Iran's Foreign Ministry Spokesman
Ramin Mehmanparast says there is no consensus in the Vienna Group to discuss a nuclear swap deal within the framework of the Tehran Declaration, Press TV reported.
"Their delay in setting a date for talks is rather confusing and demonstrates their lack of agreement on the issue," Mehr news agency quoted the Iranian diplomat as saying on Friday.
The Vienna Group comprises France, Russia and the United States and the International Atomic Energy Agency (IAEA).
"They appear to lack the willingness to enter peaceful nuclear cooperation," the Iranian spokesperson added.
Foreign ministers of Iran, Turkey, and Brazil signed the declaration in the Iranian capital of Tehran on May 17, according to which the Islamic Republic would ship 1,200 kilograms of its low-enriched uranium to Turkey to be exchanged for 120 kilograms of 20 percent enriched nuclear fuel rods to power the Tehran research reactor, which produces radioisotopes for cancer treatment.
Mehmanparast's comments on Friday come as he had earlier said that Iran would definitely not discuss a nuclear swap deal with the major world powers in the upcoming multifaceted talks.
"Definitely, our meeting with the P5+1 (Britain, China, France, Russia, and the US plus Germany), which will be held with or without the presence of the others, will not include discussions on fuel swap," he said on Tuesday.
