SEOUL (AFP) - 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 New Year joint editorial of the communist countrys 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 Pyongyangs 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. Analysts said the use by the North of the New Years Day joint editorial was significant. This means that North Koreas ordinary people will start being educated about Pyongyangs 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 peoples 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 peoples standard of living, the editorial quoted North Koreas 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 state control on the economy. The editorial warned neighbouring 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.
