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.
Correction: not arrest. They were summoned and given written warnings. China is quarantine one Province. Travel between other provinces are still not affected. International travel bans is basically as strict as traveling out of Hubei province, stricter than average travel restrictions in China.
That's an arrest. Arrest does not mean you go to jail. You're taken in for questioning for up to 24-48 hours at which point you must be further charged or released.

The Chinese government censured doctors who sounded the alarm, and you want other countries to follow their advice? I'd say exercising more caution than China advises is appropriate given how little we know about this disease.
