South Korea will try to hold "regular and systemic" dialogue with North Korea, a senior government official said Tuesday, boosted by a landmark inter-Korean deal on ending the latest military crisis.

Asked about the prospects of inter-Korean ties, the Unification Ministry official told reporters, "(A new phase) has just begun. We will regularize and systematize talks between the South and North Korean authorities."

The South regards the North as having acknowledged its responsibility for and apologized for the Aug. 4 land mine blast, he said.

Seoul called for Pyongyang to admit its role in the incident, which maimed two South Korean soldiers, offer an apology, punish those responsible and take measures to prevent the recurrence of a similar case.

In the agreement reached earlier Tuesday, the North "expressed regret over the recent mine explosion" that occurred in the Demilitarized Zone separating the two Koreas.

"Although the North did not offer a direct and clear apology, we need to compare the agreement this time with the North's attitudes toward its past provocations," the official said on background.

It's the first time that Pyongyang expressed regret over its attack in a formal accord with the South, he stressed.

The South also technically secured the North's promise not to repeat such an attack, putting a clause into the deal that it will resume loudspeaker propaganda broadcasts along the DMZ if an "abnormal case" occurs, the official said.

The South demanded the punishment of those who are involved in the incident, but the North rejected it, he said.

Throughout the three days of the Panmunjom negotiations, the official added, the South focused on the land mine attack, while the North wanted to talk more about "future inter-Korean relations."

There were no discussions on the South's May 24th sanctions on the North, although Pyongyang raised the issue of resuming a joint tour business at Mount Kumgang on its east coast, he said.

The two Koreas are expected to hold a reunion event next month for families separated by the 1950-53 Korean War at a resort on the mountain.

Under the May 24th sanctions for the North's deadly torpedo attack on a South Korean warship in 2010, Seoul has suspended all economic cooperation projects with Pyongyang except for the Kaesong industrial complex. (Yonhap)
