BEIJING: An expert mission to China to probe the origins of the Covid-19 pandemic was in disarray Wednesday after Beijing denied entry to the World Health Organization team at the last minute despite months of painstaking negotiations.

Ten experts were due to arrive in China this week for the delicate, highly politicised task of establishing how and where the virus jumped from animals to humans.

But with a number of the team already in transit, China denied them entry visas, prodding WHO chief Tedros Adhanom Ghebreyesus, to say he was “very disappointed”.

China is determined to control the origin story of the virus, which has killed more than 1.8 million people around the world and laid waste to global economies.

The first cases of the coronavirus were recorded in the central Chinese city of Wuhan in late 2019, prompting accusations of chaotic, secretive handling by Chinese authorities which led to its spread beyond China.
