Coexisting with a powerful and assertive China as a neighbour is a new experience for modern Japan that has long considered itself the only powerful state in east Asia. Interacting with China under this new condition has brought out multiple and competing conceptions of China as it means to Japan. China is an historical rival, a security concern, an indispensable trading partner, an economic competitor and a regional power with competing as well as common interests all at the same time. Japan also sees images of its past self in the pattern of China's rapid development. These ideas of China act both positively and negatively in how Japan conceives and manages its relationship with China, but they also reflect Japan's lack of confidence and shaken sense of history, identity and place in the world. In order to find a way to meaningfully engage with China, Japan needs to recognize its own identity and strength objectively.
