China has issued a sharp warning to U.S. President Donald Trump over comments and signals related to Greenland, cautioning against actions that could undermine sovereignty, regional stability, and the existing international order. Beijing stressed that Arctic affairs should not become a stage for great-power coercion, as tensions rise over strategic influence, security, and resources in the polar region. The remarks underscore China’s growing concern over U.S. moves in the Arctic and the broader geopolitical contest unfolding beyond Europe and Asia.
