China's Foreign Ministry spokesperson Mao Ning responded to the U.S. government's directive requiring federal agencies to cease using Chinese artificial intelligence products, including DeepSeek, citing concerns over sensitive data transfers. During a regular press conference on October 20, Mao stated that China has consistently opposed the overextension of national security concepts and the politicization of science, technology, and economic trade issues. The Foreign Ministry affirmed its commitment to resolutely safeguarding the legitimate rights and interests of Chinese enterprises in response to the U.S. restrictions. The ban marks an escalation in regulatory actions targeting Chinese AI tools within U.S. government infrastructure.
