You keep saying this every few pages, but the WHO absolutely DOES pick political fights. At the start of this outbreak, they excluded Taiwan from their conversations for being a Chinese territory instead of a sovereign nation. They still count them as a territory of China instead of a sovereign territory. That is absolutely a political move. A few years back, they appointed Robert Mugabe as a goodwill ambassador. Seriously. They have a history of political controversies. They are an arm of the UN. While their cause is generally good, it is extremely simple minded to think that they don't play politics.
Well, every international organization is a playground of international politics, and WHO is no exception; that I do agree with.
However, in the case of Taiwan/Republic of China, as you have mentioned, WHO is a specialized agency of UN and has to abide by the international law, including UN resolutions; according to UN resolution 2758, People's Republic of China is the only legitimate representation of China in the UN and the government of Taiwan/Republic of China is not a UN recognized entity. This is not a politic matter per se, but rather a matter of regulatory compliance.
I am not the expert of the One China topic and this is way out of topic for this thread, so I will stop now. What I am trying to say is, WHO is a reputable organization and as an entity with no actual authority over countries around the globe it is doing the best it can. The medical community seems to largely agree with and follow its judgment and decisions at this moment as well.
Anyway, apologies for the digression. I know this is a sensitive topic and I am sorry if anyone feels that the course of discussion is unpleasant.
