GUIYANG — The 2025 China International Big Data Industry Expo became a platform for global enterprises to showcase their latest developments, share experiences and exchange expertise in AI, as well as being a zone for international supply-demand partnerships.

The three-day expo, which ended on Aug 30 in Guiyang, capital of Southwest China's Guizhou province, featured a diverse range of exchanges and activities, and attracted more than 16,000 guests as well as 375 enterprises.

Lars Nagel, CEO of the Germany-based International Data Spaces Association, has increased the frequency of his visits to China over the past two years. He views China as one of the front-runners in data-space strategies, and one of the world's leading countries in pursuing the data economy, Nagel told Xinhua News Agency.

Nagel said he noticed that over the past year, clear rules and policies on data sharing have been in place in China, which has allowed enterprises to understand what they can do in terms of cross-border data sharing.

The association is currently running data-space pilot projects between China and Germany, and they are working "pretty well", he said.

"China is a big market with a lot of global, powerful players. And what is even more remarkable is that the Chinese data strategy is really a comprehensive one. It's like a lighthouse in global data strategies to embrace data as a production factor and make use of data for society and for business at the same time," he said.

Nagel's association has a network of more than 180 companies from all over the world. He looks forward to working with the province closely, and to figuring out how to connect data and generate value out of it.
