US-China Rare Earth Tensions: How Flight Restrictions Could Impact Global Supply Chains
The recent call by US Representative John Moolenaar to restrict Chinese airline landing rights represents a significant escalation in the ongoing rare earth materials dispute between the United States and China. This Republican lawmaker, who chairs a House committee on China, has proposed these aviation restrictions as leverage to counter China's tightening control over critical minerals energy security. Moolenaar's proposal specifically aims to pressure Beijing to restore full access to rare earth materials and magnets by targeting a strategic Chinese economic sector.
The congressman's statement emphasizes that these measures would "send a clear message to Beijing that it cannot choke off critical supplies to our defense industries without consequences to its own strategic sectors."
The Strategic Value of Rare Earth Elements in Global Security
Rare earth elements play a crucial role in modern defense systems, renewable energy technologies, and consumer electronics. These materials are essential components in everything from precision-guided missiles and radar systems to wind turbines and electric vehicle motors.

- Clean energy technologies depend heavily on rare earth magnets for efficiency and performance
- Consumer electronics manufacturers rely on these materials for miniaturization and functionality
- Advanced manufacturing processes incorporate rare earth elements in various precision tools
This concentration of critical applications makes rare earth supply chains a matter of national security for many countries, particularly the United States, which has recently moved to develop Australia's strategic reserve as an alternative source.
How Did China Gain Control Over Global Rare Earth Supplies?
China's Dominance in the Rare Earth Supply Chain
China has systematically developed its rare earth industry over decades, establishing dominance across the entire supply chain:
| Supply Chain Stage | China's Global Share (2025) | Strategic Significance |
|---|---|---|
| Mining Production | ~58% | Controls raw material access |
| Processing Capacity | ~85% | Bottleneck for refined materials |
| Magnet Manufacturing | ~90% | Critical for high-performance applications |
| End-product Integration | Significant | Leverage over finished goods |
This comprehensive control allows China to exert influence over global markets through export policies, creating vulnerability for countries dependent on these materials. The impact of this dominance has been particularly evident in the ongoing US–China trade war impact on various industries.
Historical Development of China's Rare Earth Strategy
China's dominance didn't happen overnight. The country implemented a long-term strategy that included:
-
Identifying rare earth elements as strategic resources in the 1980s
-
Investing heavily in mining technology and processing capabilities
-
Implementing favorable regulatory policies to support industry growth
-
Accepting environmental impacts that other nations avoided

Developing domestic expertise in advanced applications
By 2025, this strategy has positioned China as the gatekeeper for materials essential to advanced technology and defense systems worldwide.
What Are the Recent Export Controls That Triggered This Dispute?
China's 2025 Rare Earth Export Restrictions
In 2025, China implemented strict export controls on seven critical medium and heavy rare earth elements:
- Samarium
- Gadolinium
- Terbium
- Dysprosium
- Lutetium
- Scandium
- Yttrium
These export controls require Chinese companies to obtain special licenses before shipping these materials internationally, effectively creating a mechanism to restrict Chinese flights over rare earths and other strategic commodities at will.
Impact on Global Supply Chains
The immediate effects of these export controls include:
- Price volatility in global rare earth markets
- Supply uncertainty for manufacturers reliant on these materials
- Accelerated efforts to develop alternative supply chains
- Diplomatic tensions between China and rare earth-dependent nations
- Strategic reconsideration of critical mineral policies in Western countries
For US defense contractors, these restrictions create particular challenges as many systems rely on Chinese-sourced materials that now face uncertain availability.
How Would Airline Restrictions Work as a Counter-Measure?
The Proposed Aviation Restrictions
Representative Moolenaar's proposal involves:
- Restricting or suspending Chinese airline landing rights in the United States
- Reviewing export control policies for commercial aircraft sales to China
- Potentially limiting parts and maintenance services for Chinese commercial aviation
These measures target China's aviation sector, which relies heavily on international connectivity and Western aerospace technology. The approach bears similarities to Trump's critical minerals order which sought to secure American supply chains.
Strategic Rationale Behind Aviation Restrictions
The aviation sector represents a strategic vulnerability for China for several reasons:
-
Chinese airlines depend on international routes for revenue and growth
-
The country's commercial aviation fleet still relies significantly on Western aircraft
-
Maintenance and parts supply chains involve international cooperation
-
Aviation represents a high-profile sector with economic and prestige implications
By targeting this sector, US policymakers aim to create leverage comparable to China's control over rare earth supplies.
