The study of military doctrine is one tool that scholars can use to understand a rising power's potential for involvement in interstate war. In its evolving joint operational doctrine, China pursues a defensive approach to securing its land borders and maintaining territorial integrity. Despite the prominence of a Taiwan conflict in China's defense planning, frontier defense remains a core mission for China's armed forces, involving almost half of the PLA's ground forces. China's force structure is consistent with a defensive border itself while most maneuver units capable of offensive operations are based hundreds of kilometers away in the interior. Due to the potential for ethnic unrest in the frontiers, which places a premium on cooperation with neighboring states, China's defensive posture on the Asian continent is likely to endure.
