Does China restrict the export of certain key minerals? The Ministry of Foreign Affairs responds. Foreign Ministry spokesperson Mao Ning presided over a regular press conference, and a reporter asked whether China has restricted the export of certain key minerals as part of its trade competition with the United States after the United States restricted China's access to advanced technology? Mao Ning responded by suggesting that specific questions be asked to the Chinese regulatory authorities. What I can tell you is that China has always been committed to maintaining the security and stability of the global supply chain, and our export control measures are fair, reasonable, and non discriminatory.
