This volume provides unique insights into the PLA's achievements over the span of Hu Jintao's tenure as Central Military Commission Chair from 2002 to 2012. This period saw a remarkable growth in capabilities and a critical expansion in the military's missions. The PLA increased its adoption of information technologies and advanced sensors into its modernization efforts. It also improved its ability to carry out joint training and missions other than war. Reflecting developments in the Chinese Communist Party, the PLA also experienced important changes in its political focus and mission. Most significantly, Hu Jintao introduced the "historic missions," which oriented the PLA toward a much greater international mission than it had previously undertaken. Supporting this new international mission, the PLA expanded its participation in international military exercises, as well as peacekeeping operations and humanitarian assistance and disaster relief missions abroad, including its first ever permanent naval deployment abroad in the counterpiracy missions in the Gulf of Aden. Understanding how the PLA matured and developed in the Hu era is critical to understanding the PLA today, and for identifying opportunities to further cooperation between our two militaries.
