China adds 40 Japanese entities to export controls in Taiwan dispute escalation

Beijing expanded trade restrictions to 40 Japanese entities Monday, escalating a dispute triggered by Tokyo's Taiwan stance and military buildup.

China barred Chinese companies from selling dual-use goods to 20 Japanese defense contractors and research institutes Monday while placing another 20 firms under enhanced scrutiny, intensifying economic pressure over Tokyo's military expansion and Taiwan policy.

"China's measures are entirely justified, reasonable and lawful. They are aimed at firmly deterring Japan's reckless pursuit of 'new militarism,'" the Commerce Ministry said in a statement, accusing Tokyo of continuing down the wrong path after Beijing's February warnings.

The restricted list includes units of Mitsubishi Heavy Industries, which builds warships and defense systems, Nikko Tokki, a parts supplier to Japan's Self-Defense Forces and coast guard, and the National Institute for Defense Studies. A Komatsu subsidiary was also added. The watchlist covers Mitsui E&S, which makes ship engines, divisions of Fujitsu Corp., and companies in drones and nuclear fuel. Dual-use items affected span rare earths used in motors and magnets, machine tools, batteries and chip-making equipment.

The escalation threatens supply chains across Japan's defense, machinery and rare earth-dependent sectors. Beijing already squeezed heavy rare earth shipments to Japan after Prime Minister Sanae Takaichi said in November that Japan could be drawn into any conflict over Taiwan, a self-ruled island China claims as its own. Japan is set to revise its defense and security documents by December, potentially increasing its defense budget further.

The February round targeted IHI Corp. and NEC Corp., among 20 Japanese firms, and was followed by Beijing throttling flights to Japan and advising Chinese tourists to stay away. Last week, China said it detained two Japanese nationals without disclosing the reason. Japan responded Monday by deploying a Type-12 missile launcher on Minamitorishima, its southernmost island, an apparent counter to China's expanding presence in the Pacific.

Rare Earths and Supply Chain Leverage

China controls about 60% of global rare earth mining and an even larger share of processing, giving it significant leverage over Japanese manufacturers. The dual-use restrictions cover rare earths essential for electric vehicle motors, defense systems and advanced electronics, as well as machine tools, batteries and semiconductor production equipment. The previous round in February already squeezed heavy rare earth exports to Japan, and the latest expansion broadens the scope to include more industrial and defense-related components.

Market Implications and Forward Outlook

For investors, the key risk is sustained supply chain disruption. Japanese defense contractors including Mitsubishi Heavy Industries, IHI and NEC face potential shortages of dual-use goods from China. Rare earth prices could see upward pressure if Beijing tightens controls further. The UK, Germany and France last week issued a rare joint statement condemning Chinese activities in waters east of Taiwan, adding a multilateral dimension to the standoff. Japan's defense document revision due by December will be a key catalyst to watch — any further increase in defense spending could trigger additional Chinese retaliatory measures.
