(CNN) The working-level talks between the United States and North Korea in Stockholm, Sweden, have concluded for the time being, US and North Korean officials said Saturday.

Painting different pictures of the meeting, US officials said they "had good discussion" while North Korea's top negotiator blamed the ended talks on Washington.

"The break-up of the negotiation without any outcome is totally due to the fact that the US would not give up their old viewpoint and attitude," Kim Myong Gil, North Korea's top negotiator, said.
