Six world powers, including China
, have agreed to start drawing up new sanctions on Iran over its nuclear program, a source has revealed.
Representatives of the US, Britain, France and Germany were said to have reached agreement with Beijing and Moscow
during a conference call.
The unnamed source, with knowledge of the talks, said: "It has been agreed with China
to start drawing up sanctions on Iran.
"Drawing up of a Security Council resolution is to begin in the next few days."
Iran has been conducting low-level enrichment of uranium in the central city of Natanz for several years, in defiance of three sets of UN sanctions.
World leaders accuse Iran of developing a nuclear arsenal but Tehran says its nuclear program is intended only to generate electricity.
The US, Britain, France, Germany and Russia have been pushing for "strong" new UN sanctions against Iran over its nuclear drive.
Diplomats say China has been slowly falling in line with the other powers involved in the negotiations on Iran but Beijing wants any new steps to be weak.
