The book provides an in-depth analysis of EU-China cooperation mechanisms with a focus on efforts to jointly address global challenges. It zooms in on the cooperation mechanisms for addressing three specific global challenges that rank high on the bilateral agenda: mitigating climate change, controlling nuclear non-proliferation and addressing the poverty-insecurity nexus. From this empirical analysis, the book assesses the characteristics and challenges of the EU's emerging "network diplomacy" model of dealing with strategic external relations.
