It doesn't take much imagination. The head of the WHO does not recommend banning travel to/from China and constantly praises China's actions regarding this virus. Meanwhile, China arrested the very doctors who attempted to alert the public about the virus, and is effectively using quarantine within its own borders to stop its spread. So it makes no sense for the WHO to complain, on behalf of China, about travel bans, when China is implementing a massive travel ban on itself internally.
