TEMPO.CO, Seoul - North Korean leader Kim Jong Un called this week's accord between the rival Koreas "a landmark occasion" paving the way for defused military tension and improved ties, but said it was the strength of its armed forces that made the deal possible.

North and South Korea agreed early on Tuesday to end a military standoff that sparked an exchange of artillery fire and had ratcheted up tension on one of the world's most heavily-fortified borders.

The two sides also agreed to open a new channel of dialogue to discuss a range of issues with the aim of improving ties, raising hopes for a fresh push to restore talks and exchanges that had been cut off since 2010.

"The joint press release published at the contact provided a crucial landmark occasion of defusing the acute military tension and putting the catastrophic inter-Korean relations on the track of reconciliation and trust," the North's KCNA news agency on Friday quoted Kim as saying in a meeting with military aides.

Kim noted the accord was reached "thanks to the tremendous military muscle with the nuclear deterrent for self-defence built by the great party as a pivot and matchless ranks single-mindedly united around the party," KCNA said.

The comments were made at an enlarged meeting of the Central Military Commission of the North's ruling Workers' Party of Korea, the same venue led by Kim last week that warned of military action unless Seoul stops the propaganda broadcasts.
