Chinese President Xi Jinping sent a congratulatory letter to the China International Big Data Industry Expo 2019, which opened in the city of Guiyang, southwest China's Guizhou Province, on Sunday.

"The new generation of information technology, represented by the Internet, big data and artificial intelligence, is booming at present and has significant and profound impacts on the economic development, social progress and people's lives of all countries," Xi said.

Different countries need to strengthen cooperation, deepen exchanges, grasp the opportunities of digital, internet-based and intelligent development, and properly address the legal, security and governance challenges in the development of the big data industry, he said.

China attaches great importance to the development of the big data industry, and is willing to share opportunities of the digital economy's development with other countries and jointly explore new growth drivers and development paths by exploring new technologies, new business forms and new models, Xi said.

Xi added that he hopes delegates and guests at the expo discuss plans for the industry's development and cooperation in the field to contribute to the common development of all countries and the building of a community with a shared future for humanity.
