The Communist Party leadership has repeated its call for the establishment of "cyberspace sovereignty" and for developing nations to assume a greater role in governing the internet at the global level.
But the appeal came as the mainland was ranked at the bottom of an index measuring internet freedom compiled by an independent watchdog.
China would "uphold cyberspace sovereignty" and make the governance of the global web "more fair and equitable", President Xi Jinping said in video remarks played at the opening of the third World Internet Conference in Wuzhen, Zhejiang province.
Xi had voiced the idea of internet sovereignty at the annual summit last year, an unambiguous announcement that Beijing would intensify its censorship and control of the internet.
As Xi left for Peru where the Asia-Pacific Economic Cooperation forum is holding its summit, Liu Yunshan, the No 5 in the Politburo Standing Committee who leads ideological control, addressed the audience of about 1,600 people.
"Global cyberspace governance is at a crucial crossroads," Liu said. "Emerging markets and developing countries should have a bigger say. No internet hegemony should be allowed. Nor should the governance be led by one or some parties," he said.
