Chinese security companies are facing new regulatory complexities when they go global. They need to learn from international experience and clarify the text content and main international standards such as the Montreux document，the International Code of Conduct for Private Security Service Providers. The current international standards mainly emphasize the principles of human rights and international humanitarian law，risk management，especially the impact of human rights risks，the principle and applicability of the use of force，accident management and internal and external reports and Grievance Mechanisms. In the process of regulating overseas security services by Chinese private security companies，it is necessary to face up to the differences in security discourse between China and the west，the differences in security industry between China and the west，and fully understand the main aspects of China’s overseas security context. The current market of overseas security service lies in the supply of professional services in “complex environment”，and the core obstacle of China’s overseas security industry development is to solve the demand for “international and comprehensive” talents. As for good governance，China’s overseas security service regulation needs to be transferred from the government-centered mode to the international “multi-stakeholders governance” mode，and the main actor and player of China’s overseas security service industry mainly utilize the identity as “private security companies”.
