Iran has not yet submitted the proposals for a new package of practical measures to remove controversial issues to the International Atomic Energy Agency (IAEA), ITAR-TASS reported.
IAEA Director General Yukiya Amano made this statement at a meeting of the governing board of the agency.
"The IAEA asked Iran to offer new measures until Sept. 2 that would form the basis for a package of practical measures as part of the cooperation agreement," he added. "Iran has not done this."
At the same time, he stressed that Tehran is ready to speed up the work with the IAEA to verify the peaceful nature of its nuclear program.
"I stressed the importance of timely implementation of the framework agreement on cooperation and took into account the statements of the Iranian authorities on their firm commitment to the implementation of this agreement and the willingness to accelerate the process for removing the remaining issues," Amano added.
Iranian Deputy Foreign Minister Abbas Araghchi said Sept. 9 that Iran and "Six" (five permanent members of the UN Security Council and Germany) have agreed on the most controversial issues.
While estimating the ratio of solved and unsolved problems as 70 to 30, Araghchi expressed confidence that the sides will come to a final comprehensive agreement at an upcoming round of talks on Iran's nuclear program in New York Sept.18.
