It's unfortunate that the CCP feels the need to commit such atrocities to preserve their rule and stability over the region. A more appropriate government for one with such cultural and regional diversity as China would be a federated one where minorities and ethnically distinct regions see representation at the highest levels of government, and this representation should lead to stronger rule and stability without the need for such violence. Furthermore, doing so should strongly dampen the nationalist desires of these regions. But of course, the CCP is ideologically opposed to self-representation.
