What Are Rare Earth Minerals and Why Are They Important?
Rare earth minerals comprise 17 chemical elements that, despite their name, are relatively abundant in the Earth’s crust. However, they rarely occur in concentrated deposits, making their extraction economically challenging and environmentally intensive. These elements fall into two main categories: light rare earths (including lanthanum, cerium, and neodymium) and heavy rare earths (such as terbium, dysprosium, and yttrium).
According to industry experts, these minerals represent “a fundamental piece in the supply chain of new technologies, and their geopolitics is shaping commercial and political relations worldwide” (Ámbito, September 2024). Their unique magnetic, luminescent, and electrochemical properties make them essential components in modern technology.
Critical Applications Across Industries
The applications of rare earth elements span multiple strategic sectors, each with specific requirements:
Clean energy technologies: Neodymium is essential for high-power magnets in electric vehicle motors and wind turbines, while europium is crucial for LED screens and energy-efficient lighting systems.
Defense systems: These minerals are irreplaceable in military applications—neodymium for missile guidance systems, samarium for radar equipment, and erbium for secure optical fiber communications.
Medical equipment: Gadolinium serves as a contrast agent in MRI machines, while holmium powers precise medical lasers for various treatments.
Electronics: Rare earths enable miniaturization and performance improvements in smartphones, computers, and other consumer devices. Lanthanum improves the quality of camera and telescope lenses, while europium creates vibrant colors in displays.
Industrial applications: These elements serve as catalysts, glass polishing compounds, and components in metallurgical processes that underpin manufacturing sectors.
The International Energy Agency projects that global demand for these critical minerals and energy security will multiply by four by 2040 (Ámbito, September 2024), driven by the transition to clean energy technologies and digital transformation.
China’s Strategic Dominance in the Rare Earth Market
How China Built Its Rare Earth Monopoly
China’s dominance in rare earths didn’t happen by accident but resulted from decades of strategic planning that began in the 1980s. The country’s leaders recognized the strategic value of these resources long before other nations did, famously captured in Deng Xiaoping’s statement that “the Middle East has oil; China has rare earth minerals.”
The Chinese strategy combined several critical elements: maintaining low labor costs, implementing flexible environmental standards, and establishing strong state control over the sector. This long-term vision allowed China to develop expertise across the entire supply chain—from mining and processing to manufacturing of finished products.
What began as a cost advantage gradually evolved into technological leadership, with China developing proprietary processing methods and accumulating intellectual property that further cemented its position. While other countries closed mines due to environmental concerns and economic pressure, China expanded its capacity and consolidated control.
Current Market Control and Production Capacity
Today, China’s position in the global rare earth market is overwhelming:
- Controls approximately 60% of global rare earth mining production (Ámbito, September 2024)
- Processes nearly 90% of all rare earth elements worldwide
- Supplies approximately 98% of the rare earths used in the European Union as of 2021
- Dominates the manufacturing of rare earth permanent magnets, essential for motors and generators
- Maintains strategic control over both light and heavy rare earth elements
This dominance extends beyond raw material production to processing technologies. On December 21, 2023, China’s Ministry of Commerce announced suspension of exports of technologies necessary for rare earth processing, further tightening its grip on the global supply chain.
China’s strategy now includes importing rare earth concentrates from other countries to maintain its processing monopoly, effectively controlling the most valuable part of the supply chain even when the raw materials come from elsewhere.
Historical Examples of Supply Restrictions
China has demonstrated multiple times that it’s willing to use its rare earth dominance as leverage in international disputes:
The 2010 Japan Dispute: Following territorial disagreements over the Senkaku/Diaoyu Islands, China restricted rare earth exports to Japan, causing prices to spike by up to 500% and severely disrupting Japan’s electronics manufacturing sector. This single action forced Japan to reconsider its entire approach to resource security.
US Trade War Tensions: During escalating trade tensions with the United States, China threatened to cut rare earth supplies, highlighting American vulnerability in critical technology supply chains and defense systems.
Recent Export Controls: In late 2023, China implemented new restrictions on gallium, germanium, and certain rare earth processing technologies amid growing global competition, signaling its willingness to use these resources as bargaining chips.
These actions have made rare earth supply security a national priority for countries around the world, with many scrambling to develop alternative sources and technologies to reduce their dependence on Chinese supplies.
Recent Policy Shifts and Export Restrictions
China’s approach to rare earth policy has evolved toward more sophisticated control mechanisms:
Domestic Industry Consolidation: The government has restructured the sector into larger state-controlled entities that can better manage production volumes and pricing.
Technology Export Controls: Beyond the materials themselves, China now restricts the export of processing technologies, creating an additional layer of dependency.
Strategic Stockpiling: The country has built reserves of key materials to better manage market dynamics and potential future restrictions.
Environmental Regulations: China increasingly uses environmental standards as a tool to control production volumes, allowing it to adjust supply without explicitly announcing export restrictions.
This comprehensive approach gives China multiple levers to pull in international negotiations, raising the stakes for countries dependent on these critical resources.
Global Response to China’s Rare Earth Dominance
United States Strategy and Initiatives
The United States has recognized rare earth dependency as a critical national security vulnerability requiring urgent action:
National Security Measures: In 2020, then-President Trump declared a national emergency regarding critical mineral supply chains and authorized federal funding for domestic mining projects (Ámbito, September 2024). This policy has continued under subsequent administrations with the US critical minerals order.
Defense Production Act: The Pentagon has invested hundreds of millions in rare earth projects to secure supply chains for military applications, backing companies developing domestic capacity.
Research Funding: Substantial grants support universities and national laboratories working on alternative technologies, recycling methods, and process improvements to reduce rare earth dependency.

International Agreements: The US has established partnerships with allied nations to diversify supply sources, exemplified by agreements with Argentina, Australia, and Canada.
Despite these efforts, building a complete supply chain outside China remains challenging due to high costs, regulatory hurdles, and technical complexity.
Efforts by Other Major Economies
Other countries and regions are implementing their own strategies to reduce China’s rare earth leverage:
European Union: Launched the European Raw Materials Alliance focused on building regional capacity, especially for magnet production. The EU aims to reduce its 98% dependency on Chinese imports through a combination of strategic partnerships, investments, and recycling initiatives.
Japan: Following the 2010 supply shock, Japan invested heavily in overseas mining operations, alternative technologies, and extensive recycling programs. Japanese companies have pioneered methods to recover rare earths from used electronics and industrial waste.
Australia: Leveraged its significant reserves to become the world’s second-largest producer of rare earth concentrates, though most still go to China for processing. Australia’s critical minerals strategy now focuses on developing domestic processing capacity.
Canada: Implemented a comprehensive critical minerals strategy with significant government support for exploration, extraction, and processing facilities, particularly targeting heavy rare earth elements.
These initiatives show how rare earth security has become a global priority, with countries approaching the challenge through different but complementary strategies.
