China Curbs Rare Earth Exports to Japan
China has imposed new export restrictions on 20 Japanese entities, targeting rare earth elements and other advanced materials crucial for high-tech manufacturing. The measures, which affect units of major Japanese firms, are officially a response to concerns over Japanese "remilitarization." The move is expected to impact global supply chains for electronics, automotive, and defense industries and may accelerate diversification away from Chinese suppliers.
- This is not the first time China has restricted rare earth exports to Japan; in 2010, China cut off supplies following a collision between a Chinese fishing trawler and Japanese coast guard vessels. That incident prompted Japan to reduce its reliance on Chinese rare earths from 90% of its supply to the current 60%. - China's leverage comes from its dominance in processing; while it accounts for about 60% of global rare earth mining, it refines and processes nearly 90% of the world's supply. It also produces 94% of the world's rare earth permanent magnets, which are critical for high-tech manufacturing. - Since the 2010 embargo, Japan has actively worked to diversify its supply chain by stockpiling reserves, investing in overseas mining projects in countries like Australia, and funding recycling initiatives. - The new export controls are more sweeping than past measures, extending beyond raw materials to restrict the transfer of technological know-how. The rules also have an extraterritorial reach, requiring Beijing's approval for foreign-made goods that use Chinese rare earth technology or materials. - The United States, which sources approximately 70% of its rare earth imports from China, has labeled the export controls "economic coercion." In response to China's broader use of such restrictions, the G7 nations have pledged a united front, and the EU has launched initiatives to build its own independent supply chains. - Rare earths are essential components in a wide range of defense and commercial technologies, including fighter jets, missile guidance systems, electric vehicles, wind turbines, and consumer electronics.
