This episode examines the fast-evolving Russia–China partnership, notably the security links, and considers the implications this cooperation has for the Euro-Atlantic community as it seeks to simultaneously manage security threats in the Indo-Pacific and Euro-Atlantic regions. Over the past decade the relationship between China and Russia has broadened and deepened, and now covers cooperation on security, energy and economic issues and diplomacy, as well as developing into the realm of technology. Dr Elizabeth Wishnick, Associate Professor of Political Science at Montclair State University and Adjunct Associate Research Scholar at the Weatherhead East Asian Institute, Columbia University, and Dr Marcin Kaczmarski, Lecturer in Security Studies at the University of Glasgow, discuss the scope and drivers of the Sino-Russian relationship, how far the partnership can develop, and how the Euro-Atlantic community should best respond with Dr Neil Melvin, Director RUSI International Security Studies.
