US Dependency on Chinese Rare Earths: How Supply Chain Dominance Impacts American Defense

As geopolitical tensions rise, the critical role of rare earth minerals in modern defense manufacturing has brought America's reliance on China into sharp focus.

Key Highlights:
- Strategic Importance: Rare earth elements are vital for producing powerful magnets used in advanced military hardware, including F-35 fighter jets, missiles, drones, radars, and submarines.
- Chinese Monopoly on Processing: While China dominates roughly 90% of global rare earth processing capacity, the US previously imported about 75% of its rare earth materials from China between 2019 and 2022, creating potential vulnerabilities in long-term weapons manufacturing.
- US Mitigation Efforts: To counter this dependency, the US Department of Defense has invested over $439 million since 2020 to foster domestic mining, processing, and magnet-manufacturing capabilities.
