Over the past decade, the EU and China have expanded their relations beyond a focus on economic and trade issues to the sphere of security. Taking a broad definition of security, a multidisciplinary approach, and a comparative perspective (including scholars from both Europe and China), this book provides an in-depth analysis of the extent to which the EU and China not only express similar threat concerns, or make declarations about joint responses, but also adopt concrete measures in the pursuance of security cooperation. In particular, the book seeks to explore a range of key themes in the field of EU-China security cooperation such as nuclear proliferation, international terrorist threats and cyber attacks. Besides providing an overview of the areas where security cooperation exists and where it does not, it also highlights the aspects of convergence and divergence and the reasons for their occurrence.
