China's Rare Earth Export Restrictions Pulled Downstream Industry Toward China, Landmark Study Finds

Highlights

• Economists Pothen and Fink found industrial relocation—not price manipulation—was China's primary motive for rare earth export restrictions.
• China's strategy combined export barriers with investments in specialized labor, research, and industrial clustering to create self-reinforcing agglomeration effects.
• The study distinguishes geological dependence from industrial dependence, warning that building a competing ecosystem is far harder than diversifying mines.
• Export restrictions made rare earth inputs cheaper inside China and more expensive abroad, accelerating migration of downstream manufacturing to Chinese supply chains.
• Though published in 2015, the framework aligns closely with today's rare earth geopolitics and China's dominant position in processing and components.
