Japan Revises China Ties in 2026 Diplomatic Bluebook

Japan plans to revise its official characterization of relations with China in its upcoming annual diplomatic report, signaling a notable cooling in bilateral ties amid escalating tensions. The 2026 Diplomatic Bluebook, a draft of which was reviewed by journalists, removes the longstanding description of China as one of Japan's most important partners. Instead, it will refer to China as an important neighbor, while describing the relationship as strategic and mutually beneficial. Prime Minister Sanae Takaichi's government is expected to approve the document next month.

The shift reflects a year of heightened frictions between Tokyo and Beijing. The draft highlights several incidents, including Chinese export controls on rare earths and critical minerals essential for electronics manufacturing, radar lock-ons by Chinese forces targeting Japanese military aircraft, and intensified military activities around Taiwan. These confrontations have contributed to a broader deterioration in relations, particularly since November, when Takaichi stated that Japan could deploy its military if a Chinese action against Taiwan also endangered Japanese territory.
