从特朗普到拜登：美国北极政策新发展

Abstract:The Trump administration has continuously strengthened the strategic presence of the United States in the Arctic region through the development of Arctic resources and energy，and enhancing Arctic operational capabilities. It is highly vigilant and strictly guarded against China’s participation in Arctic affairs and Sino-Russian Arctic cooperation. After taking office，Biden faced an increasingly complex Arctic political environment and began to adjust the US Arctic policy practices to further enhance the ability to operate in the Arctic. As an important Arctic power，the adjustment of the US Arctic policy will have an important impact on the geopolitical situation and China’s participation in Arctic affairs.
