Foreign enterprises are welcome to participate in China's Internet Plus plan, Premier Li Keqiang said Wednesday, vowing to open the sector wider.

He made the remarks when meeting with world business leaders during the Annual Meeting of the New Champions 2017, also called Summer Davos, in the northeastern coastal city of Dalian.

China has opened many businesses and services to foreign investors in basic and value-added telecommunications, the highest level of opening up among developing countries, said the premier.

Foreign investors have huge space for development in Internet Plus, including cloud platforms, telecommunications and cross-border electronic commerce, said Li.

The central government will ensure inclusive and cautious supervision and regulation to help foreign enterprises and to boost Chinese economic growth, said Li.

Joint efforts are needed to address Internet fraud, counterfeits sold online and the theft of commercial secrets, according to Li.

From Tuesday to Thursday, around 1,500 politicians, officials, entrepreneurs, scholars and media representatives from over 90 countries and regions will discuss topics from inclusive growth to the new industrial revolution at the summer forum.
