China hopes that the World Health Organization will genuinely treat the COVID-19 origin-tracing work as a scientific issue, get rid of political interference, and actively and prudently promote the tracing work to be carried out continuously in multiple countries and regions around the globe, said a senior official of the National Health Commission (NHC) on Thursday.
What has been carried out in the first stage of origin tracing, especially those that have reached a clear conclusion, should not be repeated, said Zeng Yixin, deputy head of the NHC, at a press conference on the COVID-19 origin-tracing work.
