this is an interesting criticism. I would have characterized the Chinese leadership of having a much more long-term outlook than the vast majority of other countries.
In a way China made a mistake asking for HK back. While it was British they had a convenient boogeyman to point to, now it is part of China, Beijing has nowhere to hide, and the only option they have is to destroy it. This will be a painful process for both Beijing and HK.
In terms of political culture, I don't think either side really understands the other.
