In 2025, Chinese state media and diplomatic accounts intensified efforts to undermine Japan’s position as a defense partner in the Indo-Pacific, according to research from Japan Nexus Intelligence and ASPI. While past strategies relied on covert networks, the current approach utilizes overt, state-linked channels, allowing China to project narratives more convincingly and with wider reach, particularly in Southeast Asia and the Pacific. This shift reduces operational risk and enhances the credibility of China’s messaging.
The EU’s 2023 report highlighted that using formal channels for content distribution was prevalent, echoing findings that Chinese diplomatic accounts amplified state media to target narratives against Japan. A notable campaign emerged against Japanese Prime Minister Sanae Takaichi following her comments on a potential military response to a Chinese attack on Taiwan.
China’s narratives often exploit historical grievances centered on the 80th anniversary of WWII, arguing that Japan’s defense partnerships threaten regional peace and suggesting a remilitarization. This anti-Japan sentiment specifically targets countries like the Philippines and Fiji, framing their defense arrangements with Japan as provocative.
Throughout 2025, Chinese narratives surged, framing Japan’s defense activities in historical contexts to link past aggression to present militarization. State media portrayed Japan as endangering stability in the Indo-Pacific while characterizing China as a peace-loving nation. Criticism of Japan’s military exercises and defense collaborations further aimed to isolate regional partners from collaborating with Japan and the U.S.
China’s overt messaging strategy is more effective due to its perceived legitimacy, complicating rebuttals from Indo-Pacific governments. As tensions rise, Japan and its allies must navigate this evolving landscape of influence, emphasizing transparent and proactive communication to counter China’s disinformation while reinforcing regional stability.
