Donald Trump has appointed Jeff Landry, Republican governor of Louisiana, as the US special envoy to Greenland. Landry called it an "honour to serve in a volunteer position to make Greenland a part of the US" on X. This move sparked a fresh diplomatic row with Denmark, which governs Greenland. Greenland's prime minister responded, saying the island must "decide our own future" and that its "territorial integrity must be respected." The appointment comes amid rising strategic competition in the Arctic. Melting ice is opening new shipping routes and increasing access to valuable mineral resources. This highlights growing international interest and tension over the Arctic's future.
