They’ll never tell the truth, and the WHO has always taken care to flatter and fawn over the Chinese regime since this started, so that’s that.
They flatter and fawn over every government.
They didn't even criticise Trump when he defunded them, they just wished him well and looked forward to continuing good working relationships with US scientists.
Likewise they have never criticised Bolsonaro even though they can be in no doubt that he is dangerously insane, instead they just praise the state level government of Brazil and the hardworking health workers and scientists on the ground.
Likewise they have never criticised Putin, even when directly asked what they had to say about Russia hiding their true death rates, instead they just explained the benefits, for all countries, of keeping accurate data.
I think what a lot of people don't get is that WHO doesn't have any real power. If they piss a country off, that country can just say 'fuck you' and stop co-operating and there's nothing WHO can do about it. They can't force their way in anywhere, they don't have an army, they don't have the power to impose sanctions. All they have is diplomacy.
They know China is secretive and has a history of covering up disease outbreaks. They also know they wouldn't stand a snowflake's chance in hell of getting into China to investigate, even to the small extent that China has permitted, or of getting China to share any information with them, if they were not unfailingly polite and diplomatic. Even so, it took months and months before they were permitted access.
This article is quite old now but it's very useful background for anyone trying to understand why WHO operate in the way that they do:
