China presses Japan on rare earths, a repeat of the 2010 showdown

China has blocked Japan from obtaining several rare earths, heavy materials, and other minerals for at least four months. This coincides with a dispute over Taiwan between the two nations, indicating that Beijing is using its control of critical minerals to gain diplomatic leverage.

Japan is the second largest producer of rare-earth magnets outside of China, but, like the rest of the globe, it is largely dependent on Beijing to import certain heavy rare earths, which are used in magnets, aerospace, and defence as well as gallium.

Chinese customs data show that since December, Chinese exports to Japan of rare earth minerals such as dysprosium and terbium oxide, along with speciality metals gallium, have all but stopped, except for a small number of shipments of the yttrium.

Major Japanese magnet maker Shin-Etsu ?has stopped accepting new orders for dysprosium-containing magnets, according to a Western customer who spoke on condition of anonymity. The company declined comment.

The halt in exports began soon after a diplomatic row erupted over Taiwan in November. It is similar to Beijing's throttling exports of such materials to the U.S., during the current trade conflict.

Beijing tightened its export controls in Japan twice, firstly, in January and then again, the month after, targeting conglomerates such as?the shipbuilding division and aero engine division of Mitsubishi Heavy Industries.

Ryosei Acazawa is scheduled to attend a meeting on Saturday. He is the highest-ranking Japanese official to have visited China since the dispute began.

Tokyo takes measures to release stockpiled supplies when necessary, but does not reveal details. An official from the Japanese Industry Ministry said that the government was aware of the concerns about rising prices and tightening supply.

RARE EARTH DÉJA VU

David Merriman said that Japanese companies were better protected from the pressure campaign because a similar drop in Chinese rare earth mineral exports?in 2010 led to the building of stocks. The Japanese have also tried to reduce the use of heavy rare Earths in magnets, and looked for alternatives.

According to data, China continues to export normal quantities (of the rare earth magnets) used by the automotive and other industrial industries.

Components maker TDK said it does not expect any major impacts and has been diversifying its sources of supply. Mitsubishi Motors announced in February that it has secured rare earths until mid-year.

Japan has funded alternative producers, such as Lynas rare earths in Australia. Last year it became the first commercial producer outside China of separated terbium-dysprosium. The company has also launched rare-earth projects in Australia, France, and Australia.

It will take years for the Chinese to replace their supply of heavy rare earths. Lynas will produce 8 metric tonnes of dysprosium in the first quarter 2026. In 2024, China exported 14 tons of these two minerals per month to Japan.
