UPDATE 3-China imposes export controls on 20 Japanese entities to curb ‘remilitarisation’

China has prohibited the export of dual-use items ‌to ​20 Japanese entities that it says supply Japan's military, the commerce ministry announced on Tuesday, in the latest escalation of a dispute with Tokyo.

China is using its influence over supply chains to ratchet up pressure on Tokyo ‌even after Prime Minister Sanae Takaichi, who angered Beijing with comments about Taiwan in November, won a sweeping mandate in a landslide election victory this month. The measures target units of major Japanese industrial conglomerates such as Mitsubishi Heavy Industries' shipbuilding and aero engines divisions, the ministry said.

The rules effectively cut companies off from the ‌seven rare earths and associated materials currently on China's dual-use control list, along with a swathe of other controlled critical minerals. The new rules bar ‌exports of rare earths like dysprosium, yttrium or samarium which play tiny but vital roles in cars, planes, weapons and consumer electronics. It is not clear how long it might take for shortages to become an issue. Japanese companies are well-known for maintaining rare earth stockpiles and until at least December, the latest date for which export data is available, China was regularly sending large shipments ⁠to Japan.

China ​has an export control list of ⁠around 1,100 dual-use items and technologies and manufacturers need to secure a licence to be able to ship them overseas, wherever the end user may be. "The measures announced today are completely unacceptable and ⁠deeply regrettable," Japan's Deputy Chief Cabinet Secretary Kei Sato told a press briefing.

The government in Tokyo has demanded their withdrawal, Sato said. WATCH LIST The restrictions were aimed at curbing Japan's "remilitarisation" ​and nuclear ambitions, China's commerce ministry said, adding overseas organisations and individuals were also banned from transferring Chinese-origin dual-use items to the listed entities.

Firms could ⁠apply to sell to the listed entities under "special circumstances" that required them to export, the ministry said. China has assured that entities operating "in good faith" have no reason to worry, and that the ⁠measures ​announced would not affect normal economic and trade exchanges between the two countries.

The ministry also added another 20 Japanese entities, including Subaru Corp, Itochu Aviation and Mitsubishi Materials Corp to a watch list, saying it could not verify the end-users or end-uses of the entities' dual-use items. Subject to stricter scrutiny, companies exporting ⁠to these entities would have to apply for individual export licences for dual-use items and provide a written commitment that the items would not contribute to enhancing ⁠Japan's military capabilities. None of the affected ⁠Japanese companies contacted by Reuters had an immediate comment on the trade measures. Market reaction in Tokyo was mixed, with Subaru shares falling 3.5% while Mitsubishi Materials shares rose 3.8% and Mitsubishi Heavy shares were down 3.1%.
