Iran on Sunday said that the failure of talks held in New York over Iran's nuclear programmes was "natural," the official news agency IRNA reported.
Diplomats from the six world powers involved in the nuclear dispute with Iran met in New York on Saturday for adopting possible new sanctions against the Islamic state but eventually failed to reach any agreement, dpa reported.
"It was quite natural that the talks would fail as without adopting a pragmatic approach and without acknowledging Iran's legitimate right to pursue civil nuclear technology, no clear results can be gained (by the world powers)," Foreign Ministry Spokesman Ramin Mehmanparast told IRNA.
"The world powers are quite aware that Iran's nuclear projects are peaceful and have no deviation (towards military programmes) and this has also been confirmed by the International Atomic Energy Agency (IAEA)," the spokesman added.
Mehmanparast said the Iranian dossier should be evaluated only by the IAEA and without any political considerations.
"Even some of the involved countries know well that adopting sanctions would be futile and a political approach would have no suitable results," the spokesman said.
Tehran has several times announced that the country would welcome a return to negotiations with world powers over its controversial nuclear programmes if a pragmatic approach was witnessed and no threats made.
Iran says that as signatory of the Non-Proliferation Treaty and member of the IAEA, it has the right to pursue civil nuclear technology and would not allow world powers to deprive the Islamic state of this right for political reasons.
The West fears, however, that Iran is pursuing nuclear weapons and demands from Tehran to suspend parts of its projects to build confidence.
