5天3问稀土，特朗普很急，但先别急，把和中国的承诺兑现了再说

Group 1 - The U.S. Trade Representative reported that China agreed to lift export countermeasures imposed after April, including restrictions on rare earth minerals and magnets, although no changes were made to rare earth export controls [1] - China holds 70% of global rare earth mining and 92% of refining capacity, making it a dominant player in the rare earth supply chain [4] - The U.S. has been slow to develop its rare earth sector due to environmental regulations and high costs, with companies like Neo Performance Materials stating that it takes at least 29 years to establish a rare earth mine in the U.S. [3] Group 2 - Rare earths are critical for high-tech and military industries, used in advanced equipment such as F-35 fighter jets and renewable energy technologies [4] - Recent reports suggest that China issued four rare earth export licenses, the first since imposing restrictions on certain rare earths, which may be a strategic move ahead of negotiations [6] - The U.S. military and energy sectors are heavily reliant on rare earths, and China's control over pricing and supply has led to significant price increases, with dysprosium prices in Europe rising over 200% [6][8] Group 3 - The U.S. has attempted to reduce reliance on Chinese rare earths through various measures, but lacks the necessary separation and purification technology, making it difficult to rebuild the supply chain [6][8] - Analysts indicate that rebuilding a complete rare earth supply chain outside of China could take 10 to 15 years, during which time U.S. industrial security may be compromised [8]
