特朗普再次推动获取格陵兰的核心动机，被分析人士解读为遏制中国在北极地区取得战略立足点。随着海冰融化，北极航道逐步可通航，尤其是横贯加拿大北岸的西北航道，其潜在贸易与军事价值显著上升。格陵兰位于该航道的东侧入口，美国若控制该地区，可在地缘战略上掌握关键通道，类似其对巴拿马运河安全的关注逻辑。

分析指出，中国虽更关注沿俄罗斯北岸的东北航道，但出于战略冗余和长期布局考虑，也可能寻求在西北航道建立影响力。专家强调，中国在“一带一路”中的经验显示，一旦基础设施和规则体系建立，外部力量将难以逆转其影响。在北极这一“仍在成形”的区域，中国希望在航运架构和治理规则中拥有话语权。格陵兰因港口、机场及民用设施的潜在军事用途而具有放大效应。

安全层面的担忧还包括中俄核潜艇在西北航道活动的可能性，该区域或成为潜射弹道导弹和水下能力的潜在部署点。特朗普在最新国家安全战略中提出“特朗普版门罗主义”，强调防止敌对势力控制西半球关键资产。分析认为，格陵兰成为这一战略的关键测试点：要么由美国直接控制，要么由丹麦与格陵兰在安全事务上明确配合美国，从而消除其在东部北极的战略脆弱性。

Analysts interpret President Donald Trump’s renewed push to acquire Greenland as a strategy to block China from gaining a strategic foothold in the Arctic. As melting ice opens new shipping routes, particularly the Northwest Passage along Canada’s northern coast, the region’s trade and military value is rising. Greenland sits at the eastern gateway to this passage, and U.S. control would allow Washington to dominate a critical chokepoint, mirroring its concerns over the Panama Canal.

While China’s primary Arctic focus has been the Northeast Passage along Russia’s coast, experts argue Beijing is likely to seek alternatives for strategic redundancy. Experience from the Belt and Road Initiative suggests that once infrastructure and governance frameworks are established, Chinese influence becomes difficult to dislodge. In an Arctic still “in the making,” China aims to shape emerging shipping architecture and rules. Greenland’s ports, airports, and civilian facilities amplify its importance due to their potential dual-use military applications.

Security concerns also extend to the possibility of Chinese and Russian nuclear-armed submarines operating in the Northwest Passage, which could serve as launch zones for undersea and ballistic missile capabilities. Trump’s latest National Security Strategy emphasizes preventing hostile control of key assets in the Western Hemisphere under a “Trump Corollary” to the Monroe Doctrine. Analysts view Greenland as a critical test case: either the U.S. must directly control it, or Denmark and Greenland must demonstrably align with U.S. security priorities to mitigate vulnerabilities in the eastern Arctic.
