China said Monday it was "extremely unlikely" COVID-19 came from a laboratory, after the CIA said it believed the virus had more likely come from a lab rather than natural transmission.

"The conclusion that a laboratory leak is extremely unlikely was reached by the China-WHO joint expert team based on field visits to relevant laboratories in Wuhan," foreign ministry spokeswoman Mao Ning said.

"This has been widely recognized by the international community and the scientific community," she added.

The CIA said Saturday the virus was "more likely" leaked from a Chinese lab than transmitted by animals.

The new assessment came after John Ratcliffe was confirmed last week as CIA director in the President Trump's second administration.

"CIA assesses with low confidence that a research-related origin of the COVID-19 pandemic is more likely than a natural origin based on the available body of reporting," a CIA spokesperson said in a statement Saturday, adding that, "CIA continues to assess that both research-related and natural origin scenarios of the COVID-19 pandemic remain plausible."

The agency hadn't previously made any determination on whether COVID had been unleashed by a laboratory mishap or spilled over from animals.

Beijing on Monday urged the United States to "stop politicizing and instrumentalizing the issue of origin-tracing."

Mao said Washington should "stop smearing and shifting the blame to other countries (and) should respond to the legitimate concerns of the international community as soon as possible."
