Cloud based technologies, especially business-to-business (B2B) livestreaming, helped establish communications among thousands of enterprises at the seventh China-Eurasia Expo.

The four-day expo, officially launched in Urumqi, capital of northwest China's Xinjiang Uygur Autonomous Region on Monday, attracted 3,600 enterprises from 32 countries and regions to attend its online events, displaying nearly 17,000 exhibits, including food, machineries, materials, and technologies in the fields of energy, commodity, finance and many others.

More than 70 companies will try B2B livestreaming during the expo, with the first three streams launching at 11:00 a.m. Beijing Time (0300 GMT) on Tuesday.

The expo will be held both online and offline. Covering an area of 40,000 square meters, the expo's offline event has set up three zones featuring themes including investment cooperation and commodity trade.

For the first time, "Tianshan Forum" panel discussions will be held alongside the expo, where guests will discuss topics including Belt and Road, international sci-tech cooperation, finance development and health.
