How the China–Japan Rift Could Inflict Economic Pain on Both Countries

China and Japan are embroiled in a diplomatic dispute that threatens significant economic consequences for both nations. The confrontation intensified after Japanese Prime Minister Sanae Takaichi suggested on Nov. 7 that an attack on Taiwan could constitute an existential threat to Japan and potentially justify a forceful response. Beijing condemned the remarks, saying they damaged trade cooperation, and has responded with a range of economic and diplomatic measures.

Recent Developments

Beijing sent a letter to the United Nations warning it would act in self-defense should Japan “intervene militarily in the Taiwan Strait.” The Chinese embassy in Tokyo posted on X (formerly Twitter) that China reserves the “right to take direct military action” without U.N. Security Council authorization if Japan renews an “aggressive” policy. Takaichi has declined to retract her comments, saying they reflect Japan’s long-standing positions, while Tokyo has sought to calm tensions through behind-the-scenes diplomacy.

Economic Measures and Cultural Fallout

Analysts say Beijing has used a mix of targeted measures that include reinstating limits on some Japanese seafood imports, advising Chinese citizens against travel to Japan, and allowing cancellations or postponements of cultural events and film releases. Several Japanese concerts and movie premieres in mainland China reportedly were postponed, while some airlines and carriers offered flexible cancellations for trips to Japan. Market researchers estimate roughly 30% of planned trips from China to Japan through December have been canceled—potentially costing Japan between $500 million and $1.2 billion in lost tourism revenue.

Business and Supply-Chain Risks

Major Japanese firms with Chinese operations—such as automakers and electronics companies—express concern about potential blowback that could affect factories and supply chains. Subramania Bhatt, CEO of China Trading Desk, describes the current measures as “sharp pinpricks” rather than a knockout blow, but warns that continued escalation could pose wider commercial risks.

Political and Social Dynamics in Japan

Public reaction in Japan has been mixed. While some communities and local businesses lament the loss of high-spending Chinese tourists, others—particularly in over-touristed neighborhoods—express relief. Polling since Takaichi took office shows a rise in her approval ratings and increased public support for collective self-defense in the event of an attack on Taiwan, illustrating how the dispute may bolster her domestic political standing even as it raises economic costs.

China’s Leverage and Limits

Observers note Beijing retains several levers—curbing investment, launching trade investigations, or restricting exports—but also faces constraints. China controls much of the rare-earths processing chain, a strategic advantage that could be used as leverage. Yet experts caution that an outright embargo on rare earths would invite global scrutiny and could accelerate international efforts to diversify supplies, undercutting China’s long-term leverage.

Longer-Term Implications

Many analysts expect the dispute to accelerate Japan’s efforts to “de-risk” its economic dependence on China: subsidizing supply-chain relocation, tightening export controls on advanced technologies, and seeking alternative partners for critical materials. Scholars warn that a protracted standoff would push relations further from the old pattern of “cold politics, hot economics” toward “cold politics, cooler economics,” potentially driving Japan closer to U.S.-led economic and security groupings.

Outlook

So far, Tokyo has limited its response to diplomatic protests and quiet negotiation. Both sides appear to be testing each other’s red lines. The dispute contains risks for both economies—immediate tourism and cultural losses for Japan and potential reputational and trade costs for China—while raising the prospect that economic friction could have enduring strategic consequences for regional supply chains and alliances.
