This is all true...but this may or may not be the relavent aspects of their society to be focusing on. There are also things that China has accomplished that should be the envy of the West, such the lack of religious hostilities in their history. (The conflict in the Middle East would just not happen in Confucian Asia.) It all depends really on which parts you want to see.

Remember that due to China's completely different traditions, they can be incredibly bad marketers of their own culture. The Tiananmen thing you keep bringing up is certainly bad, but keep in mind that the good things they do. Suppose to ward off whatever personal bad karma they got from instigating such an event they decided to save, say, 10,000 people from some kind of preventable death. Such a thing wouldn't necessarily have any publicity at all, and you most likely wouldn't know about it, yet it's fairly plausible that something like that did take place in some at least indirect fashion. Their 'economic miracle' has certainly created much more welfare for the Chinese people, beyond any reasonable expectations for a country in their position, than all their human rights violations could take away...Westerners tend to put these two into different categories, but that may or may not be a valid approach. The object, of course, is to keep the good while discarding the bad...this may or may not be possible.

If you really are interested in learning in Chinese culture, a forum like this might be one of the worst places to start out.
