Britain said on Wednesday that China must cooperate with the World Health Organization review into the origins of the virus which causes COVID-19 so that the world can understand who is responsible.
The United States and Britain have expressed concern over the access given to a WHO mission to China - where the novel coronavirus emerged in late 2019.
"We want to see full cooperation," Foreign Secretary Dominic Raab told BBC radio.
Raab said that the world needed to know detail of the origins of the outbreak "because then the issue of responsibility can be addressed but also frankly, looking forward, so we can learn the lessons."
