Highlights
- Dr. Marina Yue Zhang argues China's rare earth supremacy rests on three interlocking advantages:
- Control over heavy rare-earth resources
- Monopoly on separation technology
- A complete mine-to-magnet industrial ecosystem the West cannot replicate for at least a decade
- China's one-year 'pause' on export controls is tactical power projection, not concession—buying Beijing time while Western supply chains face a 10-15 year buildout timeline that favors incumbent scale and process know-how.
- REEx agrees true Western resilience is 5-10 years away and recommends:
- Focused, subsidized China-free chains for defense and critical applications
- Accelerated recycling and dysprosium/terbium thrifting to compete on unit costs
Dr. Marina Yue Zhang, (opens in a new tab) an academic and author specializing in the intersection of technology, innovation, and geopolitics, argues in The Diplomat (November 8, 2025) that the West remains structurally unable to escape China’s rare-earth dominance—at least for now.
Zhang, a scholar affiliated with the University of Technology Sydney and author of Demystifying China’s Innovation Machine (Oxford University Press, 2022), contends that Beijing’s supremacy is no accident of geology but the product of a forty-year industrial fortress built through patient state investment, environmental tolerance, and technical mastery.
Her central thesis: the West misreads China’s one-year “pause” on rare-earth export controls as concession when it is, in reality, a calculated exercise of power—a tactical slowdown that buys Beijing time while reinforcing its three enduring advantages: control over heavy rare-earth resources, a monopoly on separation technology, and a complete mine-to-magnet industrial ecosystem that the United States and Europe are still at least a decade away from replicating.

Three Locks, One Fortress
Zhang’s core thesis: China’s lead isn’t geology; it’s an industrial fortress built over 40 years. She argues three mutually reinforcing “locks” keep the West dependent:
- Resource Lock: Economic access to heavy rare earths (Dy/Tb) via ion-adsorption clays (and Myanmar flows) beats Western hard-rock costs.
- Technology Lock: Decades of solvent-extraction know-how, process IP, and talent now restricted for export—hard to copy, slower to qualify.
- Ecosystem Lock: A complete mine-to-magnet-to-markets chain—and the world’s biggest domestic demand—creates scale the West can’t match quickly.
The “Pause” That Wasn’t a Retreat
Zhang reads the Busan “pause” on export escalation as tactical, not capitulation: Stage-1 licensing stays in place; Stage-2 threats were merely holstered to win tariff relief. Her argument: time asymmetry. Mine-to-magnet buildouts take 10–15 years; China’s “grubby” chokepoints endure longer than high-tech export controls.
Where REEx Agrees—and Pushes Further
REEx has been on record: true resilience is 5–10 years away—and only with sustained policy, CapEx, and customer offtakes. See: Roadmap to Western Rare Earth Independence—with the Meter Running (RareEarthExchanges.com). Our supply-chain view aligns with Zhang’s locks, especially around HREE bottlenecks and process know-how.
What’s Solid, What’s Speculative
Well-supported: China’s dominance in HREE supply, export-control leverage, scale economics, and the multi-year runway Western projects require.
Speculative edges: Precise shares for Myanmar inputs can swing; the implied inevitability of Western cost gaps ignores recycling gains, thrifting (GBD), and policy-backed offtakes now accelerating in North America.
Investor Lens: Compete Narrowly, Not Everywhere
Zhang urges targeted, China-free chains for defense and grid—permanently subsidized if needed. REEx concurs: focus on assured access (not autarky), ruthless unit-cost clarity, and rapid qualification for Dy/Tb-bearing products. The scoreboard today still favors China—but U.S. policy velocity and market activity are finally moving metal, not just memos.
Summary
This piece distills Marina Yue Zhang’s Diplomat argument—China’s rare earth dominance endures via resource, technology, and ecosystem “locks”—and juxtaposes it with REEx’s stance that Western resilience is 5–10 years away. We flag what’s fact-based vs. speculative, and translate it into investable takeaways: build narrow, subsidized, assured-access chains for critical uses while scaling recycling and Dy/Tb thrifting.

A compelling analysis. What stands out most is the reminder that rare earth dominance is not simply a matter of resources, but of accumulated industrial capability the “fortress” China has spent four decades building. The Busan pause makes far more sense when seen through that lens. Not concession, but strategic patience while Beijing manages its own vulnerabilities. For countries in the Indo-Pacific and in resource-rich regions such Africa, this reinforces the urgency of building selective, resilient supply chains rather than chasing full duplication. The challenge is to identify where targeted cooperation, long-term investment and shared standards can meaningfully reduce exposure to single points of failure. This is a long game and Zhang captures that reality with real clarity.
