Iran should negotiate the future of its nuclear program with each of the P5+1 countries separately, Supreme Leader Ayatollah Ali Khamenei's strategic adviser Ali Akbar Velayati was quoted by Mehr news agency as saying on Friday.
"We aren’t on the right path if we don’t have one-on-one talks with the six countries," Velayati was quoted as saying.
Iran and the P5+1 states - Britain, China, France, Germany, Russia and the United States - reached an interim deal in Geneva last month that freezes Tehran's nuclear program for six months in return for some sanctions relief. The allocated six months are meant to allow for time to negotiate a permanent accord.
"We have to talk with the countries separately... It would be wrong if we bring the countries into unity against us, since there are rifts among them over various international issues," he added.
