China Mapping Ocean Floor for Submarine Warfare, Reuters Finds
Eight Chinese state-owned research vessels spent only 6% of their time in designated deep-sea mining areas over five years (January 2021-January 2026), instead conducting extensive seafloor mapping in militarily strategic waters near Guam, Taiwan, the Bering Sea, and undersea cables. The vessels, equipped with powerful bathymetric sensors, traveled 102,000 kilometers in exploration zones and repeatedly operated near U.S. military installations, submarine routes, and critical undersea infrastructure.
Why it matters
China's covert ocean floor mapping near military chokepoints and undersea cables could give its navy decisive advantages in submarine warfare and allow it to target the fiber-optic infrastructure carrying global internet and financial traffic. Meanwhile, the rush toward deep-sea mining to fuel this competition threatens permanent damage to fragile marine ecosystems that we're only beginning to understand.

Where do you stand?
Should wealthy nations prioritize preventing deep-sea mining to protect fragile ocean ecosystems, even if it means ceding rare earth mineral resources and strategic advantage to competitors?
How much surveillance and intelligence operations should democracies conduct in international waters to counter perceived military threats from rival powers?
Should undersea cable networks be treated as critical national infrastructure deserving military protection, similar to how nations defend power grids?
