China says it's "extremely unlikely" that COVID-19​ came from a lab, after the CIA said it believed​, though with low confidence, that it did, rather than from natural transmission.

The virus that started the COVID-19 pandemic most likely originated from a lab in China, the CIA said in a new assessment, though it has no conclusive evidence.

The CIA has changed its assessment on the origins of the COVID-19 pandemic, now favoring the lab leak theory. But some worry this could be an indication of politicization.
