Cross-Border Data Flows and Digital Sovereignty: Legal Dilemmas in Transnational Governance

This article aims to explore the legal dilemmas arising from the intersection of cross-border data flows and digital sovereignty within the evolving landscape of transnational governance. Using a narrative review approach and a descriptive analysis method, this study synthesizes recent academic literature, international legal instruments, regional regulations, and national policies published between 2020 and 2024. The sources include peer-reviewed legal scholarship, policy documents from international organizations, and national legislative texts. The analysis focuses on the conceptual foundations of cross-border data movement and digital sovereignty, the legal frameworks governing data governance, and the challenges of harmonizing national interests with global connectivity. The study draws upon legal theory and comparative regulatory analysis to critically examine multilateral initiatives and national responses. The study finds that cross-border data flows are essential to digital trade, innovation, and global interconnectivity, yet they increasingly face legal constraints due to states’ pursuit of digital sovereignty. This pursuit manifests in data localization laws, extraterritorial enforcement of domestic regulations, and strategic decoupling efforts, particularly among major geopolitical actors. International and regional efforts at harmonization—such as those by the OECD and G20—offer frameworks for trust-based data governance but remain hindered by divergent regulatory philosophies. Fragmentation of legal norms has resulted in significant compliance challenges and enforcement dilemmas, while human rights protections in data governance vary widely across jurisdictions, affecting privacy and freedom of expression. Effective governance of cross-border data flows requires a balance between national sovereignty and transnational cooperation. Moving forward, interoperability and mutual legal recognition offer viable alternatives to legal uniformity or isolation.
