Article 35 of the Foreign Investment Law provides for the "security review of foreign investments that affect or may affect national security". On 18 January 2021, the Order No.37 of 2020, “Measures for the Security Review of Foreign Investment” entered into force. The Order establishes a new body dedicated to national security reviews (the NSR Office) jointly headed by the NDRC and the Ministry of Commerce. The new framework establishes both a sector-specific mandatory review for all foreign investments in the defense industry or related sector irrespective of value, and a mandatory review mechanism for certain acquisitions in specified sectors that include "important agricultural products, important energy and resources, critical equipment manufacturing, important infrastructure, important transportation services, important cultural products and services, important information technology and Internet products and services, important financial services, key technology, or any other important field related to national security".
On 1 September 2021, review requirements for operations involving companies headquartered in or having branches in China as well as local companies engaging with foreign investors changed: If these operations imply a transfer of “important data” overseas, the transaction is henceforth subject to a security assessment by the Cyberspace Administration of China. The change results from the entry into force of China’s Data Security Law on 1 September 2021. Among others, the Law establishes a classification system of different types of data in relation to their national security sensitivity. The classification makes some of these data fall under the scope of China’s Cybersecurity Law., with the described consequences for their transfer abroad in the context of international investment. This Law applies to both foreigners and nationals of China. 
Previously in 2018, the State Council in China had already implemented 'Working Measures for Outbound Transfers of Intellectual Property Rights (for Trial Implementation)', which conditioned the outbound transfer of certain kinds of intellectual property rights to a specific examination regime. The examination applied to the transfers of IPRs occuring in the context of exporting technologies, or in foreign investors’ acquisitions of domestic enterprises. The examination focused on the transfer’s impact on China’s national safety and capacity for the creation and development of key technologies in important industries.
