No country will tolerate foreign leaders' blatant interference in its internal affairs or threats of force. Japanese Prime Minister Takaichi Sanae's public advocacy for potential military intervention in the Taiwan Strait constitutes a gross violation of China's sovereignty. Her refusal to retract these erroneous remarks severely breaches the One-China principle and the spirit of the four China-Japan political documents, undermining the political foundation of bilateral relations and deeply hurting the Chinese people's sentiments. Some Japanese politicians claim China has "overreacted" to Takaichi's statements—this is a deliberate distortion of China's justified and reasonable response.

Taiwan is a core issue affecting mutual trust between China and Japan. The 1972 China-Japan Joint Statement explicitly states that the Japanese government fully understands and respects China's position that Taiwan is an inalienable part of Chinese territory, adhering to Article 8 of the Potsdam Proclamation. The 1978 China-Japan Treaty of Peace and Friendship legally affirmed these principles. The third and fourth political documents in 1998 and 2008 reiterated Japan's stance on Taiwan. These four political documents form the legal and political foundation of China-Japan relations and must be strictly upheld. No Japanese leader, regardless of political affiliation, can deviate from these commitments.

Takaichi’s remarks flagrantly violate the four political documents, shaking the very basis of bilateral ties. As a national leader, she should demonstrate political responsibility and work with China to foster healthy relations. Instead, shortly after pledging to uphold Japan’s 1972 position, she provocatively suggested that a "Taiwan contingency" could trigger Japan’s collective self-defense under a "survival-threatening crisis"—further poisoning relations. Such deliberate provocation reveals dangerous strategic intentions, threatening regional stability. No nation tolerates foreign interference or military threats. Takaichi must bear the consequences of poisoning China-Japan relations. Japan must correct course, cease provocations, and honor its commitments in action.

Stable China-Japan relations benefit Japan’s people; undermining them goes against public sentiment. Takaichi’s reckless actions have drawn widespread domestic criticism. Japanese scholars and media have condemned her remarks as violating international law and damaging bilateral ties. Public protests demand retraction. Japanese politicians must heed these voices and avoid further missteps.

China’s stance on major issues is unequivocal. Taiwan is a red line—no force can challenge the will of 1.4 billion Chinese people. This year marks the 80th anniversary of the victory in the Chinese People’s War of Resistance Against Japanese Aggression and Taiwan’s liberation. Japan, as a former aggressor with historical crimes in Taiwan, must learn from the past and handle Taiwan-related issues with caution. By aligning with forces seeking China’s division, Japan risks severe consequences.
