Wuhan scientist welcomes visit over lab leak claim
A Chinese scientist at the centre of unsubstantiated claims that the coronavirus leaked from her laboratory in the Chinese city of Wuhan has told the BBC she is open to any kind of visit to rule it out. The surprise statement from Prof Shi Zhengli comes as a World Health Organization (WHO) team prepares to travel to Wuhan next month to begin its investigation into the origins of Covid-19.
The remote district of Tongguan, in China s south-western province of Yunnan, is hard to reach at the best of times. But when a BBC team tried to visit recently, it was impossible.
