As global warming and sea-level rise continue，the international community is increasingly willing to participate inarctic governance. However，the crisis in Ukraine has affected the security and stability of the arctic region，and the Arctic Council has been stalled，resulting in the formation of a “seven against one” confrontation among arctic countries，which has posed a huge challenge to arctic regional governance. As a low-sensitivity field，science diplomacy is a preferred way for arctic countries to realize sustainable development in the arctic and restart arctic cooperation. Arctic countries’ arctic science diplomacy mainly focuses on three aspects，namely，scientific infrastructure，scientific education cooperation，and scientific cooperation in specific fields. Due to the complex geopolitical environment in the arctic，the progress of some specific cooperation projects has been slow，some scientific cooperation has even been interrupted，and there is a lack of trust between arctic countries in scientific cooperation，which hinders scientific diplomacy. As a geographically near-arctic country，it is necessary for China to sort out the latest developments in arctic countries’ science diplomacy and grasp the frontiers of scientific research in the arctic region，so as to formulate a diplomacy strategy in line with China’s national conditions for the future development of arctic science diplomacy and participation in arctic governance.
