It’s become conventional wisdom that China secretly controls the WHO, the evidence for which is that (1) the WHO hasn’t criticized China, which is not really something the WHO does, (2) “funding.” In reality, China is a minor funder, ranked 16th behind Kuwait & Rotary Intl
The other big piece of evidence that “China controls the WHO” is that the WHO follows the rules set by its member states, and observed by nearly every IGO, in not recognizing an independent Taiwan. Which is also the US position!
There is a big divide on my timeline between people who are familiar with how IGOs operate and people who think the video of Bruce Aylward dodging questions about Taiwan is proof of a vast China-WHO conspiracy.
