But U.S. -based experts saw Kim's speech as a clear attempt to divide Seoul from its main ally, Washington, which has led an worldwide campaign to pressure North Korea through sanctions to give up weapons programs aimed at developing nuclear missiles capable of hitting the United States.
The New Year's address is an annual event in the North and is watched closely for indications of the direction and priorities Kim may adopt in the year ahead.
