"As for the so-called leak of the virus and other assumptions, they have no scientific evidence", Zhao said at a briefing.
Earlier in the day, the Fox News broadcaster reported, citing informed sources, that the first carrier of COVID-19 had worked in the laboratory of the Wuhan Institute of Virology. Sources who have seen some classified materials believe that the coronavirus originated in the laboratory not as a bioweapon, but as part of Beijing's intention to show the United States its greater capabilities in the field of identifying and combating viruses.
US Joint Chiefs of Staff Chairman Mark Milley told reporters on Tuesday that "the weight of evidence" seemed to indicate that the ongoing coronavirus pandemic had natural causes. He admitted, however, that the data available to the US military on the matter looked "inconclusive".
Various media outlets have published reports suggesting China created the coronavirus, which has caused the ongoing deadly outbreak, in a laboratory in Wuhan. China has repeatedly dismissed these claims and called on Washington to stop shifting responsibility for wasting time it had to prepare for the pandemic on others.
