The rise of digital information communication technology has major implications for how states wield coercive power beyond their territorial borders through the extraterritorial geographies of data flows. In examining the geopolitics of data, transnational surveillance, and jurisdiction, this collection makes a significant contribution to the field of global internet governance. It shows how the internet is a forum for geopolitical struggle with states weaponising jurisdiction and exerting power beyond their own borders directly, and via infrastructures owned and operated by transnational technology companies. These dynamics challenge existing conceptual and theoretical categories of contemporary law across the fields of international relations, criminology, and digital media, and raise urgent questions about if and how individual rights can be protected in an era of ubiquitous transnational surveillance conducted by private companies and governments alike.
