BEIJING: China has been transparent in sharing research results on the origins-tracing of SARS-CoV-2 with the international community, a Chinese health official said at a press conference on Saturday.

'Since the outbreak of Covid-19, we have been actively communicating and cooperating with the World Health Organization and invited the WHO to send international experts twice to conduct joint studies on SARS-CoV-2 origins-tracing in China,' said Shen Hongbing, deputy chief of the national administration of disease prevention and control and director of the Chinese Center for Disease Control and Prevention (China CDC), while explaining China's efforts in this regard.
