U.S. lawmakers have raised serious concerns about America’s heavy dependence on China for critical minerals. They warned that this reliance could seriously damage U.S. defence manufacturing during a crisis.
Speaking at a Congressional hearing on rebuilding supply chains, Senate Armed Services Committee Chairman Roger Wicker said that America’s dependence on China for critical minerals is one of its biggest strategic weaknesses. He stressed that these minerals are essential for producing advanced weapons systems, military equipment, and other key technologies.
Critical minerals, including rare earth elements, are used in fighter jets, missiles, submarines, radar systems, and communication devices. Lawmakers said that if China were to restrict or stop exports of these materials, it could severely disrupt U.S. defence production and harm the broader economy.
Senator Wicker warned that even the threat of cutting off rare earth exports would have brought American defence manufacturing “to its knees” and caused major economic damage.
During the hearing, the Pentagon defended its recent efforts to rebuild domestic supply chains. These efforts include controversial equity investments in mining companies and price guarantees to encourage companies to produce critical minerals within the United States. Defence officials argued that such measures are necessary to reduce dependence on foreign suppliers and strengthen national security.
Lawmakers from both parties agreed that the U.S. must increase domestic production and diversify supply sources to avoid future risks. The issue has become more urgent amid rising tensions between Washington and Beijing.
The hearing highlighted growing bipartisan concern over supply chain security and the need to ensure that the U.S. military remains prepared even during global disruptions.
