The icebreaker 'Xuelong' made the Arctic Ocean passage from China through to Norwegian waters. The Chinese icebreaker completed the Arctic North-East Passage marking the first such voyage by a Chinese vessel and opening an Arctic route connecting the Pacific and the Atlantic for future Chinese science expeditions. In completing the voyage, the icebreaker Xuelong or Snow Dragon channeled through five marginal seas of the Arctic Ocean: the Chukchi Sea, the East Siberian Sea, the Laptev Sea, the Kaka Sea and the Barents Sea.
