Ally or threat? China’s reaction one to watch as Japan sends out mixed signals in annual diplomatic blue book
- Japanese report reinstates reference to seeking ‘mutually beneficial’ ties with China, but also blames it for ‘severe and complex’ security situation
- One observer says consistent mention of ‘China threat’ washes away positive effect of ‘reintroducing cooperative elements’

Japan released its annual diplomatic blue book last week, where it reinforced the message of building “constructive and stable” ties with China through dialogue.
It also pledged to pursue a “mutually beneficial relationship based on common strategic interest”, reinstating the reference after a gap of five years, echoing a consensus reached between Japanese Prime Minister Fumio Kishida and Chinese President Xi Jinping in November.
Chong Ja Ian, associate professor of political science at the National University of Singapore, said the inclusion of the phrase in the latest blue book showed Japan hoped for cooperation or at least stability in ties with China despite challenges.
“Engagement and dialogue are useful even if there is no agreement. That the Japanese side is extending this possibility is a positive,” Chong said. “Whether [China] will reciprocate is something to watch.”
However, the blue book also contains some sharply phrased criticisms directed at China, including accusations that it poses significant challenges to Japan’s security environment.
