This is the first book-length treatment of the advancement of EU global data flows and digital trade through the framework of European institutionalisation. Drawing on case studies of EU-US, EU-Japan and EU-China relations it charts the theoretical and empirical approaches at play. It illustrates how the EU has pioneered high standards in data flows and how it engages in significant digital trade reforms, committed to those standards. The book marks a major shift in how institutionalisation and the EU should be viewed as it relates to two of the more extraordinary areas of global governance: trade and data flows. This significant book will be of interest to EU constitutional lawyers, as well as those researching in the field of IT and data law.
