North Korean leader Kim Jong-un has said he is open to a summit with his South Korean counterpart, days after a proposal from Seoul to resume dialogue.

"If South Korean authorities sincerely want to improve relations between North and South Korea through talks, we can resume stalled high-level meetings," Kim said in a New Year's address broadcast by state media on Thursday.

Standing in a wood-panelled room in front of a red flag bearing the crest of the ruling Workers' Party, Kim spoke for about 30 minutes to an off-camera audience, and appeared to be reading from a script.

He outlined the intentions of his government to further develop a series of special economic and tourism zones this year, including the Kumgang Mountain resort which was open until it closed after the shooting of a South Korean tourist in 2008.

North Korean policy-setting was previously only communicated in a New Year's editorial published annually in state newspapers. Kim Jong-un, however, has turned to using public speeches to deliver his message, in a different propaganda style from his father whose voice was only broadcast once on state television.

Stalled talks

South Korea has welcomed talks offer as "meaningful".

"Our government is looking forward to holding talks between South and North Korean authorities in the near future regardless in what format," said South Korean Unification Minister Ryoo Kihl-jae at a news briefing.

South proposed on Monday to resume stalled inter-Korean talks with North to cover issues including reunions for families separated by the 1950-53 Korean War.

The two Koreas have remained technically at war as the War ended in an armistice, not a peace treaty. Reunification of the Korean peninsula has been a stated priority for both governments.

"There's no change in (our) government's stance to establish peace on the Korean peninsula by promoting trust between North and South through dialogue and exchange, and the development of normal relations," Lim Byeong-cheol, a spokesman for South Korean Ministry of Unification told the Reuters news agency by phone.

North Korea has in the past signalled intent to improve relations with the South, but subsequent provocations from the North or US-South Korean military exercises have stalled progress between the two Koreas.

"Annual large-scale (US-South Korean) war exercises are a source of heightened tensions on the Korean peninsula and increase the threat of nuclear war," Kim said in the speech.
