A Mongabay and CNN investigation found the eight Chinese state-owned ships that conduct deep-sea mining research in China’s mining areas allocated by the International Seabed Authority (ISA) actually spent little time in these exploration areas, while spending much of their remaining time operating in militarily strategic waters. Many of these vessels are linked to the Chinese Navy, have regularly called on military-connected ports, encroached on other countries’ coastal exclusive economic zones and turned off their AIS location beacons. While none of this proves the vessels serve military roles, it suggests the ships may serve dual-use purposes, having a strategic military role as well as a scientific one. With China positioning itself as a leader in deep-sea mining, the U.S. is accelerating its own push to access seabed areas and counter China’s dominance in critical mineral supply chains. The Cook Islands is one hotspot where U.S-China competition is intensifying. As competition heightens between China and the U.S., critics of the industry warn deep-sea mining could cause irreversible harm to marine ecosystems, raising fears that the environment could be the main casualty in this geopolitical rivalry.

In June 2025, the Xiang Yang Hong 01, a chalky white vessel loaded with oceanographic equipment, cruised the Northwest Pacific until it reached a section of the seafloor rich in polymetallic nodules — potato-shaped rocks that contain valuable metals such as manganese,…This article was originally published on Mongabay
