North Korea's demands for what it should receive in exchange for abandoning its nuclear weapons program snarled talks Sunday on a draft agreement at international disarmament negotiations. Deputy leaders of the six delegations spent five hours discussing a Chinese-drafted proposal, a South Korean official said . But the negotiations ended their sixth day without an agreement and South Korea's main nuclear envoy said more consultations were planned Monday, AP reported. South Korean Deputy Foreign Minister Song Min-soon said talks Sunday focused on «what corresponding measures other parties will take» in return for an agreement by the North to dismantle its nuclear weapons program. The North has demanded concessions such as security guarantees and aid from Washington before it eliminates its weapons program, while the United States wants to see the arms destroyed first. The North has also insisted that it be allowed to run a peaceful nuclear power program, something Washington objects to out of proliferation concerns. «We are trying to come up with an agreed statement which contains all the key points that have been discussed so far, but how long it will take remains to be seen,» Song said.
