What makes export controls on critical minerals so powerful?
Core argument: U.S. Geological Survey researchers estimate that a 30% disruption to U.S. supply of the rare-earth element neodymium alone would cut U.S. GDP by 2.2%, more than $600 billion.
Chinese rare earths offer a clear-cut case. In 2024, China earned approximately $3.4 billion from exporting rare-earth elements and magnets. Meanwhile, researchers at the U.S. Geological Survey estimate that a 30% disruption to the United States’ supply of the rare-earth element neodymium alone would reduce the country’s GDP by 2.2 percent—more than $600 billion. In other words, China would have to forgo no more than a couple of billion dollars in export revenue to inflict over half a trillion dollars of damage on the U.S. economy. This asymmetry is what gives Chinese export controls their power. It also highlights a broader reality about economic warfare. When they have a choice, states don’t weaponize interdependence—they weaponize dependence.
