The majority of WHO controversies are made up, the WHO are not a political entity so they do not want to comment at all on political issues; and whatever you want to say about Taiwan it is a very heated political situation.

That's also the evidence of "alignment with china": because we in the west see a failure to recognise taiwan as siding with china. Which is odd because the USA doesn't officially recognise Taiwan itself. In fact the WHO did almost exactly what a US diplomat would have done- albeit a bit delayed.

Corruption not withstanding (yeah, it's unfortunate but that thing is going to happen, what matters is the response not that it happened) it's better to have a bipartisan global concerted effort to manage these things than the centralised health organisation of a single country. Even though that country is the homestead of the service in question.
