China’s Ministry of Industry and Information Technology introduced new interim measures in 2025 to tighten control over rare earth mining and processing. These rules aim to centralise oversight on extraction, exports, and refining. This move comes amid rising global concerns over supply security, especially from countries like India and the United States. China’s dominance in rare earth elements (REEs) is not only due to its resource availability but also its advanced mining and research capabilities.
Overview of Rare Earth Elements
Rare earth elements consist of 17 metals divided into light rare earths (LREEs) and heavy rare earths (HREEs). LREEs include lanthanum, cerium, and neodymium, while HREEs include dysprosium, terbium, and yttrium. Promethium is excluded as it is radioactive and not found in mineable quantities. REEs are vital for clean energy, defence, and high-tech devices like smartphones and electric vehicles.
China’s Resource and Production Strength
China holds nearly half of the world’s rare earth reserves. It has been the largest global producer, contributing over 60% of production in the past five years. Besides extraction, China controls about 92% of global refining capacity, making it dominant across the entire value chain from mining to processing.
Export Restrictions and Global Impact
Recently, China imposed export restrictions on seven rare earth elements critical for clean energy magnets and aerospace materials. This action was part of ongoing trade tensions with the U.S. and has impacted global supply chains. The U.S. is the second-largest importer of Chinese rare earths after Japan. India also depends heavily on China, sourcing over 75% of its rare earth imports from there since 2021.
Government Control and Industry Regulation
China’s new interim measures require companies to operate within government-set quotas and obtain approvals for trading rare earths. These regulations follow previous bans on exporting extraction tools and processing technology. The government’s tight control aims to secure strategic resources amid geopolitical tensions.
Research and Investment Leadership
China leads in rare earth research, producing nearly 30% of global scientific publications on the subject. The U.S. and Japan trail with less than 10% each, while India contributes about 6%. China has also increased funding for mineral exploration, investing roughly $14 billion annually since 2022, marking the highest level of investment in a decade.
Strategic Importance of Rare Earths
Rare earth elements are essential for modern technologies including electric vehicles, wind turbines, and defence systems. Control over these resources influences global technological advancement and geopolitical power. China’s monopoly poses challenges for other nations seeking to diversify supply and develop indigenous capabilities.
