China supports its enterprises' deeper integration into global innovation networks and broader participation in mutually beneficial international cooperation, the country's top economic regulator said on Friday, stressing that China has never required domestic technology companies to reject foreign investment.

Li Chao, a spokeswoman for the National Development and Reform Commission, made the remarks at a news conference in response to media inquiries over reports concerning foreign investment in China's high-tech sector.

The official emphasized that China remains committed to the policy of opening-up, and that its door will only open wider.

Meanwhile, foreign investment in China should be conducted in accordance with Chinese laws and regulations, and must not undermine the country's national security and interests, Li added.

"We will continue to fully implement the Foreign Investment Law and its supporting regulations, and advance the effective implementation of opening-up measures and policies to stabilize foreign investment," Li said.

She added that the NDRC will further foster a market-oriented, law-based and international business environment, while strengthening risk prevention and control.
