The US nuclear negotiator warned that time was running out Tuesday as he opened a new round of talks with his North Korean counterpart to resolve a deadlock over the communist nation's nuclear program. Still, neither side expected to reach a conclusive deal during the day-long talks at the US Embassy in Singapore. "We are not looking for an agreement," Assistant Secretary of State Christopher Hill, the top US nuclear negotiator, told reporters before starting talks with North Korean Vice Foreign Minister Kim Kye Gwan. "I think we are looking to have a consultation on some of the issues that have kept us apart for several months and certainly I will be discussing the fact that we are kind of running out of time," Hill said. No details of the talks were released when the two officials broke for lunch.
