ISTANBUL (AA) - A Japanese research ship began a mission Monday to test the extraction of rare earth minerals from the deep sea, as Japan seeks to reduce its reliance on supplies from China, according to NHK News.
The vessel departed Shimizu Port in central Japan and is heading about 150 kilometers (93 miles) southeast of Minamitorishima Island, within Japan’s exclusive economic zone.
Japanese scientists say the seabed in the area, around 6,000 meters (3.7 miles) below the surface, contains large deposits of rare earth minerals.
These materials are critical for high-tech products, including smartphones, electric vehicles, wind turbines and military equipment.
During the mission, researchers will test newly developed pipes and mining equipment designed to operate under extreme deep-sea conditions.
The testing phase is expected to last about 20 days, with the ship scheduled to return on Feb. 14.
The move follows China’s recent tightening of export controls. Last week, Beijing announced a ban on the export of dual-use items to Japanese end users for military purposes or other uses deemed to strengthen Japan’s military capabilities.
The measures could affect industries including drones, advanced technologies and rare earth materials.
Deep-sea mining remains in its infancy, with no commercial operations yet in place, though the US last year moved to expedite permitting.
Environmental groups warn that deep-sea mining could damage marine ecosystems and spread pollution.
