Sorry but this is just hopelessly naive. Have you seen their handling of Taiwan, their statements parroting CCP propaganda in January claiming the virus was not transmissible between humans, their condemnation of travel restrictions as xenophobic? I could go on.....
All international organizations have the same handling of Taiwan. It's not a WHO specific issue, it extends to basically every other similar intergovernmental organization you can think of, even the ones that aren't specialized agencies of the UN (which the WHO is), like INTERPOL.
