China Imposes Export Controls on Japanese Defense Firms
China has implemented new export controls targeting approximately 20 Japanese defense firms, including Mitsubishi Heavy Industries. The action is seen as retaliation for Japan's remilitarization efforts and recent nuclear policy shifts, adding the companies to control and watch lists amid broader concerns over dual-use technology.
On February 24, 2026, China's Ministry of Commerce announced the new export controls, placing 20 Japanese firms on a blacklist and another 20 on a "watch list". This action prohibits the export of dual-use items—goods and technologies with both civilian and military applications—to the blacklisted companies, which include major defense contractors like Mitsubishi Heavy Industries, Kawasaki Heavy Industries, and IHI Corporation. The move is rooted in China's comprehensive Export Control Law, which came into effect on December 1, 2020, and was further detailed in regulations on dual-use items effective December 1, 2024. These regulations provide a broad framework for restricting exports to safeguard national security and fulfill international non-proliferation commitments. The controlled items can range from critical minerals like rare earths to high-precision sensors and aerospace components. Beijing has explicitly linked the controls to Japan's recent policy shifts, including plans to increase its defense budget significantly, ease long-standing restrictions on arms exports, and develop new long-range missile capabilities. Mitsubishi Heavy Industries, for instance, is under contract to develop new standoff precision missiles for the Japanese Ministry of Defense. The action also follows Japan's updated energy plan, which marks a significant pivot back toward nuclear power. The new policy aims to "maximize" nuclear energy's role, in part to meet the rising electricity demand from digital technologies like AI, and includes the development of next-generation reactors. China's Commerce Ministry cited concerns over Japan's potential nuclear ambitions as a reason for the export controls. The entities on the "watch list," which includes companies like Subaru and TDK Corporation, will face stricter end-user and end-use reviews for their purchases of Chinese dual-use goods. This two-tiered approach allows Beijing to apply pressure not only on direct defense manufacturers but also on the broader industrial and technology base that supports Japan's military modernization. The controls represent a significant use of China's economic leverage to counter what it perceives as threatening strategic developments. This action directly impacts the supply chains for Japan's defense, aerospace, and high-tech manufacturing sectors, which rely on specialized materials and components from China. The market reacted immediately, with share prices of targeted companies like Mitsubishi Heavy Industries, IHI, and NEC falling after the announcement.
