Rules for foreign investment security reviews will not add unnecessary burdens to normal foreign investors and enterprises, but are conducive to the development of foreign-funded businesses in China in the long term, according to the Ministry of Commerce (MOC) on Thursday.

The rules fine-tune China's foreign investment security review system in accordance with the requirements of the foreign investment law and relevant regulations, MOC spokesperson Gao Feng told a regular press conference.

Gao said that the rules are a necessary guarantee for the stable and healthy development of China's economy and further opening-up to the outside world.

Under the rules, foreign investment in the military industry and relevant sectors pertaining to national security, as well as in surrounding areas of military infrastructure, shall be reviewed, Gao said.

Foreign investment in nine sectors concerning national security, including vital agricultural products, energy and resources, shall also be reviewed when foreign investors have control over the enterprises they invest in, he further explained.

Conducting security reviews on foreign investments is a regular international practice, Gao said.

Chinese authorities released rules for foreign investment security reviews at the end of last year. The rules came into effect in January.
