North Korea accused its neighbor, the South, of deliberately sabotaging planned high-level talks with "arrogant obstructions", warning that prospects for any future dialogue had been severely damaged.

The two Koreas had initially agreed to hold their first high-level talks in six years in Seoul on Wednesday and Thursday this week, but they were called off at the last minute following a dispute over protocol.

"The South side had no intent to hold dialogue from the beginning," said a spokesman for the North's Committee for the Peaceful Reunification of Korea (CPRK) -- the state body that handles inter-Korean issues.

"It only sought to create an obstacle to the talks, delay and then torpedo them," he said in a statement carried by the official Korean Central News Agency, accusing the South of "arrogant obstructions and deliberate disturbance".

"This impolite and immoral provocative behavior made us think once again whether it will be possible to properly discuss matters or improve relations even if official talks are opened in the future," the spokesman said.

The agreement to meet in Seoul this week had looked vulnerable from the outset -- requiring 17 hours of negotiation on Sunday that ended with no real consensus on the agenda and other issues.

The final nail in the coffin was a dispute over who would represent each side, with the North arguing that the South's nomination of a vice minister as its chief delegate was an insult.

When Seoul refused to upgrade to a cabinet minister, the North cancelled the dispatch of its delegation.

The South's Unification Ministry, which insisted its vice minister was commensurate in rank to the North's chief delegate, said the CPRK spokesman's take on the talks' collapse was "distorted".
