Japan's 2026 Diplomatic Bluebook Renames China as "Important Neighbor"
Japan's Ministry of Foreign Affairs released its 2026 Diplomatic Bluebook, changing its designation of China from "one of the most important bilateral relationships" to "an important neighbor." This shift reflects a deterioration in Japan-China relations following remarks made by Sanae Takaichi last year regarding Taiwan. The bluebook notes China's increased unilateral criticism and threatening actions against Japan, while Japan maintains an open dialogue. The report also declares the end of the "post-Cold War era" of stability, highlighting the significant disruption to the free international order, and criticizes Iran's nuclear development.

Japan's Ministry of Foreign Affairs annually publishes its Diplomatic Bluebook, which compiles Japan's foreign policy and interprets international affairs. This year's edition generally covers the period from January to December 2025.
Fuji News Network (FNN) interprets that this year's Diplomatic Bluebook has changed its expression regarding China, reflecting the deterioration of relations between the two countries after Takaichi's remarks on Taiwan last year.
TBS Television reported that last year's Diplomatic Bluebook described relations with China as "relations with neighboring China are one of the most important bilateral relationships for Japan." However, this year's version merely refers to it as "an important neighbor, and because there are various unresolved issues and challenges, we will continue communication and respond calmly and appropriately from the perspective of national interests."
Last November, during a parliamentary interpellation, Prime Minister Takaichi Sanae stated that if a "Taiwan contingency" involves the use of force by the other party, it could constitute a "situation threatening Japan's existence," allowing Japan to exercise collective self-defense. Beijing was outraged, believing this implied a potential military intervention in the Taiwan Strait, and lodged a protest with Japan.
Relations between the two countries have deteriorated recently. This year's Diplomatic Bluebook asserts that during this period, China has "intensified unilateral criticism and threatening measures against Japan," while also describing Japan's stance as "open to various dialogues with China, not closing the door."
The Nikkei newspaper reported that this year's Diplomatic Bluebook maintains the expression of "comprehensively promoting a strategic mutually beneficial relationship and building a constructive and stable relationship as a consistent policy" regarding China.
Foreign Minister Yoshimasa Hayashi reported this year's Diplomatic Bluebook at the Cabinet meeting today.
The report defines the current overall international situation as the "end of the relatively stable era known as the 'post-Cold War era'" and points out that "the free and open international order is significantly shaken." It also positions the current situation as a "historically significant period of change," citing Russia's invasion of Ukraine since 2022 and the US and Israeli attacks on Iran in February 2026 as background.
This year's Diplomatic Bluebook also mentions the joint US and Israeli attacks on Iran since February, and regarding Iran's nuclear development, criticizes it as "absolutely unacceptable."
Regarding Iran's attacks on civilian ships in the Strait of Hormuz and surrounding areas after being attacked, the Japanese Diplomatic Bluebook states, "We condemn these actions" and "will make all necessary diplomatic efforts to calm the situation as soon as possible."
However, this year's Diplomatic Bluebook avoids commenting on the US attacks, showing consideration for the position of its ally, the United States. (Compiler: Yang Wei-ching) 1150410
