(KRT via AP Video) (Newser) – North Korean leader Kim Jong Un said during a critical ruling party congress that his country will not use its nuclear weapons first unless its sovereignty is invaded, state media reported Sunday. Kim also said he is ready to improve ties with "hostile" nations in a diplomatic overture in the face of international pressure over its recent nuclear test and long-range rocket launch. He also called for more talks with rival South Korea to reduce misunderstanding and distrust between them and urged the United States to stay away from inter-Korean issues, according to the official Korean Central News Agency. "Our republic is a responsible nuclear state that, as we made clear before, will not use nuclear weapons first unless aggressive hostile forces use nuclear weapons to invade on our sovereignty," Kim said in a speech carried by the KCNA. He said that North Korea "will sincerely fulfill its duties for the non-proliferation of nuclear weapons and work to realize the denuclearization of the world." At the congress, Kim also announced a five-year plan starting this year to develop the North's dismal economy and identified improving the country's power supply and increasing its agricultural and light-manufacturing production as the critical parts of the program, the KCNA said.
