I'm not judging, just want to bring some balance to this "truth" you speak of...
You can disagree with their claims. But that is not the same as arguing that any form of self promotion is bad.
Of course, China is far from perfect. Bad things do happen, I am not denying that. If we are speaking about balance, then I think that in western discourse the balance has tipped too much towards the ‘china is always bad in every aspect’ side, totally ignoring or actively denying the good sides, and ignoring equally bad things that happen in their own places.
Will China meddle when their interests are threatened? Of course, and so will any other country in the world.
If China’s interests conflict with yours, then it is fine to point that out. It is not fine to paint them as the bad guys just because they have conflicting interests. And even then, such issues can be resolved peacefully: China has shown that it is interested in negotiation and being reasonable. You wouldn’t believe how much land China has given up since the 40s as part of negotiation deals with other countries. It is time to stop this cold war mentality where it is us vs the evil commies who are out to conquer the world.
The way the Chinese bureaucracy works is that lower-level local government officials have less experience than higher-level officials. They get promotions based on results. Xi Jinping himself was, during the SARS period, the head of a province, and did very well within containing SARS within that province. It doesn’t surprise me if local Wuhan officials simply weren’t as competent in matters of disease containment than the central government.
The Chinese government is not a monolith. Comparing to 1984-style authoritarianism wouldn’t be entirely accurate either. I think it is best compared to a large corporation.
You seem to be afraid of China exporting its model. Chinese diplomats have repeatedly said that they are not interested in doing that. They say: the Chinese way of international relations is one of mutual respect: we will not impose our system on you and you will not impose your system on us. But if you voluntarily want to learn from us then you are welcome.
