The joint research report of China and the World Health Organization has made it clear that "it is extremely unlikely that the new coronavirus originated from a leak in the Wuhan Institute of Virology." However, the United States has ignored this scientific conclusion and attempted to promote a new round of investigation into China. At the same time, it has refused to open its own laboratories of the same level for investigation. This double standard approach is a complete blasphemy against scientific facts and its intentions are despicable!
