I'm very suspicious of this article. I've watched a decent bit of the interview, and I'm concerned about the lack of verification that she is in fact a UN employee as she claims, and the absence of any incriminating emails she mentions in the interview.
Interesting, I havevn't followed up on it, but the UN recently did come out to deny these claims in a recent press conference, which didn't deny she was an employee there.
But you're right details are not easy to self-verify; but given what the CCP has done and continue to do with the WHO is it really all that far-fetched to see they paid off a bunch if UN members to pass them information. Consider how the US needed operatives/assets inside the Iranian nuclear program to deploy what eventually would become Stuxnet-gate.
You're right, and that detail about the UN not denying it (but her claims) makes me a lot less skeptical. Either way I'm very skeptical of the Chinese government w/r/t human rights and I appreciate you drawing attention to it.
Quick edit: It just occurred to me to search for other articles by the whistleblower's name. I still don't see any evidence so I am skeptical, but anyone else reading should have the chance to judge for themselves. https://www.express.co.uk/news/world/1292510/un-human-rights... https://www.foxnews.com/world/un-human-rights-office-china-d...
