For the sake of fulfilling the initiative of "China Dream", Xi Jinping proposes the strategic layout of "four comprehensives". Under the strategic guidance of "comprehensively building a moderately prosperous society", and through the impetus of three party support systems, namely "comprehensively deepening the reform, comprehensive rule of law and the overall tightening up of party discipline," Xi tries to achieve the goal of "Two Centuries" on time. For the People's Liberation Army (PLA), the main objectives are to achieve the goal of building up a strong military, deepen the reform on defense and military, promote the strict rule of law for the PLA, and strengthen the Communist Party control over the military. The 2015 National Defense White Paper "China's military strategy" echoes the "four comprehensives" by stressing the resolute safeguard of national interests on sovereignty, security and development, so as to ensure the fulfillment of "China Dream". It will have a great impact on China's national defense and military build-up; therefore it is necessary to pay attention to and monitor its progress.
