This chapter uses securitisation theory to explain recent trends in the Pacific region. We distinguish between two narratives-a traditional security narrative that foregrounds the role of great powers and regional allies and a climate-security narrative used in multilateral advocacy. The former largely sees Pacific states as ‘objects’ of great-power politics while the latter has tended to be championed by islanders themselves. As tensions between China and the United States have escalated, these two narratives have begun to intertwine as Pacific states are increasingly using climate action as a bargaining tool in their negotiations about traditional security threats.
