把稀土技术管起来，谁私卖，谁就是出卖国家安全和利益！

Core Viewpoint - The announcement of China's export controls on rare earth technologies coincides with the G7 and EU's plans to impose taxes on Chinese rare earths, highlighting a complex geopolitical landscape where Western nations seek to limit China's advantages while also desiring access to its resources and technologies [1][5]. Group 1: China's Export Control Measures - On October 9, China announced export controls on rare earth-related technologies to safeguard national security and interests, emphasizing that any unauthorized disclosure of these technologies will face severe legal consequences [7][11]. - The export controls encompass various technologies related to rare earth mining, smelting, metal processing, and magnet manufacturing, including installation, debugging, and maintenance of production lines [11]. Group 2: China's Technological Advantage - China holds over 90% of the global rare earth refining capacity, achieving remarkable efficiency and purity levels exceeding 99.99%, making it difficult for other countries to catch up [5][9]. - The development of China's rare earth refining technology has been a gradual process since the 1980s, where it took on challenging tasks and overcame technical bottlenecks to achieve a leading position in the industry [9]. Group 3: Geopolitical Implications - The export control measures are seen as a response to Western nations' strategic attempts to undermine China's technological capabilities in various sectors, including semiconductors and lithography [11]. - This move serves as a strategic defense in the ongoing trade war and supply chain tensions, emphasizing that technological control is crucial for maintaining competitive advantages in the global market [11].
