With the deepening reform of foreign investment management system and the development of national security regime in China，the national security review system for foreign investment has emerged gradually. On December 19，2020，the National Development and Reform Commission and the Ministry of Commerce jointly issued The Measures for the Security Review of Foreign Investment，which established a unified institutional framework for the national security review of foreign investment in China. The framework leaves much room to be improved，with many provisions of The Measures for the Security Review of Foreign Investment need to be refined and clarified. At present，the main problems include the low level of legislation，the vagueness of the review body，the low transparency and the insufficient protection of the parties’ procedural rights. It is recommended to elevate the level of legislation，improve the operational mechanism of the review body，increase the transparency of the review system and optimize the procedural rules，so as to further improve the national security review system for foreign investment in China.
