It’s really not fair for journalists to pester the WHO about the origin of SARS-CoV-2. The WHO’s is tasked with improving health and healthcare globally, and they’ll be hobbled in that if they lose the cooperation of the Chinese government. The WHO has no power over governments.
The origins dispute isn’t about some random possible lab leak. It is about a very specific US government funded research programme that had been outsourced via New York based Ecohealth Alliance to Wuhan Institute of Virology. Modifying viruses to have precisely the attributes of SARS-CoV-2 is exactly what the US research programme was doing.
The Chinese government can be accused of covering up, but Ecohealth Alliance even more so. It was Ecohealth Alliance that took offline the database of bat coronaviruses closely related to SARS-CoV-2 soon after the pandemic was identified. Ecohealth Alliance should be made to open its records, but they are subject to US courts and law, not Chinese.
So the dispute is between two Permanent Members of the UN Security council ie. nuclear armed superpowers, namely the governments of the USA and China. The ‘news’ media should let the WHO get on with its job and direct their questions to the UNSC instead.
