The International Relations discipline (IR) is known as an ‘American Social Science’ dominated by scholars and theories from the US core. This paper compares IR in two non-core settings, China and Europe. It shows that there is a growing institutional and intellectual integration into the global Anglophone, mostly American, IR in both Europe and China. Both Chinese and European IR communities have established top Anglophone journals like the European Journal of International Relations and the Chinese Journal of International Politics to spearhead their integration into mainstream Anglophone IR and carve out a space for regional thinking. Yet, the analysis of their publication and citation patterns shows that IR outside the American core communicates like a hub-and-spokes system where there is always a connection to American core but rarely very strong linkages to other peripheral regions. The two journals studied thus function as outlets for ‘local’ and American, rely on ‘local’ and American sources, and there is very little integration and exchange between Chinese and European IR. Chinese and European IR would benefit from such dialogue, especially regarding ‘schools’ of IR at the margins of an ‘American social science’.
