The motives and goals of the Biden administration are clear, Foreign Ministry spokesman Zhao Lijian noted, speaking of President Joe Biden's instruction to the intelligence services to submit a report on the origin of the new coronavirus.

The dark history of the US intelligence community has long been known to the world, he added, referring to the unfounded US accusations against Iraq of using weapons of mass destruction that led to their invasion of the country.

According to Lijian, the revival of laboratory leakage theory is disrespectful to science and also undermines the global fight against the pandemic.
