Members of TC609, experts from relevant industries, representatives of standardization organizations, and officials from the national data system also participated in the event.

  1. Keynote Speech

Mr. Liu Liehong noted that since the establishment of TC609, China’s data standardization system has continued to improve, the development of data standards has accelerated, the scope of pilot verification has expanded, and international cooperation on data-related standards has deepened. All of these are aligned with the central task of advancing the market-oriented allocation reform of data as a production factor.

Data issued by the National Data Administration and the State Administration for Market Regulation, revealed that China developed and released more than 120 national standards in the data field during the 14th Five-Year Plan. These national standards have been applied in key areas such as artificial intelligence applications, new infrastructure, and data trading and circulation, supporting the high-quality development of the digital economy.

Mr. Liu emphasized, moving forward, TC609 should work on four priorities:

  1. Improving multi-level mechanisms for data standardization, promoting an effective model where unified national rules are supplemented by industry-specific and local characteristics.
  2. Optimizing data standards supply through diverse channels, with priority support for innovation-driven private enterprises with strong R&D capacities and core technologies to take the lead in standards development, transforming advanced business practices and industrial experience into national standards.
  3. Strengthening multi-dimensional verification and implementation of data standards, cultivating third-party evaluation service providers and making full use of testing, inspection, and certification mechanisms.
  4. Deepening international cooperation on data standards from multiple angles, enhancing talent development in international standardization and continually advancing the transformation of domestic technical standards into international standards.

Additionally, keynote speeches were delivered by Mr. Chen Jun, Director of the Moganshan Geospatial Information Laboratory and Professor at the National Geomatics Center of China; Mr. Yu Haibin, Researcher at the Shenyang Institute of Automation at Chinese Academy of Sciences; Mr. Ye Zhenzhen, Chairwoman of People’s Daily and Director of the State Key Laboratory of Communication Content Cognition; Mr. Sun Baolin, Director of the China Copyright Protection Center; Jarosław Kowalski, Chief Expert of CEN/CENELEC JTC 25; and Raymond Forbes, Vice Chairman of ETSI TC DATA.
