I want to know the answer to the following question:
Members of which committee attended the conference?
All the background I'm provided with is that "The conference was attended by General secretary Hu Jintao, Wu Bangguo, Wen Jiabao, Jia Qinglin, Li Changchun, Xi Jinping, Li Keqiang, He Guoqiang and Zhou Yongkang, all members of CPC Politburo Standing Committee signaling the commitment of senior Chinese leaders to development of Tibet and ethnic Tibetan areas.". Is that enough to answer the question?
