Any case regarding Mainland's top-levelled personal reshuffle would be referred to as "power struggle" by the media here in Taiwan, even the one of anti-corruption case against Zhou Yongkang, a former standing member of CCP  politiburo.  I admit there must be some "power struggle" factors involved for Xi's trying to eliminate Zhou, but wasn't the vitriolic remarks exchanged between Obama and Hilary Clinton in 2008 priliminary a kind of "power struggle", wasn't the KMT infighting between Ma and Wang Jingping anther kind of "power struggle"?  Remember politics is not a "love feast" in which people getting happily together, drinking and eating boisterously; instead, it's a serious matter of life and death. 

So let's concentrate on the anti-corruption only.  Basically, in an enclosed society like Mainland China, any person should behave somewhat like a "caged" animal.  If you are wild and fierce like tigers and lions, you may have a larger space; if you are adorable like giant pandas, you may enjoy a better treatment.  But the prerequisite is you must know what you are and don't act excessively.  Therefore, corruption in Mainland China is fundamentally out of  personal behavior, not a systematic one like the influence peddling between interest groups and legislation in the Western World.  Obviously, it's easier to tackle with the corruption problems in China than in those "advanced" counties.  In Chinese societies, there are cultures of entertainments  and giving presents(reciprocally), and Mainland can make luxurious restaurants and goods in doldurms for anti-corruption purpose, but can Taiwan do the same?  Then you know the diffence.
