Most international relations (IR) research on the role of collective memory and representations of the past gives the impression that these primarily matter for states constrained internationally by their history as aggressors, such as Japan. How former perpetrator states represent the past is seen as important for bilateral relations because it may affect perceptions in previously victimised states. Representations of the past in the victimised states are seldom dealt with. This article argues that war memory in victimised states is also highly relevant for bilateral relations, since it is closely connected to ontological security, or the security of identity. By analysing Chinese official documents and Japanese parliamentary debates the article shows how the Chinese government has used representations of the past for ontological security purposes, and how in response Japanese political actors have politicised exhibits at Chinese war museums that are seen as a threat to Japanese identity and interests.
