China and Russia have conducted their first joint on-site sea ice survey in the Arctic Ocean aboard the Xuelong 2 research icebreaker, marking a new phase of polar cooperation as international competition intensifies over northern shipping routes and resources. According to a report by state broadcaster CCTV, two researchers from Russia’s Arctic and Antarctic Research Institute joined the vessel for the mission, which is part of China’s broader Arctic scientific operations.
Joint Sea Ice Survey Aboard the Xuelong 2
During the expedition, researchers aboard the Xuelong 2 visually observed ice conditions along the ship’s route, recording concentration, thickness, and types of sea ice, alongside snow cover, atmospheric factors, and large animal sightings. According to Lin Long, captain of the Xuelong 2 sea ice team, the joint observation proved more practical than previous voyages. Evgeniy Kozlovskiy, a lead engineer at the Russian institute, stated via CCTV that taking part in the mission allowed the team to learn from China’s sea ice observation methods and experience. These observations aim to complement satellite remote sensing and improve climate change models.
Did you know? China’s ongoing Arctic efforts include multiple simultaneous missions, such as a separate multidisciplinary expedition aboard the research vessel Akademik M.A. Lavrentyev that launched from Vladivostok in August to study marine environments in the Chukchi Sea, East Siberian Sea, and along major regional ridges.
Expanding Sino-Russian Maritime Operations
Scientific collaboration forms just one pillar of a rapidly expanding relationship between Beijing and Moscow in the polar region. According to a report, China’s Arctic footprint includes multiple vessels deployed simultaneously, such as the icebreakers Xuelong, Xuelong 2, and Jidi, alongside the deep-sea research vessel Tansuo-3. Last year’s missions featured extensive submersible operations, including the Fendouzhe submersible reaching depths of 5,277 meters at the Gakkel Ridge. Beyond research, bilateral cooperation extends to operational patrols; in September 2024, Chinese Coast Guard ships and Russian Border Guard vessels conducted a joint patrol in the Bering Sea, observed by the U.S. Coast Guard.
U.S. Security Scrutiny and Legislative Response
Washington has increasingly viewed these joint activities through a national-security lens. U.S. officials have expressed concern regarding the potential dual-use applications of Chinese research vessels operating near Alaska and other strategic polar waters. In response to these developments, U.S. senators introduced legislation earlier this summer designed to require foreign government research vessels to secure formal authorization before conducting marine scientific research within or near the U.S. Exclusive Zone. The heightened monitoring reflects broader geopolitical tensions over economic opportunities and maritime security in a rapidly warming Arctic.
