage requirements. It compares regulatory approaches in the European Union, China, and the United States and evaluates Vietnam’s framework under the 2024 Law on Data, the 2025 Law on Personal Data Protection, the 2025 Law on Cybersecurity, and related legislation. Vietnam has established mechanisms for data classification, impact assessment, cross-border data-transfer control, and cybersecurity. However, gaps remain in cloud-specific regulation, coordination among relevant laws, and mechanisms for resolving jurisdictional conflicts. The article recommends a risk-based governance approach integrating legal safeguards, technical controls, and data-subject rights.
