On July 23, the 2026 APEC Digital and Artificial Intelligence Ministerial Meeting was held in Chengdu. The meeting chair, Minister of Industry and Information Technology Li Lecheng, announced the successful adoption of the Chengdu Statement, formally titled the '2026 APEC Digital and AI Ministerial Statement,' which establishes an action framework for deepening APEC cooperation in digital and AI fields in the coming period. The meeting focused on the theme 'Digital and AI Technologies Empowering the Asia-Pacific Community,' with discussions centered on three topics: strengthening the enabling role of digital and AI technologies in development, promoting universal and meaningful digital connectivity, and supporting digital inclusion and digital skills upgrading. Key outcomes include five highlights: building consensus on innovation driven by digital and AI empowerment, deepening understanding of risk prevention for security and controllability, and establishing goals of inclusive and shared benefits. Notably, this ministerial meeting elevated 'open source' to the APEC ministerial-level cooperation for the first time, encouraging economies to support open-source practices and actively participate in international AI open-source community collaboration. For the metal 3D printing industry, this consensus on open-source cooperation helps lower the barrier to advanced manufacturing technologies, fostering the integrated innovation of additive manufacturing processes and AI.
