Scott Bessent Meets China's He Lifeng as Three Rare-Earth Clocks Converge

Highlights

• Treasury Secretary Bessent and USTR Greer meet Chinese Vice Premier He Lifeng in New York ahead of the September 24 Trump-Xi summit with rare earths on the agenda
• Three converging deadlines—September 24 diplomacy, November 10 tariff truce expiry, and January 1 2027 DFARS NdFeB supply-chain restrictions—are reshaping U.S.-China mineral negotiations
• Washington remains dissatisfied with Chinese rare-earth flows, with yttrium exports demonstrating how shipments can become country-specific leverage
• The DFARS 2027 restrictions cover the entire NdFeB supply chain from mining through finished magnets for defense procurement
• REEx frames the standoff as Great Powers Era 2.0 ecosystem competition where AI, chips, magnets and defense production share the same strategic chessboard

Rare earths are no longer a side issue in U.S.-China trade talks—they are becoming part of the negotiating architecture of great-power competition. Treasury Secretary Scott Bessent (opens in a new tab) and U.S. Trade Representative Jamieson Greer meet Chinese Vice Premier He Lifeng (opens in a new tab) in New York ahead of the September 24 Trump-Xi summit, with rare earths, critical minerals, AI and trade on the agenda. Washington says Chinese critical-mineral flows remain below expectations. The backdrop is unusually combustible: September 24 diplomacy, the November 10 trade-truce deadline and the January 1, 2027 DFARS supply-chain restriction are now converging.

REEx Insight — Three Clocks, One Chokepoint

Investors should watch the calendar more closely than the communiqués. Clock One: September 24. China is bringing an unusually large corporate delegation, potentially including executives from BYD, CATL, Xiaomi and others. Yet Washington reportedly rejected a proposed U.S.-China CEO roundtable, while broader business and think-tank engagement appears limited. That combination—more CEOs, fewer forums—suggests tightly controlled transactional diplomacy rather than a broad reopening.

Clock Two: November 10. The tariff truce expires, while Washington remains dissatisfied with Chinese rare-earth and critical-mineral flows. Reuters reports that aerospace and semiconductor users continue struggling for access despite improved shipments. Yttrium demonstrates the danger: exports can resume, tighten again and effectively become company- or country-specific leverage.

Clock Three: January 1, 2027. DFARS restrictions expand across the entire NdFeB supply chain—from mining through finished magnets—for covered-country material used in applicable defense procurement.

That is where diplomacy meets metallurgy.

Great Powers Era 2.0™: The Supply Chain Becomes Statecraft

REEx has argued that Great Powers Era 2.0™ is ecosystem versus ecosystem. AI models, chips, energy, metals, magnets, defense production and capital increasingly sit on the same strategic chessboard. The source material similarly recognizes that AI competition now reaches across chips, minerals and infrastructure.

Iran and Venezuela deepen that backdrop, but causation should not be overstated. U.S. military and geopolitical actions cannot responsibly be reduced to minerals. What can be said is that kinetic conflict, sanctions, energy security and mineral dependence increasingly intersect in Great Powers Era 2.0 as REEx has suggested—and China possesses substantial leverage inside that system (although, as REEx chronicles, the Asian nation faces its own crises) at this point. Perhaps more so than U.S. media suggests. Iran is explicitly on the Trump-Xi agenda, while U.S.-Venezuela relations have moved rapidly toward energy cooperation following Washington’s removal of Maduro.

The critical question from New York to Washington is therefore not whether Beijing ships more magnets next month.

It is whether America can use any negotiated breathing room to build a supply chain that no longer requires Beijing’s permission to function.
