Guizhou is home to data centers for China Mobile, China Unicom and China Telecom, the three largest Chinese telecommunication operators. Xi visited China Telecom's cloud computing research park and watched demonstrations of its Internet applications.

In China Telecom's data centers, each room housed nearly 2,000 servers. Xi was told the fourth-generation data centers were completely developed independently and there would be more than 800,000 servers after the construction of the state research park finished.

Although Guizhou is among the least developed regions in China, it has put more efforts developing its big data industry since last year, establishing a state-level big data agglomeration and aiming to contain two million servers. Some cities in Guizhou offer free city-wide WiFi service.
