1. The government is really strong and decisive. All the power resides in the government.
2. The country is rich. They have the means to do things fast.
3. The people are afraid of the government. They, therefore, comply with whatever the government tells them.
Or China is hiding the truth behind all their statement. We all know that the Chinese government is well known to manipulate data information that is released globally. It is another reason why WHO failed to address the pandemic as soon as possible since the DATA about the source of the pandemic was hidden by China. It was then well known when a religious group from South Korea were infected that Health Society established a clearer view and knowledge about Covid-19. Aside from that, there is news of a young Chinese journalist that expose the real situation of China was gone missing.
China is hiding a portion of the truth, which makes everything else essentially lies. But that's not happening in China alone. It's just that the hidden portion is much larger in China than in other countries, or so I think. Again, that is brought about by a very strong government. You try to show what is hidden and you will most certainly end up as hidden as those information.
WHO has been around for more than 70 years and I guess the problems, or at least the great majority of those, they were addressing when it came forth are the very same problems that they are addressing now.
