China urged the US to stop politicising the research for the origins of the Covid-19 pandemic, and to invite the WHO to investigate Fort Detrick and the University of North Carolina on the basis of "reciprocity". The Director-General of the Arms Control Department of the Ministry of Foreign Affairs, Fu Cong, said that if the US accepts an origin-tracing investigation in their labs, then China would accept similar visits. A classified US intelligence report delivered to the White House on Tuesday was inconclusive on the origins of the Covid-19 pandemic, in part due to a lack of information from China, according to US media reports.
