Security assistance aims to improve the security governance capabilities of partner countries through operation supporting, capability building, equipment and technical assistance, and logistical support. Western countries conceal their geopolitical concerns in their security assistance by two different logics. One is to bring the emerging civil support into security assistance so as to dilute its geopolitical concerns, and the other is to fully include conflict management, stabilization and peacetime so as to highlight the public goods attribute of security assistance. However, such measures are difficult to be effective. On the one hand, traditional military assistance dominates Western security assistance. On the other hand, existing Western security assistance insists on monopolized provision and refuses cooperation based on the division of labor. Thus far Western practices of security assistance often export liberal peace theory, induce supply competition, and make more trouble for partner countries. Based on developmental peace theory, the Global Security Initiative proposed by China aims to promote the division of labor and cooperation of security assistance and enduring peace in partner countries, which could contribute to re-establishing the public goods attribute of security assistance.
