The 2026 China Radio Conference opened on Sept. 21 in Xiong'an New Area, Hebei. The conference said advanced manufacturing and new industrialization rely on scarce radio spectrum and a secure electromagnetic environment, and called for optimizing spectrum allocation to drive radio-technology innovation and support industry development. It urged building innovation platforms to integrate radio R&D with industrial applications and strengthening the legal, regulatory and standards framework for radio governance. Organizers said authorities will step up radio monitoring and enforcement, including tougher action against illegal frequency use and unauthorized stations, to bolster electromagnetic-space security. China also pledged deeper international cooperation and will host the ITU World Radiocommunication Conference 2027, aiming to influence international spectrum governance.
