The Arctic reveals some characteristics of classical geopolitics and the overall trend in critical geopolitics, which emphasizes international cooperation. However, after Donald Trump became the president of the United States, variables emerged in the Arctic, leading the United States toward the direction of classical geopolitics. The Trump administration's national security strategy has turned to great power competition and emphasized the principle of "America First." Therefore, the U.S. Arctic strategy has shifted from international cooperation to great power competition. Since the United States regards China as its biggest strategic competitor and security challenger in the future, the two countries may engage in competition and conflict in the Arctic. Yet this does not hinder cooperation between the two countries in the Arctic. In addition to the existing cooperation between the two countries, there is room for cooperation in many fields.
