China has announced the addition of five more rare earth elements—holmium, erbium, thulium, europium, and ytterbium—to its export control list, effective from November 8, 2025. This move tightens Beijing's grip on the global supply of these critical materials ahead of upcoming talks between US President Donald Trump and Chinese President Xi Jinping, escalating trade tensions and highlighting concerns over national security and high-tech dependencies.
What Are Rare Earth Elements and Their Basic Characteristics?
Definition and Group: Rare earth elements (REEs) are a set of 17 metallic elements in the periodic table, including 15 lanthanides (from lanthanum to lutetium) plus scandium and yttrium; they are called "rare" not because they are scarce in the Earth's crust but due to their dispersed occurrence and the complex, costly process of extraction and separation.
Key Properties: These elements possess unique magnetic, luminescent, catalytic, and electrochemical properties that make them indispensable in modern technology; for instance, they enable stronger magnets, brighter phosphors, and efficient catalysts, often in small quantities that significantly enhance product performance.
Global Reserves and Production: The world's proven REE reserves are estimated at about 120 million tonnes, with China holding around 44 million tonnes (37%), followed by Vietnam (22 million), Brazil (21 million), and India (6.9 million); however, China dominates processing with over 90% of global capacity, achieved through state support and integrated mining-refining chains.
Extraction Process: REEs are mined from ores like bastnasite and monazite, often as by-products of other mining; processing involves crushing, flotation, acid leaching, and solvent extraction, which is energy-intensive and environmentally challenging, producing radioactive waste and requiring strict pollution controls.
Historical Significance: Discovered in the late 18th century in Sweden (hence names like ytterbium from Ytterby village), REEs gained importance during the Cold War for defense tech; China's rise began in the 1980s, leading to market dominance by the 2000s.
Why Has China Imposed Export Controls on Rare Earth Elements?
National Security Concerns: China cites the dual-use nature of REEs, which have applications in defense (e.g., radar systems, missiles) and high-tech (e.g., EVs, semiconductors), to justify controls; the curbs prevent technology transfer that could enhance foreign military capabilities.
Retaliation in Trade War: Amid US tariffs and export bans on AI chips, China uses its REE dominance as leverage; previous curbs in April 2025 caused global shortages, and this expansion counters US efforts to restrict Chinese access to advanced tech.
Strategic Economic Goals: Under initiatives like "Made in China 2025," Beijing aims to retain value-added processing domestically, encouraging foreign firms to invest in China and reducing reliance on exports of raw materials.
Timing and Context: Announced on October 9, 2025, ahead of the tariff truce deadline and Trump-Xi talks, it signals Beijing's unwillingness to concede without US compromises, mirroring US CHIPS Act restrictions.
What Are the Five New Rare Earth Elements Added to the Controls and Their Uses?
Holmium: Used in semiconductors, magnets, laser surgery devices, and control rods for nuclear reactors; its magnetic properties make it ideal for high-strength fields in medical and energy applications.
Erbium: Primarily employed in fiber-optic telecommunications and infrared technology; erbium oxide is used to produce infrared-absorbing glass, enhancing signal amplification in long-distance cables.
Thulium: Applied in X-ray equipment, laser technology, and ceramics for microwaves; it fluoresces under UV light, making it useful for anti-counterfeiting measures in currency and documents.
Europium: The most reactive REE, also fluorescent; it is used in control rods for nuclear reactors and glowing materials for medical imaging, like phosphors in CT scans and LEDs.
Ytterbium: The most volatile REE; it serves as a radiation source in X-rays and has applications in nuclear medicine, such as in cancer treatments and diagnostic tools.
What Is the Broader Context of the US-China Trade War?
Origins and Escalation: The trade war started in 2018 with US tariffs on Chinese goods to address imbalances (US deficit over $300 billion annually), IP theft, and subsidies; by 2025, US "Liberation Day" tariffs targeted tech sectors, prompting Chinese retaliations like REE curbs.
Key Agreements and Truces: A 90-day truce began August 11, 2025, pausing escalations for negotiations; partial deals resolved issues like TikTok, but core disputes over tech exports and subsidies persist.
Global Trade Data: US-China bilateral trade was $575 billion in 2024, down from peaks due to tariffs; China exports 80% of US REE needs, while the US supplies 20% of China's semiconductors.
Impact on Other Countries: The EU imports 98% of its REEs from China and is investing €10 billion in diversification; India, with 6% of global reserves, imports 95% of processed REEs from China, affecting its $200 billion electronics sector.
How Do These Controls Affect Global Supply Chains?
Potential Disruptions: With China processing 90% of REEs, curbs could raise prices (e.g., neodymium up 20% post-announcement) and cause shortages in EVs (requiring 2-3 kg REEs per vehicle) and renewables (wind turbines use 200 kg per MW).
Diversification Initiatives: The US is boosting domestic production (e.g., MP Materials at Mountain Pass) and alliances like the Quad Critical Minerals Partnership with India, Japan, and Australia; global REE mining output rose 15% in 2024 to 300,000 tonnes.
Economic Implications: Foreign firms using Chinese REEs must now license exports of final products from December 1, 2025, potentially adding costs and delays; stock markets reacted with REE miners gaining 5-10%.
Environmental Aspects: REE mining's pollution drives sustainable alternatives; recycling REEs from e-waste could meet 10% of demand by 2030, reducing reliance on China.
What Is the Significance for India and Its Rare Earth Sector?
India's Dependence: India imports nearly all processed REEs from China for defense (e.g., radar in Tejas jets) and EVs (targeting 30% market share by 2030); curbs could increase costs by 15-20% for industries like renewables.
Domestic Resources: India has 6.9 million tonnes of reserves, mainly monazite sands in Kerala and Odisha; Indian Rare Earths Ltd (IREL) produces 5,000 tonnes annually, but processing capacity is limited.
Government Efforts: The 2021 Mines and Minerals Act amendments promote exploration; partnerships with Australia for REE processing and Quad initiatives aim for self-reliance; budget allocations for critical minerals rose 50% in 2025.
Opportunities: Trade tensions could boost India's role in alternative supply chains; exports of REE compounds grew 20% in FY24, with potential in high-tech manufacturing under PLI schemes.
