- China imposes export restrictions on critical rare earth elements in response to US tariffs.
- Rare earths are vital for military and high-tech applications, with China controlling 90% of global supply.
- The Biden administration views dependency on Chinese rare earths as a national security risk.
Escalating Trade Measures
China has tightened its grip on rare earth exports, restricting seven categories of medium and heavy rare earth elements—including samarium, gadolinium, and dysprosium—as retaliation against heightened US tariffs. The move comes after President Trump increased tariffs on Chinese imports to 54%, later expanding them to 125% amid ongoing trade tensions.
"This is a calculated response," said one industry analyst familiar with the matter, speaking on condition of anonymity. "China knows where it hurts."
Strategic Vulnerability
Rare earth elements are indispensable for jet engines, missile guidance systems, and advanced computing—key components of US defense infrastructure. With China producing 90% of the global supply, Washington faces mounting pressure to secure alternative sources.
The Biden administration has flagged the dependency as a national security concern, particularly as Beijing continues leveraging its supply chain dominance. "We're playing catch-up," a Defense Department official admitted, noting that foreign producers have engaged in price manipulation and arbitrary export controls.
Market Reactions
While specific details about "unfreezing" rare earth discussions remain undisclosed, industry sources suggest behind-the-scenes negotiations are ongoing. The Trump administration has launched investigations into critical mineral imports, aiming to reduce reliance on adversarial nations.
One European trader, who requested anonymity due to market sensitivities, noted: "Everyone's scrambling. If China shuts the taps, entire supply chains collapse."
Correction: An earlier version misstated the current US tariff rate on Chinese imports. The correct figure is approximately 156%.
