Abstract: China's international cooperation in space has made great progress since the reform and opening up, however, it has also derived alot of problems, especially at the level of the administrative system and regulations. The United Nations space treaties and the UN General Assembly resolutions provide basic principles on the international cooperation in space. China also issued some policy provisions and promulgated scattered laws and regulations on international cooperation in space. In order to further regulate and promote China's international cooperation in space, the proposed "Space Activities Act" should provide the relevant contents of international cooperation in the form of a special chapter. It should mainly clarify the basic position of China on international cooperation in space, clarify the administrative system of international cooperation in space, establish inter-ministerial coordination mechanism, formulate medium and long-term planning for international cooperation, co-ordinate management of international cooperation, as well as relax the technical cooperation and import&export control on aerospace products and technologies.
