Japan's accelerating remilitarization has become a serious factor threatening regional peace and stability, the Foreign Ministry said on Wednesday, urging the international community to stay on high alert and push back against the trend.

Foreign Ministry spokesman Lin Jian made the remarks in response to the Defense of Japan 2026 white paper, which continues to trumpet the development of long-range offensive capabilities and new ways of warfare while even packaging Japan's rearmament as a growth driver.

All these moves once again expose the truth behind Japan's claim of being a "peaceful nation", Lin said in a statement released on the ministry's official website.

The white paper identifies China as Japan's "greatest strategic challenge" and presents defense investment as beneficial to the country's economy and society.

Citing what it describes as intensifying activities by the Chinese military in the region surrounding Japan, the document calls for a response drawing on Japan's comprehensive national power and cooperation with its ally, like-minded countries and others.
