US vs China: The Battle for Rare Earth Processing Dominance and What It Means for Investors

The global race for technological supremacy is increasingly fueled by a hidden element: rare earth elements (REEs). These 17 metallic elements, vital for everything from smartphones to electric vehicles and defense systems, are at the heart of a strategic competition between the United States and China. China’s dominance in rare earth processing has created a significant vulnerability for the US and its allies, prompting a concerted effort to re-establish a domestic supply chain. This article delves into the US vs China battle for rare earth processing dominance, exploring the implications for investors and the future of critical technology industries.

The Rare Earth Element Landscape: A Primer
