[STUDENT POLICY BRIEF] What specific measures could the US, the European Union and China take in order to foster and facilitate cross-border data flows?

By Veronica Arroyo, Karin Hess, Nicole Grünbaum & Gustavo Ribeiro


The Digital, Governance and Sovereignty Chair publishes, on a regular basis, the finest essays and papers written by Sciences Po students in the course of their studies.

This Policy Brief has been selected as one of the best works written during the course taught by Pr Florence G’sell “Comparative Approach to Big Tech Regulation” in Spring 2023.


This policy brief is addressed to the G20 Digital Economy Ministers and tackles the primary question: what specific measures could the US, the European Union and China take in order to foster and facilitate cross-border data flows? For this, it explores the principles and rationales that influence the regulation of data flows, and discusses the instruments that allow for data to flow across the People’s Republic of China’s, the European Union’s and the United States of America’s borders.

In doing so, it finds convergent and divergent points. The EU and the US have limited overlaps in regulation of data protection and privacy. Moreover, both polities diverge from China when it comes to national security, as the latter has legal means to restrict cross-border data flows on security grounds. The trade of digital goods and services is a priority for all three polities alike.

This policy brief advises the G20 Digital Economy Ministers to adopt stabilizing measures such as repositories, standards, and standard contractual clauses, and explore transformative measures including privacy-enhancing technologies, legally adequate data hubs in free trade zones, and a court with transnational jurisdiction.
