Highlights

• China controls 90% of global rare earth refining capacity and implements new regulatory measures to further control global supply.
• New regulations expand quota systems to imported raw materials, closing previous loopholes in rare earth processing.
• Western nations are accelerating investments in alternative rare earth supply chains to reduce dependence on Chinese resources.

China has once again signaled to the world that it will not loosen its grip on rare earth elements and magnets. On August 22, Beijing’s Ministry of Industry and Information Technology (MIIT) announced new interim measures that place tighter oversight on mining, smelting, and separation of rare earths—including imported raw materials. The move underscores both China’s enduring dominance and its willingness to leverage regulatory tools as geopolitical assets.

What’s Changing—and Why It Matters

The new measures expand the quota system to cover not just domestically mined ores, but also imported feedstock refined inside China. Companies must now secure government approvals, report production accurately, and risk penalties—including quota cuts—for violations. The framework spans 407 product categories, touching everything from magnets for EVs and turbines to compressors and defense-grade alloys.

Crucially, Beijing withheld specific production and export quota numbers, preserving ambiguity as a strategic lever. Analysts note that this silence allows China to fine-tune restrictions based on trade tensions, industrial priorities, or diplomatic needs.

Facts Anchored in Market Reality

No exaggeration is needed: China controls about 90% of global rare earth refining capacity, mines around 70% of the supply, and holds nearly half of the known reserves. The U.S. sourced 70% of its rare earth imports from China in 2024, while the EU’s dependence runs even higher. These are structural vulnerabilities, not hypotheticals.

Between the Lines: Control or Chokehold?

Western headlines have veered toward alarm, with talk of looming collapses in American EV and defense supply chains. That framing overstates the immediate risk. This clampdown is less a sudden chokehold than a codification of long-running control. China has tightened and loosened quotas in the past without causing systemic breakdowns. What’s different now is the formal inclusion of imported ore—closing loopholes that previously gave non-Chinese miners indirect access to Chinese refiners.

The timing also matters. The new measures follow Beijing’s April decision to add several rare earth oxides and magnets to its export restriction list—retaliation against U.S. tariff hikes. It is clear that China is using rare earths not just as an industrial policy but as geopolitical ballast.

The Global Response

If China’s intent was to remind markets of its power, the message landed. Western governments and investors are already pouring capital into diversification plays:

• Australia: Iluka Resources is advancing its A$1.65 billion Eneabba refinery project.
• North America: MP Materials and Energy Fuels are scaling domestic separation capacity.
• Africa: Projects like Longonjo (Angola), Ngualla(Tanzania), and Songwe Hill (Malawi) are seeing renewed U.S., European, and Japanese interest.

Each twist in Beijing’s regulatory regime strengthens the investment case for these ex-China supply chains. But time is of the essence and a comprehensive integrated industrial policy still lacks in the West.

Pollution, Power, and Politics

Environmental language within the new measures should not be overlooked. Tighter rules on radioactive waste and residues in processing may be intended to bolster Beijing’s international credibility. Yet history suggests such measures are selectively enforced—particularly when export leverage is at stake.

For global buyers, the core truth remains: the “open” market for rare earths is illusory when one country dictates refining volumes, sets opaque quotas, and ties supply to political bargaining.

Investor Takeaway

This is evolution, not revolution. China’s clampdown is real but incremental, aimed at consolidating control rather than triggering immediate shortages. The real impact will be longer-term: accelerating Western diversification, hardening supply chain nationalism, and raising the floor for investment in projects outside China’s orbit.

For investors tracking the sector, the writing on the wall is clear—Beijing will continue to use rare earths as both shield and sword. Those positioned in emerging ex-China projects may find that every turn of the screw in Beijing only sharpens their opportunity.
