The contributions contained herein address the role of the Chinese military in shaping its country's security environment. Of course, the PLA itself is shaped and molded by both domestic and foreign influences. In the first decade of the 21st century, the PLA is not a central actor in China's foreign policy the way it was just a few decades ago. Nevertheless, the significance of the PLA must be understood. The military remains a player that seeks to play a role and influence China's policy towards such countries and regions as the United States, Japan, the Koreas, Southeast Asia, South Asia, and of course, Taiwan. It is important not to overlook that, in times of crisis or conflict, the role and influence of the PLA rise significantly.
