BEIJING, March 15 (Xinhua) -- China will introduce a series of regulations and documents in accordance with the foreign investment law to protect the legitimate rights and interests of foreign investors, Premier Li Keqiang said on Friday.

This is an important thing China is to do in the next step to ensure that the law is implemented smoothly, Li said at a press conference after the conclusion of the annual session of China's national legislature.
