China-Japan tensions escalate after Tokyo labels Beijing as its 'greatest strategic challenge'
China has formally protested Japan's new defense white paper, which identifies Beijing as a major strategic challenge and addresses the Taiwan issue. Tensions remain high as Japan increases its military capabilities, including the testing of new long-range anti-ship missiles.
Why it matters
The escalating rhetoric between these two major Asian powers highlights growing regional instability and the potential for a shift in the East Asian security balance.
China has lodged a "serious diplomatic" protest with Japan over its latest defence white paper, which portrayed Beijing as Tokyo's "greatest strategic challenge" and made "brazen comments" on Taiwan, further escalating tensions between the two countries.
"The white paper once again targeted China with groundless accusations, rehashing the so-called 'China threat' and grossly interfering in China's internal affairs with brazen comments on China's Taiwan region," Foreign Ministry spokesperson Lin Jing said on Wednesday (August 5, 2026).
"We deplore and firmly reject this, and have lodged serious representations with Japan," he said while answering questions over Japan's new defence white paper.
