Abstract：To promote building the “Polar Silk Road”, close attention should be paid to the Arctic strategy of America. The Arctic is a significant region of the US's global strategy, and also the historic extension of China's Belt and Road Initiative, gathering sustainable delivery of strategic resources from both countries. In the context of the escalating structural contradictions between China and the US, the Trump administration's Arctic strategy is committed to enhancing America's competitive advantage in the Arctic, safeguarding America's Arctic interests, restricting non-Arctic countries's participation in Arctic affairs, and ultimately building the so-called strategic encirclement of China from Indian Ocean to the Arctic Ocean. The hindering mentality characterized by competition and containment shapes the inevitable decision of the current US government to cope with the “Polar Silk Road”. However, due to economic and strategic resources constraints, the US chose to prevent China to participate in the Arctic affairs with allies, and the corresponding policy construction has brought instability to the “Polar Silk Road”. The Arctic geopolitical and economic pattern is likely to witness such a prospect that the “Polar Silk Road” based on the northeast route, which is led by China and Russia, would coexist with the “North American Arctic Corridor” based on the northwest route, which is led by America and Canada.
