China plans sixth Antarctic research station, sparking geopolitical concerns

China announced plans to build its sixth Antarctic research station in the little-studied Marie Byrd Land, with construction slated for next year and operation limited to the summer season. The move has prompted Australian senator Jacqui Lambie and scholars such as Jiliang Chen and Elizabeth Buchanan to question whether the project is driven by scientific goals or a bid for greater strategic influence. Although the Antarctic Treaty prohibits new military bases, the dual-use nature of satellite, communication and drone technology raises concerns about possible future militarisation.

China’s expanding presence in the Commission for the Conservation of Antarctic Marine Living Resources, especially its interest in krill fisheries, adds another layer of geopolitical friction. Critics also point to China’s broader “Polar Silk Road” ambitions, including a forthcoming nuclear-powered icebreaker, which could reduce reliance on ports like Hobart. While some observers, like former Australian Antarctic Division head Tony Press, view the summer-only station as largely symbolic, they agree that the growing physical footprint may shape future treaty decisions.
