According to Forbes, China has implemented sweeping new restrictions on rare earth element exports, requiring government licenses for any products containing more than 0.1% Chinese-sourced rare earths or using Chinese rare earth technology. With China controlling approximately 70% of global mining, 92% of refining, and 98% of magnet production, these measures effectively give Beijing veto power over materials essential to advanced weapons systems and consumer technologies. This escalation in the rare earth conflict has prompted significant Western countermeasures, including a $400 million Department of Defense investment in MP Materials and a new U.S.-Australia critical minerals agreement.

The Strategic Importance of Rare Earths
Rare earth elements aren’t actually rare in geological terms—their challenge lies in the complex, environmentally intensive extraction and separation processes required to produce usable materials. The 17 rare earth elements function as technological enablers rather than bulk materials, with even minute quantities dramatically enhancing performance in magnets, catalysts, and phosphors. What makes China’s dominance particularly concerning is that these elements aren’t easily substitutable in high-performance applications—the magnetic properties of neodymium in electric vehicle motors or the thermal stability of samarium in defense systems have no equivalent alternatives that match their performance characteristics.
The Real Challenges in Decoupling Supply Chains
While Western investments in rare earth projects are accelerating, the timeline for meaningful supply chain independence extends far beyond simple capital allocation. The environmental permitting process for new mining operations typically spans 7-10 years in Western democracies, compared to China’s ability to fast-track projects through centralized planning. More critically, the separation and refining expertise represents decades of accumulated knowledge that China has systematically developed while Western nations outsourced production. Building equivalent refining capacity requires not just capital but specialized chemical engineering talent that has largely atrophied outside China.
Market Distortions and Investment Risks
The current rush to fund rare earth projects carries significant risk of creating inefficient market outcomes. Government subsidies and defense-driven investments may prioritize strategic security over economic viability, potentially creating zombie operations that survive only through continued public support. The concentration of investment in early-stage projects also overlooks the mid-stream processing gap—even if Western nations successfully develop mining capacity, they remain dependent on Chinese separation technology and magnet production expertise. This creates a scenario where Western-mined concentrates might still need to be shipped to China for processing before returning as finished products.
A Realistic Path Forward
The most viable strategy for Western nations likely involves targeted investment in specific elements rather than attempting blanket coverage of all 17 rare earths. Focusing on the most critical defense applications—particularly heavy rare earths like dysprosium and terbium used in high-temperature military systems—represents a more achievable near-term goal than complete supply chain independence. Additionally, significant opportunity exists in developing recycling infrastructure for end-of-life products containing rare earths, creating a circular economy that reduces primary extraction requirements. The geopolitical reality suggests we’re entering an era of managed competition rather than complete decoupling, with strategic stockpiling and diversified sourcing providing interim security while domestic capabilities mature.
