BRUSSELS - Six world powers are committed to holding a new round of nuclear negotiations with Iran as soon as possible, said a spokesman for the European Union's foreign policy chief, who represents the six in talks with Iran.

Officials from the six countries - China, Russia, the United States, Britain, France and Germany - met in Brussels on Wednesday to plan for future contact with Iran, in an effort to make progress in the decade-long rift over Tehran's atomic work.

"(The six powers) remain united in their efforts to seek a diplomatic solution to the Iranian nuclear issue," the spokesman said on Wednesday.
