Zhao Lijian, spokesman of China's foreign ministry, responded on the 9th that the US government, in order to maintain its monopoly and hegemony in science and technology and curb China's development, has repeatedly generalized the concept of national security, abused state power and entity list, and tried every means to suppress China's high-tech enterprises. China firmly opposes this. China will take necessary measures to resolutely safeguard the legitimate rights and interests of Chinese enterprises.
