China outlines its specific foreign investment objectives primarily through its Catalogue for the Guidance of Foreign Investment in Industries, most recently revised in March 2015, and maintained by MOFCOM and the National Development and Reform Commission (NDRC). The catalogue delineates sectors of the economy where foreign investment is "encouraged," "restricted," and "prohibited." Investment in sectors not listed in the catalogue is considered permitted. China "encourages" investment in sectors where it believes it will benefit from foreign assistance or technology. Investment is "restricted" and "prohibited" in sectors that China deems sensitive, that touch on national security, or which do not meet the goals of China's economic development plans.
