Iranian Foreign Minister Ali-Akbar Salehi said Friday that it is possible that nuclear talks between Iran and the five permanent members of the United Nations Security Council plus Germany (G5+1) are to be held in near future, the official IRNA news agency reported.

The G5+1 have some ambiguities and Iran is trying to clarify on those ambiguities, Salehi said, according to IRNA. But he did not elaborate on the nature of the ambiguities and Iran's mechanisms to solve them.

Salehi said that Iran's chief nuclear negotiator Saeed Jalili's letter to EU Foreign Policy Chief Catherine Ashton has either been sent by now or it is going to be sent, therefore it is expected that the negotiations will be held in the near future, according to the report.

Earlier this month, Salehi said that "Preparatory work has been done to go ahead with nuclear talks and consultations are underway to take next steps. I hope negotiations with the G5+1 will be held in the near future."

On Feb. 1, Salehi told the semi-official Fars news agency that Iran was ready to resume negotiations with the G5+1 and announced that Tehran would soon send a letter to the six world powers to announce its readiness for talks.

"Mr. (Saeed) Jalili as Iran's chief nuclear negotiator had earlier announced his readiness to hold talks with the G5+1 and he will announce this once again," Salehi said, adding "We hope that the meeting will be held not in a far future."

Nuclear talks between Iran and the G5+1 in Istanbul in January 2011 failed to reach any agreement as Tehran rejected any notion of suspending enrichment in exchange for trade and technology benefits, as called for by several UN Security Council resolutions passed since 2006.

The International Atomic Energy Agency (IAEA) said, on Feb. 1, that another meeting between the UN nuclear watchdog and Iran over its nuclear program would take place in Tehran on Feb. 21-22.

"The Agency is committed to intensifying dialogue. It remains essential to make progress on substantive issues," IAEA chief Yukiya Amano said in a statement.

The announcement came after a high-ranking IAEA delegation returned to the agency's headquarters in Vienna following a trip to Iran.

"The IAEA explained its concerns and identified its priorities, which focus on the clarification of possible military dimensions to Iran's nuclear programme," Amano said.

During the newly-concluded talks, the IAEA also discussed with Iran the topics and initial steps to be taken, as well as associated modalities, he added.

The spirit dominating the three-day talks between Iranian officials and the IAEA team was "positive and constructive," Iran' s official IRNA news agency said late January. The report also said the IAEA delegation, headed by chief inspector Herman Nackaerts, did not visit or inspect any nuclear site in Iran.

The talks were held behind closed doors and no details about its process or outcome were released.

Last November, the board of the IAEA adopted a resolution on Iran's nuclear program suspected of having weapons-related activities, and called for intensified dialogue to find solutions to unresolved issues.

However, Iran has said that the resolution would not stop its nuclear program, which it insists is peaceful in nature despite the West's accusation of military purposes.
