Chinese studies of International Relations constitute today an integral part of the claim of IR as a global discipline. This paper starts by providing a critical evaluation of the contribution made by the so-called ‘Chinese School of IR’ to the global production of knowledge. Against this background, it teases out a curious case of ‘schools of IR’ as commonly labelled in the global IR theoretical conversation and looks at how such labels have been used by the ‘core’ to create a parallel but explicitly inferior universe of knowledge production to localize theoretical noises from the ‘peripheries’. Situating the Chinese School of IR in such global context, it considers how ‘school’ label has been proactively appropriated by Chinese scholars to engage in a purposely contentious politics in the disciplinary IR, which questions the claim of the American ‘core’ as the creator, depositor, and distributor of universal knowledge, and seeks to unveil the geo-historical linkage between the political and the epistemic. School labelling therefore matters, it is argued, because it has become a site of contestation of geopolitics of knowledge and reflects the perils and promises in our collective pursuit of constructing a truly global IR.
