A 15-strong French military contingent has arrived in the Greenland capital Nuuk, as several European states send soldiers there as part of a so-called reconnaissance mission.
The deployment, which will also include personnel from Germany, Sweden, Norway and the UK, comes as US President Donald Trump continues to press his claim to the Arctic island, which is a semi-autonomous part of Denmark.
French President Emmanuel Macron said the initial troop deployment would be reinforced in the coming days with "land, air, and sea assets".
Senior French diplomat Olivier Poivre d'Arvor saw the mission as sending a strong political signal: "This is a first exercise... we'll show the US that Nato is present."
The movement of military personnel comes after Denmark and Greenland's foreign ministers travelled to Washington for a meeting with US Vice-President JD Vance on Wednesday.
