Core Viewpoint - The recent fluctuations in the S&P 500 index have brought China's upgraded rare earth control measures back into the global spotlight, highlighting the strategic importance of rare earths in international trade and geopolitical dynamics [2] Control Upgrade - The most notable breakthrough in rare earth control is the implementation of the "extraterritorial jurisdiction" mechanism, requiring any product containing 0.1% or more of Chinese-origin rare earths to obtain Chinese export permission, regardless of the company's location [4] - This regulation is based on China's dominant position in the rare earth industry, controlling 70% of global extraction, 90% of separation processing, and 93% of magnet manufacturing, making it difficult for other countries to operate independently of Chinese technology [4][6] - The newly enacted "Rare Earth Management Regulations" categorize rare earths as strategic resources, implementing an export approval system that requires detailed reporting of end-users and purposes [4] Precision Strategy - The control measures have led to a "protect civilian use, block military use" strategy, allowing short-term licenses for civilian needs while rejecting all military-related applications [6] - Reports indicate that the U.S. military supply chain is already feeling the pressure from shortages of rare earth magnets, which are critical for defense technologies like the F-35 fighter jet [8] Strategic Value - Rare earths are essential for modern industries, including electronics and defense, serving as a critical component in various technologies [10][11] - The demand for rare earths is surging due to the acceleration of the energy transition and advancements in industries such as robotics and wind power [13] U.S. Dilemma - Following China's control measures, the U.S. has threatened to impose high tariffs, revealing its reliance on Chinese processing technology despite having its own rare earth resources [15] - The U.S. is attempting to build alternative supply chains by partnering with third-party resource countries, but challenges remain, particularly with Brazil's Serra Verde mine, which has long-term contracts with Chinese companies [17] Supply Chain Challenges - The U.S. Department of Energy estimates that achieving rare earth self-sufficiency could take at least 10 years and would be 3-5 times more expensive than sourcing from China [19] - China's control measures are seen as a legitimate defense against unilateral protectionism, redefining the rules of engagement in the global supply chain [19] Dialogue Opportunities - Despite the tensions, both China and the U.S. have left room for dialogue, with provisions in the control measures allowing for emergency medical and disaster relief needs [21] - The rare earth competition reflects a broader adjustment in global supply chain rules, with China leveraging its industrial advantages to establish a more equitable framework [21][23]
