The Democratic People's Republic of Korea (DPRK) accused South Korean authorities Thursday of leaking the minutes of the 2007 north-south summit, the official KCNA news agency reported.

"The group (South Korea's conservative ruling party) ... has no face to talk about trust as it is unhesitatingly using even the minutes of the inter-Korea summit as a political plaything to meet its partisan interests," a spokesman for the Committee for the Peaceful Reunification of Korea said in a statement.

The summit minutes should be handled as top secret and strictly kept, said the unnamed spokesman, claiming "Chongwadae was behind the action."

The spokesman said "the present conservative group, in a bid to calm down public uproar, had once again taken issue with the remarks made by former president Roh Moo Hyun, by revealing the summit minutes to the public."

According to the revealed 2007 inter-Korea summit minutes, Roh called for giving up the Northern Limit Line (NLL) in the West Sea.

The summit adopted the historic Oct. 4 declaration, which "clarifies a reasonable way of peacefully settling the issue of the maritime demarcation line in the West Sea ... Had it been sincerely implemented, it would not have posed any problem," the statement said.

The NLL, which the DPRK refuses to acknowledge, was drawn unilaterally by the U.S.-led UN Command at the end of the 1950-53 Korean War.

Since the minutes of the summit had been abused for sinister political purposes, "who can believe in the sincerity of another summit and summit diplomacy?" the spokesman said.

High-level inter-governmental talks between the two Koreas scheduled for June 12 in Seoul were called off due to the disagreement over the level of delegation chiefs.

Pyongyang criticized Seoul for the aborted plans to hold high-level talks, indicating it would not seek dialogue for the time being.
