Scholars, tech companies and government officials from around the world gather annually in one of the nation's famous historic water towns - Wuzhen - known for its rivers and canals.
Launched in 2014, China's biggest internet forum brings together global stakeholders to discuss issues, such as tech trends, internet governance and the responsible use of technology.
In a congratulatory note sent to the first Wuzhen Summit, President Xi Jinping said he hoped internet specialists could "improve cooperation and build a safe network", and "reach agreements on global network governance".
Who will attend this year's conference?
The World Internet Conference now has more than 170 members from over 30 countries and regions.
Members such as IBM, Cisco, Nokia, Alibaba, and smartphone maker Honor have confirmed their attendance this year.
Ministry-level officials from different countries and regions are also expected to be there.
What to expect in this year's summit?
With a theme of "Embracing a People-centred and AI-for-good Digital Future - Building a Community with a Shared Future in Cyberspace," this year's summit will focus on artificial intelligence and its impact on the economy and humanity.
This year's edition will feature 24 sub-forums on topics such as cybersecurity, digital economy, data governance and the Global Development Initiative.
The summit will see the establishment of a special committee on AI, a think tank cooperation programme, and an international digital training institute.
There will also be a new award to celebrate outstanding achievements in the field of the global internet.
What role does Hong Kong play in the Wuzhen talks?
A number of local tech sector representatives are attending the Wuzhen summit, including IT sector lawmaker Duncan Chiu, who will give a speech about Hong Kong's AI development.
Chiu told RTHK that the SAR could contribute in many ways with ongoing AI projects in universities and startups.
"There are many projects ongoing and in universities, we see there are many teams
working on different application of AI, especially in some vertical sectors, like financial markets and on medical," he said.
"The use of AI for enhancing the research result is also on display in many startup teams in Hong Kong."
He added that the city's unique position allows it to bridge global and mainland data guidelines, potentially becoming a leader in cross-border data convergence.
"We can do some trials [to test] how to deal with these data safely and usefully and comply to global standards, regulations, laws, and also fit with the mainland law. That will become a very important breakthrough in terms of doing these cross-border data examples," Chiu said.
