China's view on the sanctity of state sovereignty has slowly but inexorably been transformed, and the country has found it difficult to continue to adhere to the principles of non-interference and non-intervention with the same degree of rigour as during the Cold War era. This special section will explore what the principles mean to China today; why and how Beijing has become active in peacebuilding and conflict mediation; and what implication China's approach to the principles has for its position in the global liberal order. This article sets the scene by firstly demonstrating that defining the principles has always been a political act, and secondly offering new discussions about how China's expanding economic power forced the country to more actively engage in politics of conflict-affected regions. Finally, it offers a conceptual framework to explain why and how China has become increasingly active in peacebuilding and conflict mediation.

There is among Chinese international relations scholars an intense debate about how China can protect and promote Chinese global presence and interests while at the same time continue to adhere to the principle of non-intervention. New concepts, distinctions and approaches are developing as the debate progresses. The current Chinese foreign and security policy practice reflects a more flexible and pragmatic Chinese interpretation – and implementation – of the principle of non-intervention with different degrees and types of intervention. This article explores the search for “legitimate great power intervention” characterizing both the debate among Chinese international relations scholars and the current Chinese foreign and security policy practice, and uses this case as the departure point for a more general discussion of the drivers of change – and continuity – in Chinese foreign and security policy.
