China has said that it was shocked by the World Health Organisation's plan for Covid origin study and called the lab leak theory a rumour.

?A senior Chinese health official said Thursday he was shocked by the WHO’s plan for the second phase of a Covid-19 origins study.

National Health Commission Vice Minister Zeng Yixin dismissed the lab leak theory as a rumor running counter to common sense.

The head of the WHO acknowledged last week that it was premature to rule out a potential link between the pandemic and a leak of the coronavirus from a Chinese lab.

Zeng called the theory a rumor that goes against science.
