Japan has revised its official language describing its ties with China in the 2026 edition of its annual foreign policy report, moving from the description in the 2025 report that labeled the relationship as "one of the most important bilateral relations" to referring to China as "an important neighbor." The change, published Friday in the Diplomatic Bluebook, signals a shift in tone amid persistent tensions between the two countries over differing views on Taiwan.
Despite the adjustment in wording, Tokyo made clear that it intends to maintain channels of communication with Beijing. The Bluebook repeats a pledge to continue efforts to improve relations and to engage calmly and deliberately on issues affecting national interests.
Japanese Foreign Minister Toshimitsu Motegi commented on the report on Friday, noting that "changes occur annually across many fields." He said Tokyo will seek a strategic and mutually beneficial relationship with China, aim to build constructive and stable ties, and remain open to dialogue with Beijing.
The document and officials' remarks come against a backdrop of heightened friction in recent months. Tensions escalated after Japanese Prime Minister Sanae Takaichi said a Chinese invasion of Taiwan may be considered a legal justification for Tokyo to deploy troops. China, which regards Taiwan as its territory, has responded with measures including warnings to its citizens against travel to Japan, the imposition of trade restrictions, and public accusations that Japan is fostering militarism.
The Bluebook also follows a diplomatic incident in late March when an active member of Japan's Self-Defense Forces was arrested for breaching the grounds of the Chinese embassy in Tokyo. Such incidents have underscored the strains in bilateral ties even as Tokyo reiterates its intention to pursue dialogue.
On the path forward, the 2026 Bluebook states: "it is precisely because there are various issues and challenges that we will continue communicating and respond calmly and appropriately from the viewpoint of our national interest." The passage underscores Tokyo's approach of coupling candid appraisal of the relationship with a stated commitment to sustained engagement.
Summary - The 2026 Diplomatic Bluebook downgrades the description of Japan-China relations but stresses continued communication and a desire for a strategic, mutually beneficial relationship.
