China used its April 15 foreign ministry briefing to attack Japan’s planned deployment of air defence missile units to Yonaguni, accusing Tokyo of using defence rhetoric to build what Beijing called a forward fortress of military confrontation near China.
Foreign Ministry spokesperson Guo Jiakun said Japan’s military posture now goes beyond self-defence and urged the international community to stay alert to what he described as fast-growing remilitarisation and neo-militarism.
The Chinese criticism follows Japanese moves to strengthen military capabilities on islands near Taiwan. Associated Press reported that Japan is deploying upgraded long-range missile systems as part of a wider southwestern defence buildup, while earlier Reuters reporting said Japan had framed the Yonaguni deployment as a deterrent and territorial defence measure.
That gives the story a clear counterparty rationale: China presents the move as dangerous militarisation, while Japan frames it as defensive deterrence tied to regional security risks.
