| Deep-sea rare earth mining |
The United States and Japan plan the world's deepest undersea mining project at Minamitorishima to challenge China's dominance in critical minerals. President Donald Trump and Japanese Prime Minister Sanae Takaichi advanced this strategic initiative during their March summit. Consequently, both nations aim to establish a secure, closed-loop rare earths supply chain that bypasses Chinese export controls.
Japan's Cabinet Office recently released positive results from test samples retrieved near the remote Pacific island. Furthermore, Houston-based Deep Reach Technology has held preliminary discussions with Japanese officials regarding extraction methods. However, formidable engineering challenges remain because the deposits lie approximately six kilometers beneath the ocean surface under extreme water pressure.
Beijing views these developments with growing concern, deploying research vessels and an aircraft carrier near the exclusive economic zone. In response, Tokyo has reinforced the island's defenses with missile launchers and radar systems to safeguard future operations. Therefore, this ambitious undersea venture serves as both an economic necessity and a crucial geopolitical deterrent against Chinese resource leverage.

This ambitious deep-sea project highlights the aggressive push by Washington and Tokyo to decouple from Chinese rare earth dependencies despite severe technical hurdles.
Sustained capital allocation and technological breakthroughs in ultra-deepwater extraction will dictate whether commercial-scale production becomes viable by the next decade.
