(AP) — Trump declined to name a reasonable price for the United States to buy Greenland during a meeting in Davos with the NATO secretary general.

“There’s a bigger price, and that’s the price of safety and security and national security and international security having to do with many of your countries,” Trump responded when asked by The Associated Press how he would calculate a reasonable offer for the strategic land mass. “That’s really the price. It’s a big price.”

Trump responded ambiguously when asked to elaborate on his earlier comment that “we will remember” if Denmark refuses to sell Greenland to the U.S.

“You’ll have to figure that out for yourself,” he told a reporter.
