China Intensifies Criticism of Japan Amid Escalating Regional Tensions

China has escalated its criticism of Japan, leveraging historical grievances and contemporary security concerns to challenge Tokyo’s regional role. The campaign, marked by a broad range of accusations, includes disputes over Fukushima nuclear wastewater, the validity of the 1951 San Francisco Peace Treaty, and Japan’s defense policies. These issues have been framed as part of a broader narrative of “new militarism,” according to Chinese state media and officials.

Why is China Intensifying Its Criticism of Japan?

The escalation follows remarks by Japanese Prime Minister Sanae Takaichi in November 2023, in which she addressed Taiwan’s security, prompting a sharp response from Chinese authorities. Chinese critics have since expanded their focus, linking Japan’s actions to historical and legal controversies. For instance, the 2024 transit of a Japan Maritime Self-Defense Force (JMSDF) vessel through the Taiwan Strait coincided with the 129th anniversary of the Treaty of Shimonoseki (1895), a move Chinese state media highlighted as symbolic of Japan’s “militaristic intentions.”

“China’s strategy involves weaving historical grievances with current geopolitical tensions to undermine Japan’s regional standing,” said Dr. Emily Weinstein, a Japan specialist at the Australian National University. “This approach aims to rally domestic support while pressuring Japan diplomatically.”

What Concrete Measures Has China Taken Against Japan?

China has implemented punitive measures, including restrictions on seafood imports from Japan and curbs on rare earth exports. These actions align with broader trade pressures aimed at influencing Japanese policy. Additionally, Beijing has invoked security provisions to justify travel restrictions for Japanese citizens, according to a 2024 report by the Japan External Trade Organization (JETRO).

The Chinese government has also linked its criticisms to its broader Pacific strategy. By questioning the validity of the San Francisco Peace Treaty, which ended World War II, Beijing seeks to challenge Japan’s postwar legal framework. This narrative resonates with China’s goal of unifying Taiwan with the mainland, as it frames Japan’s security policies as a threat to regional stability.

How Is Japan Responding to China’s Campaign?

Japan has adopted a measured approach, avoiding direct confrontation to prevent further escalation. In November 2023, the Chinese Embassy in Tokyo referenced the UN Charter’s “enemy state clause” to warn against Japanese “aggression,” a claim Japan swiftly rebutted. The Japanese Ministry of Foreign Affairs (MOFA) pointed to a 1995 UN General Assembly resolution that deemed the clause obsolete, noting China’s own historical vote in favor of the measure.

“Japan’s response has been calculated to avoid feeding the conflict, but it has yet to develop a comprehensive strategy to counter China’s narrative,” said Hiroshi Nishida, a former Japanese diplomat. “The challenge lies in balancing sovereignty with the need to maintain diplomatic ties.”

What Role Does Domestic Debate in Japan Play?

Chinese media has amplified anti-government protests in Japan, including rallies against constitutional amendments, to highlight divisions within Japanese society. State-run outlets like CCTV have translated coverage of these events into Japanese, aiming to influence public opinion. This strategy reflects Beijing’s effort to exploit internal Japanese debates over security and historical memory.

“The goal is to create a perception of Japan as a fractured state, vulnerable to external pressures,” said Kenji Fujimoto, a political analyst at the Tokyo Foundation. “However, Japan’s democratic institutions remain resilient, and such efforts have limited impact.”

What Are the Broader Implications for Regional Stability?

The tension between China and Japan underscores broader geopolitical shifts in the Western Pacific. China’s military expansion beyond the First Island Chain, including increased patrols near Taiwan, has heightened fears of conflict. Meanwhile, Japan’s security reforms, influenced by U.S. strategic shifts, are viewed by Beijing as a direct challenge to its regional dominance.

“The situation risks becoming a proxy battle for U.S.-China rivalry,” said Laura Rosenberger, a senior
