China’s Rare-Earth Card Looms Over Trump-Xi Summit

Why It Matters

U.S. defense readiness and high‑tech manufacturing hinge on rare‑earth supplies, so any Chinese disruption could jeopardize national security and global competitiveness.

Key Takeaways

• China processes 85% of global rare earths, 90% of magnets.
• U.S. Project Vault invests billions but still relies on Chinese supply.
• USA Rare Earth aims to secure Brazil's Serra Verde heavy rare earths.
• Japan’s 15‑year diversification still leaves it 60% dependent on China.

Pulse Analysis

Rare earths—17 metallic elements essential for everything from smartphones to fighter‑jet engines—have become a strategic linchpin in the U.S.-China rivalry. China’s near‑monopoly on processing (about 85% worldwide) and its dominance in heavy‑rare‑earth magnet production give Beijing a powerful lever in trade negotiations. The scarcity is not geological but logistical; extracting and refining these elements at scale requires sophisticated infrastructure that China has built over decades, allowing it to set prices and impose export controls with minimal pushback.

Washington’s response has been aggressive but uneven. Project Vault, a multibillion‑dollar stockpiling and investment program, seeks to create a domestic critical‑minerals reserve while funding overseas mining projects. The recent move by USA Rare Earth to acquire Brazil’s Serra Verde—a rare source of heavy rare earths and a processing plant—marks the most significant non‑Chinese supply foothold to date, though the deal faces antitrust scrutiny. Even with these initiatives, analysts note that the U.S. supply chain will remain dependent on Chinese imports for years, mirroring Japan’s 15‑year effort that still leaves Tokyo over 60% reliant on Beijing.

The timing of the Trump‑Xi summit amplifies the stakes. Chinese officials are likely to wield rare‑earth export restrictions as a bargaining chip, especially as the U.S. ramps up defense spending amid global tensions. For American policymakers, the challenge is twofold: mitigate immediate supply risks while accelerating long‑term diversification. Failure to do so could see rare‑earth scarcity become a recurring flashpoint in future trade talks, reshaping the geopolitical calculus of technology and defense industries alike.
