DAVOS, Switzerland, Jan 22 - The framework deal on Greenland agreed with U.S. President Donald Trump would require NATO allies to step up on Arctic security and the first results of this will be seen this year, NATO Secretary General Mark Rutte told Reuters on Thursday.

It was now up to NATO commanders to work through the details of extra security requirements, Rutte said in an interview at the World Economic Forum's (WEF) annual meeting in Davos, Switzerland, adding that he was sure non-Arctic NATO allies would want to contribute to the effort.
