China bars dual-use exports to Japan citing military end-use

China's Ministry of Foreign Affairs said Sept. 21 that Beijing's export controls on dual-use materials explicitly aim to prevent Japanese military end-use and halt regional remilitarization efforts.

Spokesperson Guo Jiakun reaffirmed the policy during a regular press briefing in Beijing. The statement came two days before President Xi Jinping travels to the United States on Sept. 23.

The export controls affect 80 Japanese companies across defense, automotive and heavy machinery sectors. China's Ministry of Commerce divides these targets between an outright ban list and a restricted review list.

The restrictions have already halted strategic mineral flows to Japanese industry. Chinese yttrium exports to Japan dropped from roughly 30 metric tons monthly before the curbs to zero in June 2026.

Yttrium serves as a vital stabilizer in thermal barrier coatings for jet engines and gas turbines. Japan relies on China for more than 90% of its processed heavy rare-earth compounds.

Beijing anchored the current restrictions in Announcement No. 1, issued by the Ministry of Commerce on Jan. 6, 2026. The decree took effect immediately without a transitional grace period.

Announcement No. 1 bans all dual-use items destined for Japanese military users. It also prohibits sales for military end-uses or any civilian applications that enhance Japanese defense capabilities.

The regulation draws authority from the 2020 Export Control Law. It also operates under the State Council Regulations on the Export Control of Dual-Use Items, which took effect Dec. 1, 2024.

The commerce ministry expanded specific enforcement actions on Feb. 24, 2026 through Announcements No. 11 and No. 12. That wave added 20 Japanese entities to the Export Control List.

Shipbuilding unit Mitsubishi Heavy Industries Shipbuilding was among the first group placed on the Export Control List. Inclusion imposes an immediate and total embargo on Chinese-origin dual-use components and materials.

The ministry placed another 20 Japanese companies on a secondary Watch List that same day. Automotive manufacturer Subaru Corporation appeared on the Watch List, triggering enhanced regulatory scrutiny.

Watch List status strips companies of general export licensing privileges. Exporters must submit dedicated risk assessment reports and written pledges guaranteeing products will not support military expansion.

Article 17 of the dual-use regulations normally sets statutory deadlines for licensing reviews. The commerce ministry suspended those deadlines for Watch List entities, allowing regulators to hold applications indefinitely.

The ministry released a second enforcement wave on June 29, 2026 through Announcements No. 27 and No. 28. Regulators added another 40 Japanese organizations across both lists.

The June 29 update placed the National Institute for Defense Studies on the Export Control List. The defense and space technology units of Mitsubishi Electric were also added to the ban.

Maritime machinery builder Mitsui E&S was placed on the Watch List in the same decree. The action subjected the company to single-transaction licensing reviews with no statutory decision deadlines.

The commerce ministry added reporting requirements on June 24, 2026 under Announcement No. 26. The rule established a whistleblowing framework for suspected violations involving strategic minerals, taking effect July 1.

The export rules enforce broad extraterritorial jurisdiction over global supply chains. Overseas companies cannot transfer or re-export Chinese-origin dual-use goods to listed Japanese entities from third countries.

That extraterritorial reach exposes manufacturing intermediaries in South Korea and Taiwan. Regional assemblers using Chinese subcomponents must trace every downstream shipment bound for Japanese industrial conglomerates.

Third-country exporters face severe legal liability under Chinese trade law for unauthorized diversions. Violations can trigger administrative fines, criminal referral or inclusion on Beijing's corporate countermeasure rosters.

Beyond heavy rare earths, the controls cover critical inputs including tungsten, molybdenum and gallium. High-performance carbon fiber and advanced telemetry sensors also fall under the dual-use restrictions.

Japanese manufacturers have coped by drawing down domestic mineral reserves built over prior quarters. Industrial groups have also attempted to qualify alternative refining sources in North America and Australia.

Heavy rare-earth separation capacity outside China remains constrained. Industrial analysts estimate alternative processing lines will require at least two years to replace Chinese supply volumes.

The commerce ministry has not published the specific tariff codes covered by Announcement No. 1. Regulators also have not clarified whether civilian subsidiaries of listed conglomerates face automatic license rejections.

President Xi travels to the United States on Sept. 23, 2026 for high-level diplomatic meetings. The trade measures remain in full force with no scheduled expiration date.
