Country in East Asia
China, officially the People's Republic of China (PRC), is a country in East Asia. It is the second-most populous country after India, with a population exceeding 1.4 billion, representing 17% of the world's population. China borders fourteen countries by land across an area of 9.6 million square ki...

Why It Matters
This 60 Minutes segment on rare earth elements highlights critical vulnerabilities in global supply chains that affect national security, technology manufacturing, and green energy transitions. The concentration of rare earth mining and processing in China creates strategic dependencies for Western nations, impacting defense contractors, electronics producers, and renewable energy companies. This matters because rare earths are essential components in everything from smartphones and electric vehicles to military guidance systems and wind turbines, making supply disruptions potentially catastrophic for multiple industries.
Context & Background
- Rare earth elements are 17 metallic elements crucial for modern technology despite their misleading name (they're relatively abundant but difficult to extract economically).
- China has dominated rare earth production since the 1990s, currently controlling approximately 60-70% of global mining and 85-90% of processing capacity.
- A 2010 diplomatic incident where China restricted rare earth exports to Japan revealed Western vulnerabilities, prompting renewed efforts to develop alternative sources.
- The Mountain Pass mine in California represents the only significant rare earth mining operation in the United States, though most material still goes to China for processing.
- Rare earths enable key properties in permanent magnets, phosphors, catalysts, and alloys that are irreplaceable in current technology designs.
What Happens Next
Increased investment in rare earth projects outside China will accelerate, particularly in Australia, the United States, and Canada, with several mines expected to reach production in the next 2-3 years. Governments will likely implement stronger stockpiling policies and supply chain security measures, while research into recycling rare earths from electronic waste will gain funding and attention. International trade negotiations will increasingly include rare earth access as a bargaining chip, and alternative technologies that reduce rare earth dependence may see accelerated development.
Frequently Asked Questions
Rare earth elements provide unique magnetic, luminescent, and electrochemical properties that are essential for miniaturized high-performance devices. They enable powerful permanent magnets in electric motors and wind turbines, phosphors in displays and lighting, and catalysts in petroleum refining and pollution control systems. No commercially viable substitutes exist for most of their applications in current technology designs.
Rare earth ores typically contain low concentrations of valuable elements mixed with radioactive thorium and uranium, requiring complex chemical separation processes. The extraction generates significant environmental waste including toxic tailings and radioactive byproducts. Economies of scale and decades of Chinese investment have created processing infrastructure that's difficult and expensive to replicate elsewhere with environmental regulations.
While technically possible, recycling faces major challenges including the diffuse distribution of small quantities in complex products, difficult separation processes, and collection logistics. Current recycling rates are below 1% for most rare earths, though research is improving methods. Economic viability remains limited compared to mining, but pressure on supplies may make recycling more attractive in coming years.
Military systems including fighter jets, missiles, satellites, and communication devices rely on rare earth elements for guidance systems, sensors, and power systems. Supply disruptions could impair defense manufacturing and maintenance capabilities. This vulnerability has prompted the U.S. Department of Defense to classify rare earths as critical materials and support domestic supply chain development through funding and policy initiatives.
Vietnam, Brazil, Russia, India, Australia, and the United States all have substantial rare earth reserves, with Vietnam ranking second globally. Greenland also has promising deposits that have attracted mining interest. However, having reserves doesn't equal production capacity—developing mines and processing facilities requires billions in investment and years of development, along with navigating environmental regulations and local opposition.
