This book presents the very first, interdisciplinarily grounded, comprehensive appraisal of a future "Common European Law on Investment Screening". Thereby, it provides a foundation for a European administrative law framework for investment screening by setting out viable solutions and evaluating their pros and cons. Daimler, the harbour terminal in Zeebrugge, or Saxo Bank are only three recent examples of controversially discussed company takeovers in Europe. The "elephant in the room" is China and its "Belt and Road Initiative". The political will in Europe is growing to more actively control investments flowing into the EU. The current regulatory initiatives raise several fundamental, constitutional and regulatory issues. Surprisingly, they have not been addressed in any depth so far. The book takes stock of the current rather fragmented regulatory approaches and combines contributions from leading international academics, practitioners, and policy makers in their respective fields. Due to the volume's comprehensive approach, it is expected to influence the broader debate on the EU's upcoming regulation of this matter. The book is addressed to participants from academia as well as to representatives from government, business, and civil society.
