U.S. President Donald Trump has been actively discussing the potential purchase of Greenland with his national security team, the White House said Wednesday, stressing diplomacy remains his preferred course while other options are not ruled out.

"That's something that's currently being actively discussed by the president and his national security team," Press Secretary Karoline Leavitt said when asked about a possible U.S. offer to buy the territory from Denmark.

"His team is currently talking about what a potential purchase would look like."

Leavitt reiterated that Trump believes acquiring Greenland would be in the interest of U.S. national security.

"He views it in the best interest of the United States to deter Russian and Chinese aggression in the Arctic region. And so that's why his team is currently talking about what a potential purchase would look like."
