BEIJING - China needs policies to support Internet technological research, experts have said.

A symposium on cyber security and informatization attended by top Chinese leaders on Tuesday called on the industry to make progress in core Internet technology and on officials to heed public opinion.

Yao Hongyu, CEO of Yoyo Systems, said China needs to develop core technology in fields such as cloud computing and big data.

Government and military agencies should develop their own products, as this could be vital to information security and the growth of related domestic industries, Yao said.

Tong Liqiang, director of the Beijing cyberspace information office, holds similar views. China need to master core technology in Internet infrastructure, he said.

Shen Yi, deputy director of the Cyberspace Governance Study Center with Fudan University, said governments at all levels need to better understand public opinion on the Internet.

Zhu Wei, an associate professor with China University of Political Science and Law, said that government officials needs to be more tolerant of public criticism and better understand the needs of common citizens.
