Group 1 - China has implemented strict export controls on critical high-tech materials, including rare earth elements, lithium batteries, and superhard materials, which are essential for various industries [1][2][3] - Rare earth elements are crucial for sectors such as automotive, military, and semiconductors, with the U.S. relying heavily on imports from China, accounting for 70% of its rare earth compounds and metals [2][3] - The export control on lithium batteries, where China holds a 70% manufacturing share, is expected to significantly impact the global electric vehicle market, with China's lithium battery exports reaching $245 billion, a 25% increase [3][4] Group 2 - The rationale behind these export controls is to maintain national security and interests, as these materials have dual-use properties, and to shift from a raw material selling model to one that emphasizes core technology and pricing power [4][5] - The controls are not an outright ban but involve strict scrutiny of buyers' motives and qualifications, which could lead to long-term benefits for the industry [5][6] - The strategic move reflects China's confidence in its industrial capabilities and resource richness, positioning itself strongly in global negotiations [4][6]
