In a recent summit between U.S. President Donald Trump and Chinese President Xi Jinping, the two superpowers agreed to a one-year delay on new Chinese export controls on rare earth elements (REEs). However, this is merely a short-term fix for a deep-seated vulnerability in global supply chains. With China controlling nearly 90% of the REE market, the world cannot rely on Beijing's goodwill. Critical Metals Corp (NASDAQ: CRML) and its Tanbreez project in Greenland are emerging as a beacon for Western independence, offering a path to secure supplies of these critical minerals.
Rare earths, which include 17 chemically similar elements like neodymium, dysprosium, and terbium, are essential for modern technologies—from electric vehicles and wind turbines to smartphones and missile guidance systems. Demand is expected to quadruple by 2040, according to the International Energy Agency, yet prices remain volatile due to supply fears.
China's dominance is state-orchestrated. In October 2025, Beijing imposed stricter export controls on REEs and magnets, targeting U.S. defense supply chains. This follows a history of "rare earth diplomacy," such as the 2010 embargo on Japan. While the recent truce pauses escalation, existing restrictions remain, and history shows China is willing to use supply as leverage.
Critical Metals Corp's Tanbreez project in Greenland is positioned to be a game-changer. Tanbreez is one of the world's largest undeveloped REE deposits, estimated at 4.7 billion metric tons, rich in heavy rare earth oxides (HREOs) like dysprosium and terbium—critical for high-performance magnets that China currently controls. Key highlights include its advanced stage: fully permitted, with recent drilling yielding 0.40-0.42% total rare earth oxides (TREO) and 26% HREO, top-tier grades. A bankable feasibility study is expected in 2025. Offtake agreements have been secured, with 25% of near-term output locked for U.S. buyers, including REalloys, a rare U.S. magnet processor, and Ucore Rare Metals, a leader in rare metal technologies. The project has also raised $85 million in a PIPE, with the U.S. Export-Import Bank eyeing support.
The truce buys time, but long-term security demands homegrown capacity. Western initiatives include MP Materials expansion in the U.S., frameworks with Japan and Australia for mining and processing, and the EU's Critical Raw Materials Act targeting 10% global processing by 2030. Tanbreez aligns perfectly with these efforts, given Greenland's stability, U.S. alliances, and its focus on HREOs.
The bottom line is that the U.S.-China truce is only a temporary pain reliever. True resilience means mining and processing in the U.S., EU, or allied regions like Greenland. Critical Metals Corp is working at the forefront of supply sovereignty. As the West scrambles to shore up its rare earth supply chains, Tanbreez represents a long-term solution. The rare earths revolution starts here.
