Expert: COVID-19 origin tracing should be objective, science-based

The U.S. has released a declassified intelligence report on COVID-19 origins. As expected, the report fails to draw any conclusions on where the virus comes from. A US expert said in an interview that the world needs an objective, science-based investigation into the origins of COVID-19, instead of some intelligence exercise of trying to prove that the virus came from a Wuhan lab. Jeffrey Sachs, a professor at Columbia University, also noted that the U.S. should stop groundless accusations against China and cooperate with the country and the rest of the world to curb the pandemic.
