A senior Iranian diplomat has criticized the United States and its Western allies for killing any chance of reaching an agreement about the Islamic Republic's nuclear energy program, Press TV reported.
"The United States and its allies have adopted hostile approaches and unconstructive positions in the past years, thereby killing the chance of obtaining any agreement (on Iran's nuclear energy program)," Mostafa Dolatyar, the director-general of the Department for Political and International Studies of the Iranian Foreign Ministry, told a seminar on nuclear non-proliferation in Moscow on Sunday.
"Over these years, the US has neglected all the positive steps Iran has taken... throughout its negotiations with the P5+,1 -- the US, France, Britain, Russia, and China plus Germany and the European sides have regrettably followed in the footsteps of Washington's hostile policy against Tehran," he said.
Dolatyar called for the return of Iran's nuclear case from the United Nation's Security Council to the International Atomic Energy Agency (IAEA).
He said the UN nuclear monitoring body should consider Iran's nuclear energy program within the framework of international conventions.
"Iran has on numerous occasions shown flexibility, but it has been responded with consecutive Security Council resolutions," Dolatyar added.
The United States, Israel and some of their allies have repeatedly accused Iran of pursuing non-civilian objectives in its nuclear energy program.
Iran rejects the allegations, arguing that as a signatory to the Non-Proliferation Treaty (NPT) and a member of the IAEA, it is entitled to develop and acquire the nuclear technology for peaceful purposes.
The IAEA has conducted numerous inspections of Iran's nuclear facilities, but has never found any evidence indicating diversion in Tehran's nuclear energy program toward military purposes.
