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.
