Beijing has criticized Washington for adding several Chinese companies to a list of entities allegedly supporting China's military, urging the United States to "correct its erroneous practices".
On Monday, the US Defense Department added several major Chinese companies, including Alibaba, Baidu and BYD, to the list, according to US media.
Responding at a daily news briefing in Beijing on Tuesday, Foreign Ministry spokesman Lin Jian said, "China has consistently and firmly opposed the US overstretching the concept of national security and formulating various types of discriminatory lists to go after Chinese businesses.
"We urge the US to correct its erroneous practices and stop its unwarranted suppression of Chinese enterprises," Lin said.
China will take necessary measures to firmly safeguard the legitimate rights and interests of Chinese enterprises, he added.
