talks SEOUL, South Korea, Jan 3, SPA -- The main U.S. negotiator on North Korea said Saturday he believes the next round of international arms talks with the communist state could produce real progress. «I think we do have some reason to believe we can make some progress,» said Assistant Secretary of StateChristopher Hill upon arriving in Seoul to coordinatestrategies for next week's six-nation talks in Beijing. «From all accounts it was a very useful couple of days'discussions,» Hill told reporters. The negotiations, involving China, Japan, the two Koreas, Russia and the U.S., have made little headway since their first and only agreement in September 2005, in which North Korea said it would give up its nuclear program in exchange for aid and security guarantees.--SPA www.spa.gov.sa/422661
