杨尚昆
When President Yang Shangkun asserted his reserve powers from his membership in the Central Military Commission and openly split with general secretary Zhao Ziyang over the use of force, to side with Premier Li Peng and Central Military Commission chairman Deng Xiaoping, the official policy became inconsistent and incoherent, significantly impeding the exercise of power. By 1993, General Secretary, Central Military Commission chairman, and President were consolidated into the same person, a practice that has been continued since.
