SEOUL--North Korea on Friday called for an end to hostile relations with the United States, vowing to work towards a nuclear-free peninsula seven months after its last atomic test angered the world community.

The call was made in a policy-setting New Year joint editorial of the communist country's state newspapers. North Korean people must learn and memorize the editorial, which is seen as ideological guidance for the year ahead.

"The fundamental task for ensuring peace and stability on the Korean Peninsula and in the rest of Asia is to put an end to the hostile relationship between the DPRK (North Korea) and the USA," the editorial said.

"It is the consistent stand of the DPRK to establish a lasting peace system on the Korean Peninsula and make it nuclear-free through dialogue and negotiations," the editorial said, according to Pyongyang's Korean Central News Agency (KCNA).

North Korea left six-party nuclear disarmament talks in April last year in protest at international censure over its launch of a long-range rocket. In May, it staged its second nuclear test since 2006.

US envoy Stephen Bosworth visited the communist nation last month and reached a "common understanding" on the need to resume the talks, which group the two Koreas, Japan, China, Russia and the US. However, no date has been fixed.

In Washington, a State Department official said North Korea should demonstrate its good faith by returning to the six-party talks.

"Actions speak louder than words," the official said, speaking on condition of anonymity. "A good step forward would be to return to six party talks."

South Korea's unification ministry said this year's editorial is distinctive in emphasizing "dialogue and negotiations" as last year's editorial reaffirmed its commitment to denuclearization and peace without mentioning dialogue.

Analysts said the use by the North of the New Year's Day joint editorial was significant.

"This means that North Korea's ordinary people will start being educated about Pyongyang's push for an end to enmity with the US," Professor Kim Yong-Hyun of Dongguk Univerity told AFP.

Professor Yang Moo-Jin of the University of North Korean Studies also said the editorial indicates that Pyongyang will actively pursue dialogue this year, focusing on the conclusion of a peace treaty and nuclear disarmament.

The Korean peninsula remains technically in a state of war because the 1950-53 conflict between North and South ended with an armistice and not a peace treaty.

"It means the North will not call for an end to US hostility as a pre-condition for giving up its nuclear weapons but it will push for both goals -- an end to hostile relations and denuclearization -- at the same time," Yang said.

The editorial also put great emphasis on what it called bringing about "a radical turn in the people's standard of living" in impoverished North Korea.

This would be achieved by quicker development of light industry and agriculture, KCNA said.

"Our building of the country into an economic giant is aimed, to all intents and purposes, at radically improving the people's standard of living," the editorial quoted North Korea's all-powerful leader Kim Jong-Il as saying.

Professor Kim Yong-Hyun said the North was now whipping up its people to increase production after the country last month carried out a surprise currency revaluation aimed at reasserting government control of the economy.

The editorial warned neighboring South Korea against "committing acts that may aggravate the confrontation and tension, and take the road of respecting the inter-Korean declarations, promoting north-south dialogue and improving the relations between both sides."
