Opinion | China Imposes Export Controls on Japanese Businesses, Bilateral Tensions Rise

The diplomatic rupture took center stage in February when Chinese Foreign Minister Wang Yi (王毅) publicly condemned Japanese Prime Minister Sanae Takaichi's security posture.Speaking in Munich, Wang accused Takaichi of undermining Chinese territorial sovereignty and warned that Japan's military expansion would carry severe consequences.In a remarkably blunt historical critique, Wang contrasted Japan's approach to its wartime past with Germany's post-World War II reckoning, questioning whether Tokyo remains under the shadow of militarism.The hardline declaration signaled that Beijing's frustration had moved beyond standard diplomatic grievances.

Days later, on Feb.24, China's Ministry of Commerce turned that rhetoric into policy.Invoking the country's Export Control Law, the ministry added 20 Japanese defense-related companies and institutions — including subsidiaries of Mitsubishi Heavy Industries, Kawasaki Heavy Industries, and IHI Corp. — to a strict export control list.The designation imposes an immediate ban on the export of dual-use goods, which have both civilian and military applications, to the targeted entities.

Simultaneously, Beijing placed another 20 Japanese firms, including automaker Subaru, on a secondary watch list. While not subject to an outright ban, companies on this list face intense administrative hurdles.Future exports to these firms will require stringent licensing reviews, comprehensive risk assessments, and strict end-use verification.

The dual-list system functions not as a one-time punitive measure, but as a flexible policy tool designed to exert sustained pressure. By shifting export activities from open market transactions to administrative licensing, Beijing has introduced significant institutional volatility into global supply chains.According toThe Wall Street Journal, the restricted dual-use products include rare earth elements, heavy rare earth magnets, mechanical equipment, and semiconductor manufacturing materials. Licensing reviews for certain rare earth products have already been suspended, threatening to disrupt both defense and broader commercial manufacturing.

Capital markets quickly reacted to the shifting risk landscape. Shares of Mitsubishi Heavy Industries fell 3.6%, IHI dropped 6.2%, and Kawasaki Heavy Industries declined by approximately 5%. Subaru also saw its stock dip after being named to the watch list. The market sell-off underscores investor anxiety that these export controls represent a structural policy shift rather than an isolated corporate dispute.

These economic restrictions are unfolding against a backdrop of heightened military posturing.Over the past year, China has markedly increased its military footprint in the Western Pacific and the East China Sea. Operations involving aircraft carrier strike groups and frequent joint naval and air exercises have become routine. As reported by theFinancial Times, China's military deployments are transitioning from temporary demonstrative exercises to a normalized, long-term strategic presence.

Consequently, Japan is being forced to adjust its own defense deployments and strategic planning. The integration of economic coercion into this security framework elevates the overall risk rating for the region, translating geopolitical friction into tangible pressures felt directly by industrial sectors and capital markets.

Historically, Sino-Japanese relations were defined by "cold politics, hot economics," a paradigm where robust trade flourished despite political friction.However, as Beijing increasingly subjects critical minerals and dual-use technologies to institutional regulation, the economic sphere is no longer a safe buffer zone. It has become a primary theater for security competition.

From the diplomatic rebukes in Munich to the calculated rollout of export blacklists, interactions between Beijing and Tokyo have evolved into an era of institutionalized competition. While these measures may not trigger an immediate military crisis, the synchronized advancement of military normalization and economic instrumentalization ensures that Japan will face sustained, long-term pressure on both its security planning and its industrial supply chains.
