US President Joe Biden has called on intelligence officials to “redouble” their work to find out how the virus was first transmitted to humans.
China’s foreign ministry accused the US of “political manipulation and blame shifting”. It has rejected any link between Covid-19 and a virus research lab in the Chinese city of Wuhan
Covid-19 was first detected in Wuhan in late 2019. Since then, more than 168 million cases have been confirmed worldwide and about 3.5 million deaths reported.
Authorities linked early Covid cases to a seafood market in Wuhan, leading scientists to theorise that the virus had first passed to humans from animals, but recent US media reports have suggested growing evidence the virus could instead have emerged from a laboratory in China, perhaps through an accidental leak.
In a statement on Wednesday, President Biden said he had asked for a report on the origins of Covid-19 after taking office, “including whether it emerged from human contact with an infected animal or from a laboratory accident”. On receiving it this month, he asked for “additional follow-up”.
The majority of the intelligence community according to Mr. Biden had “coalesced” around those two scenarios, but “do not believe there is sufficient information to assess one to be more likely than the other”.
The US President said he had now asked agencies to “redouble their efforts to collect and analyse information that could bring us closer to a definitive conclusion”, an announcement which has angered Chinese officials.
Foreign ministry spokesman Zhao Lijian said it showed the US “does not care about facts or truth, and has zero interest in a serious science-based study of origins”.
The spokesman also said US intelligence agencies had a “dark history” of spreading misinformation.
A statement from the Chinese embassy in the US, which did not directly refer to Mr. Biden’s order, said “smear campaigns and blame shifting are making a comeback”.
