Under the ITU Radio Regulations framework the parties negotiated more than 30 items across multiple high- and low‑Earth orbit systems, covering fixed and mobile satellite services in L, S, C, X, Ku, Ka and Q/V bands. The sides exchanged views, reached multiple consensuses and signed meeting minutes.

The Chinese delegation included MIIT’s Radio Management Bureau, the National Radio Spectrum Management Center, Beijing Tracking and Communication Technology Research Institute, China Satellite Network Group, China Satcom Group, Shanghai Yuanxin Satellite Technology and Tsinghua University. The Norwegian delegation included the Norwegian Communications Authority, Space Norway and SpaceX Norway.
