China Presents Sufficient Data for Origin Tracing

China had presented sufficient data in accordance with requests by experts from the World Health Organization's mission to China on the origins of the COVID-19 virus, said Liang Wannian, the team leader of the Chinese side of the China-World Health Organization joint expert team.

Liang said China had shared clinical data on early COVID-19 patients, information from epidemiological surveys and lab test results with the expert team for joint study and analysis, and the findings were later published in the WHO report.

However, Liang said, the data contained personal information, and it is against relevant laws and regulations in China to allow such data to be taken to other countries.
