I do not read Chinese fluently, but I do follow news from China pretty closely (I lived in China for a couple of years) and I am not denying that top-members of the party are taking advantage of their position (Wen Jiabao as an example). Although I agree with you that we do not know it for sure due to the lack of transparency, the corruption problem in China is similar to the problem we have in other countries like in Brazil, where I live. And in both countries there always the forces "for" and "against" working to put things under the rug or investigate and prosecute, most of the time for political gain (Bo Xilai as one example, and here in Brazil we have other similar cases too).
In Russia it seems that it's a different problem altogether, that is, a mob were able to literally seize part of the country, including the president's cabinet. In Brazil and in China we can say (sometimes cynically) that all politicians are corrupt, but there are opposite forces at play, but to me it seems like in Russia the damage is really catastrophic. (granted that I do not follow Russian politics, so I am not completely sure)
