WASHINGTON (Reuters) - The White House said on Sunday that the United States is open to talks with North Korea, but said Pyongyang must comply with United Nations Security Council resolutions and ultimately agree to denuclearisation.

"We have always favored dialogue and, in fact, have open lines of communication with the DPRK," said Ms Caitlin Hayden, spokesman for the National Security Council.

North Korea on Sunday proposed high-level talks with the US to ease tensions on the Korean Peninsula, a week after it scrapped the first official talks with South Korea in over two years.
