U.S. officials issued new warnings Friday about China’s ambitions in artificial intelligence and a range of advanced technologies that could eventually give Beijing a decisive military edge and possible dominance over health care and other essential sectors in America, AP reported.

The warnings include a renewed effort to inform business executives, academics and local and state government officials about the risks of accepting Chinese investment or expertise in key industries, officials at the National Counterintelligence and Security Center said. While the center does not intend to tell officials to reject Chinese investment, it will encourage efforts to control intellectual property and implement security measures.

The counterintelligence center’s acting director, Michael Orlando, told reporters in a briefing that the U.S. “can’t afford to lose” ground to China in several key areas: artificial intelligence, autonomous systems, quantum computing, semiconductors, and biotechnology.

Orlando noted that Chinese businesses and academics are beholden to the Chinese Communist Party and are required to serve the party’s interests.

“Although we’ve been saying this for year after year, people are not digesting this,” he said.

Orlando declined to say whether the U.S. should enact tougher restrictions or outright bans on Chinese investment in certain sectors, saying his role was not to suggest policy.
