According to media reports, citing Microsoft, China is alleged to have established a network of fake social media accounts with the aim of influencing US voters through artificial intelligence.
"In recent years, some western media and think tanks have accused China of using artificial intelligence to create fake social media accounts to interfere in US politics," Liu said on Thursday.
"Such remarks are full of prejudice and malicious speculation against China, which China firmly opposes."
Liu added that the PRC actively favors using artificial intelligence in a safe, reliable and controlled manner.
The social media platforms apparently affected by the Chinese operation appear to be Facebook* and X, formerly known as Twitter, media reported.
