China, the most populous country on Earth, has no community transmission.
I don't know what went wrong in Mongolia, because I haven't been following that country, but China and New Zealand have demonstrated that with a good public health system, elimination is possible and sustainable.
China also didn't have official community transmission in December 2019 yet we were seeing people coming out of airplanes sick constantly, which allowed us to calculate their infection rates, which were then released publicly when they couldn't be hid any longer.
Today there are no flights out of China and we have to trust the same government when they say they have no transmissions.
Need I point to the centuries long history of communist regimes hiding mass deaths?

No, this did not happen. Infection rates weren't calculated until January 2020. Nobody even knew there was anything like SARS spreading in Wuhan until 27 December 2019.
Within 72 hours of the first test result indicating a SARS-like virus, it was all over Chinese social media, and even CCTV reported on the outbreak. And of course, it only took a few weeks afterwards for the hospitals to become overloaded with sick patients.
> Today there are no flights out of China
This is simply untrue. Just to take one example, yesterday alone, there were 9 flights from Shanghai Pudong Airport to LAX.
The situation in China right now is obvious: the virus is gone. Just ask any of your friends/colleagues who live there.
