She investigates the principles, rationales and shifting dynamics of collaboration on a range of security issues, and their consequences for China, the EU and other regions. She pays particular attention to EU–China relations in the realm of anti-terrorism, anti-piracy and energy security, and disentangles their cooperation efforts in the context of increasing political and economic tensions. Systematic and accessible, this is an essential guide to the past, present and future of one of the world’s most important, yet most complicated, security relationships.
