Abstract: Gas hydrates in the polar regions exist in sediments or sedimentary rocks on the continents and in adjacent offshore areas. The distribution of gas hydrates is closely related to the permafrost area. The potential of the gas hydrate resource in the polar regions is very large. Gas hydrate occurs mainly in sand-rich reservoirs, which provide the high permeability required for a mass accumulation of gas hydrates. With global warming, accelerated melting of sea ice and opening of waterways in the Arctic Ocean will facilitate the exploration and exploitation of the rich resources in these areas. However, there is the potential for dispute among countries wishing to exploit this resource. This paper reviewed the status of polar gas hydrate exploration and the development of relevant national policies. Based on the current status of gas hydrate exploration and development in China, we present ideas and suggest ways of participating in polar gas hydrate research and development to provide a reference for China’s polar resource development and utilization strategy.
