Goals reached. Deals signed.  Breakthroughs announced. Those at the 6th World Internet Conference (WIC) call it a busy and productive three days, complete with 20 sub-forums. Officials said participants have engaged in wide discussions over hot issues like artificial intelligence (AI), 5G networks as well as open-source processing chips.

With each edition of the WIC come new challenges for succeeding in an ever-expansive digital world, this sixth WIC attracted over 1,500 experts from over 80 countries and regions promising big things in 5G, AI and more.

In the morning, start-up entrepreneurs were fighting for a chance to be the next internet tycoon. It was the grand finale to the "Straight to Wuzhen" global internet competition. Participants pitched their companies to policymakers, investors and the global audience, and the winners have secured an opportunity to put their businesses on the fast track for growth.

The conference has also been a platform for business leaders to brainstorm how to merge internet and tech with global trends, such as China's Belt and Road Initiative.

"We are a platform focused on agricultural products. I hope that internet technologies can be a great enabler of the Belt and Road Initiative. Chinese experience in e-commerce can be promoted across the region, in many countries that lag behind in digital economy. China has high demands for good foreign farming produce, and we need to rely on e-commerce to import more of it," said Liu Chuanjun, CEO of Meicai.

What's more, it's been a bridge to connect international companies who want to expand cooperation with partners in China and beyond. "We already started to talk with China Unicom and we are trying to also engage with the internet companies. What we want to do is [to] build a silk way, a digital silk way with fiber connections from Europe to Asia. We can be a very good partner to Chinese companies in 5G technologies," said Mustafa Ergen, chief technical adviser of Turk Telecom.

The conference also saw the release of 15 scientific and technological achievements from top tech companies.
