On the eve of the new round of nuclear talks with the International Atomic Energy Agency (IAEA), Iran insisted on its "rights" to civilian use of nuclear technology, while announcing that it is ready to register nuclear weapon ban decree as an "international document."

On Tuesday, Iran's Foreign Ministry spokesman Ramin Mehmanparast said that a religious decree (fatwa), issued earlier by the country's supreme leader, regarding a ban on pursuing nuclear weapons is binding for the Islamic republic and it is ready to register the fatwa as an "international document."

In February 2012, Iran's supreme leader Ayatollah Seyyed Ali Khamenei said the country considers seeking and acquiring nuclear arms as a "sin" and "dangerous" for human being.

The double approach of sticking to "peaceful" nuclear rights and expressing openness to negotiations with the powers is not a novel policy by the Islamic republic regarding the debates over its nuclear program, however, in the eyes of Iranian government, the move to turn a religious decree into an international obligation is a step that can reflect the flexibility of the Iranian officials in the nuclear row.

Talking to reporters in his weekly briefing, Mehmanparast said Tuesday that Iran has repeated his opposition to the use of weapons of mass destruction (WMD) and is "ready for this fatwa being registered as an international document."

Registration of the fatwa as an international document will help disarm Western countries, which are trying to impose their wills on Iran, he said, urging an end to the spat between the West and Iran about the latter's nuclear program.

The spokesman's remarks came a day ahead of the new round of talks between Iran and a delegation from the IAEA in Tehran.

Iran and the IAEA held a meeting in December 2012 over the remaining issues of Iran's nuclear activities. Both sides announced progress in their talks toward an agreement that the IAEA believes would allow it to resume inquiry into the nuclear facilities in Iran.

The IAEA said that it looked forward to finalizing the framework in the new round of discussions in Tehran on Wednesday and starting implementing it soon.

Expressing hope that "all the nuclear rights" of his country be recognized and the new round of talks with the IAEA bear fruits " soon," the Iranian spokesman reiterated that Iran is also ready to take steps to remove the technical concerns over its nuclear activities.

On Monday, Mehmanparast said "We are ready to allay concerns they (the IAEA) may have and remove certain ambiguities" stressing that recognizing the Islamic republic 's rights and putting an end to pressurizing the country would be the best solution.

On the day, head of Atomic Energy Organization of Iran (AEOI) Fereidoon Abbasi said that Iran had made progress in the field of nuclear technology despite the U.S.-engineered sanctions against the Islamic republic, Press TV reported.

"We are self-sufficient in discovery, extraction and production processes (of nuke-related materials) and we do not need (help from) other countries," Abbasi was quoted as saying.

The West has accused Iran of secretly developing nuclear weapons under the guise of its civilian nuclear program, a charge Tehran has consistently denied.

Abbasi stressed that "when a country acquires the nuclear technology, it shows that it has gone beyond the boundaries of basic technical and engineering sciences."

"We have made good progress in the design and construction of reactors, and Arak's heavy water (facility) is fully operational, and the country's nuclear energy program and fuel cycle are being developed using indigenous know-how," said the Iranian official.
