Understanding the Basics: What Are Critical Minerals?
Critical minerals are raw materials deemed essential for economic and national security, yet vulnerable to supply chain disruptions. These include rare earth elements (REEs) like neodymium and dysprosium, as well as minerals such as antimony, bismuth, cobalt, gallium, and tungsten. Unlike common minerals, these resources combine strategic importance with limited availability and geopolitical complexity.
The U.S. Geological Survey officially designates 50 minerals as "critical," with 24 specifically highlighted for defense applications. These minerals form the foundation of modern technology, from smartphones to fighter jets, and increasingly, critical minerals in energy transition.
Definition & Examples
Critical minerals are characterized by three key factors:
- Strategic importance: Essential for advanced technologies, defense systems, or energy transition
- Supply risk: Concentrated production in a limited number of countries
- Limited substitutability: Few or no viable alternatives exist for their applications
The most prominent critical minerals include:
- Rare Earth Elements (REEs): A group of 17 chemically similar metallic elements used in magnets, catalysts, and electronics
- Antimony: Enhances flame resistance in military vehicle components
- Bismuth: Used in medical applications and as a lead replacement
- Tungsten: Vital for hardening steel in defense applications
- Cobalt: Essential for lithium-ion batteries and jet engines
- Gallium: Used in semiconductors, LEDs, and 5G infrastructure
Why Are They "Critical"?
Critical minerals earn their designation through a complex interplay of technological necessity and geopolitical vulnerability. Their criticality stems from three primary factors:
Essential Applications
These minerals form the backbone of modern technology and defense systems:
- High-tech electronics: Smartphones, computers, and advanced sensors
- Defense systems: Guidance systems, night vision, and communications equipment
- Clean energy: Wind turbines, solar panels, and electric vehicle batteries
"The clean energy transition alone is projected to increase demand for critical minerals by 500% by 2050, creating unprecedented pressure on global supply chains," according to World Bank estimates.
Supply Chain Vulnerabilities
The production of critical minerals is highly concentrated, creating significant supply risks:
- China controls approximately 70% of global rare earth production
- The U.S. imports 70% of its rare earth elements from China
- For some minerals like gallium, U.S. dependence on Chinese imports reaches as high as 92%
Processing Bottlenecks
Mining is only part of the equation; refining and processing create additional vulnerabilities:
- China refines 90% of global cobalt and lithium
- Specialized processing facilities take years and billions to develop
- Environmental regulations in Western nations increase production costs
How Did Critical Minerals Become a Strategic Lever for China?
China's dominance in critical minerals didn't happen by accident. Through decades of strategic investment and policy support, Beijing transformed what was once considered a niche mining sector into a powerful geopolitical lever. This evolution represents one of the most successful examples of industrial policy in modern history.
China's Dominance by the Numbers
China's control over critical minerals extends far beyond its borders, creating global dependencies that provide significant geopolitical leverage:
| Mineral | China's Global Production Share | China's Global Processing Share | Primary Applications |
|---|---|---|---|
| Rare Earth Elements | 70% | 85% | Magnets, electronics, defense |
| Gallium | 80% | 95% | Semiconductors, 5G |
| Graphite | 65% | 85% | Batteries, aerospace |
| Bismuth | 82% | 80% | Medical, metallurgy |
| Antimony | 55% | 65% | Flame retardants, batteries |
This dominance extends throughout the supply chain:
- Mining: Massive operations in Inner Mongolia, Sichuan, and Jiangxi provinces
- Processing: Concentrated in specialized industrial parks in Ganzhou and Baotou
- Manufacturing: Vertical integration with magnet production and component assembly
- Export controls: 14 strategic minerals placed under export restrictions since 2024, including recent China export controls on bismuth
Development of Strategic Weaponization
China's transformation from mineral producer to geopolitical player evolved over several decades:
1980s-1990s: Foundation Building
- Chinese leadership identified rare earths as a strategic sector
- Government subsidies encouraged mining expansion
- Environmental regulations remained minimal, lowering production costs
2000s: Market Dominance
- Western mines closed, unable to compete with Chinese prices
- China acquired foreign mining assets and processing technology
- The industry consolidated under state-influenced companies
2010s: First Strategic Applications
"Beijing's 2010 rare earth embargo against Japan previewed current tactics," notes SCMP analyst Fan Chen. "When territorial disputes arose over the Senkaku/Diaoyu Islands, China demonstrated that mineral access could be weaponized."
That 2010 embargo sent a clear message:
- Rare earth prices surged 97% within months
- Japanese manufacturers scrambled for alternatives
- Western nations began reassessing supply vulnerabilities
2020s: Systematic Leverage
China's approach has become increasingly sophisticated:
- Targeted export controls now align with broader trade objectives
- 2024: Germanium exports restricted after Netherlands joined U.S. semiconductor controls
- Customs authorities intensified scrutiny of mineral shipments under export control laws
"Critical minerals, such as rare earth elements, have emerged as tools of geopolitical strategy, where national control equates to significant global leverage."
Why Are Critical Minerals Particularly Vulnerable in the Ongoing US-China Trade Conflict?
The critical minerals in US-China trade war represent a perfect storm of vulnerability in the escalating tensions between the two powers. Unlike other trade categories, minerals combine strategic importance with extreme supply concentration and limited substitutability.
US Dependency on Chinese Supply Chains
American dependence on Chinese minerals extends far beyond simple trade statistics, creating vulnerabilities that affect core national security capabilities:

How Does China's Leverage on Critical Minerals Influence Ongoing Trade Negotiations?
China's mineral dominance provides significant negotiating leverage across multiple domains of U.S.-China relations. This influence extends far beyond simple commodity pricing, affecting technology transfer, tariff structures, and broader geopolitical positioning.
Strategic Advantages for Beijing
China's mineral control creates multiple negotiating advantages:
Targeted Pressure Points
- China can selectively adjust mineral quotas to specific U.S. industries
- Export license approvals can be slowed without formal policy changes
- Technical specifications and testing requirements can be modified to create de facto barriers
Bargaining Power Enhancement
- 2024 U.S. tariff exclusions covered 78% of mineral-dependent products
- May 2025: China offered a 10% REE quota increase if the U.S. lifted certain drone export bans
"Beijing dangles REE quotas to extract tech concessions," explained a former USTR official who requested anonymity. "When the U.S. pushes on semiconductors, China responds with minerals. It's become a predictable pattern."
Response Flexibility
China's "Dual Circulation" strategy explicitly links mineral exports to semiconductor imports, creating a formal framework for reciprocal measures. This provides Beijing with:
- Justification for export restrictions under national security grounds
- Ability to calibrate responses proportionally to U.S. actions
- Domestic legitimacy for trade measures as "defensive" rather than aggressive
Broader Economic and Diplomacy Impacts
The minerals leverage extends beyond bilateral relations to reshape global alignments:
Third-Party Effects
- European manufacturers face procurement challenges when caught in U.S.-China tensions
