TOKYO: Japan is set to deepen cooperation with the United States on the development of deep-sea rare earth resources, as both nations move to secure critical mineral supplies and reduce dependence on China.
Prime Minister Sanae Takaichi announced on Wednesday that the issue would be a key topic during her upcoming meeting with US President Donald Trump.
The discussions will focus on jointly exploring and developing rare earth deposits located near Japan’s remote Pacific territory of Minamitorishima, according to AFP.
The move follows a successful Japanese test mission last month, during which sediment rich in rare earth elements was retrieved from depths of approximately 6,000 meters.
The operation was carried out by the deep-sea drilling vessel Chikyu, which began its expedition in January to assess mineral potential in the region.
Rare earth elements—a group of 17 metals—are essential components in a wide range of modern technologies, including electric vehicles, advanced electronics, and defense systems.
Their strategic importance has intensified global competition, particularly as China continues to dominate supply chains.
Takaichi told parliament that preliminary discussions between Japan and the United States began earlier this year, building on earlier talks held during President Trump’s visit to Japan in October.
She expressed expectations that concrete plans for collaboration would be outlined during the summit scheduled for Thursday. The initiative comes at a time of heightened tensions between Tokyo and Beijing.
Relations have been strained since Takaichi indicated last year that Japan could respond militarily in the event of a Taiwan conflict—an issue China considers highly sensitive.
In response, China has imposed restrictions on exports of certain dual-use materials to Japan, raising concerns about potential disruptions to critical supply chains, including rare earth minerals.
China has historically leveraged its dominance in rare earth production as a geopolitical tool, particularly during periods of trade friction with the United States and its allies.
Amid these concerns, Washington has also taken steps to strengthen international cooperation.
Last month, the United States launched a new critical minerals partnership involving the European Union and Japan, aimed at securing alternative sources and stabilizing supply chains.
Japan’s push to develop domestic and offshore rare earth resources, in collaboration with trusted allies, signals a broader effort to enhance economic security and technological independence in an increasingly competitive global landscape.
