British and United States officials are due to meet senior United Nations experts in Vienna on Monday to co-ordinate efforts to ensure Libya honours it nuclear disarmament pledges.
US Under-secretary of State John Bolton and British officials will see Mohamed ElBaradei, director general of the International Atomic Energy Agency at its headquarters.
US State Department spokesman Richard Boucher said he expects the three-way initiative will proceed smoothly.
There has been a difference of view as to how large the IAEA disarmament role should be relative to the US-British effort. The three sides have been attempting to bridge the differences.
The IAEA has said Libya was nowhere near producing a weapon, but Washington and London contend it was further along than the agency realises.
Bolton met recently with British officials in London to prepare for next week’s talks.
Libya announced on December 19 it would abandon its quest for weapons of mass destruction.
