By bootlicking China, WHO is just expensing her own credibility. Many no longer follow the authority of WHO. For example, many countries started restricting travel from China[0] to give themselves more time to prepare when WHO opposed it[1]. Experts had long questioned WHO's decision to refuse to declare it a pandemic[2], before WHO's late announcement yesterday.
There are some efforts to stop the ripple of this China political power play, particularly by Taiwanese and Hong Kongers[3]. We should all be more alert.
