The main players in a pending sanctions resolution against Iran solidified seemingly intractable positions Tuesday, overshadowing the regional security summit that brought them all to Istanbul.

Iranian President Mahmoud Ahmadinejad said his country would reject talks on its nuclear program if slapped with new sanctions by the U.N. Security Council as Turkey tried to convince council-member Russia to give the deal it and Brazil brokered a chance.

“I have said that the U.S. government and its allies are mistaken if they think they can brandish the stick of [a sanctions] resolution and then sit down to talk with us; such a thing will not happen,” Ahmadinejad told a news conference in Istanbul. “We will talk to everyone if there is respect and fairness, but if someone wants to talk to us rudely and in a domineering manner, the response is known already.”

The third summit of the Conference on Interaction and Confidence-Building Measures in Asia, or CICA, which brought key players on the Iranian dispute together in Turkey this week, comes as the U.N. Security Council geared up for a vote on a new round of sanctions against Tehran.

Though no date has been officially set for the vote, Mexico’s U.N. Ambassador Claude Heller, the current council president, said Monday that members have decided “to have a vote this week.”

Turkey and Brazil, both non-permanent members of the Security Council, oppose a new round of sanctions against Iran, standing behind their swap deal as an opportunity for a diplomatic resolution to the nuclear standoff. In the deal signed May 17 by the three countries, Iran agreed to send about half of its enriched uranium to Turkey in exchange for nuclear fuel that can be used only for a medical reactor in Tehran.

The Iranian leader urged the international community not to brush aside Turkey and Brazil’s efforts. “The meeting in Tehran created an opportunity for the U.S. administration and for its allies and we still hope that they will be able to use this opportunity,” Ahmadinejad said. “We say that opportunity will not be repeated.”

Behind closed doors, Turkey is still pushing the parties involved to accept the swap deal. “We are telling the Iranians to demonstrate that they will stick to the agreement and Westerns to avoid any steps that will risk the deal,” a senior Foreign Ministry official told the Hürriyet Daily News & Economic Review.

Ahmadinejad said Tehran was still waiting for a response from the International Atomic Energy Agency on the deal. According to reports, the “Vienna Group” of countries, made up of the United States, Russia and France, has drawn up a joint response to Tehran’s proposal and is expected to hand it to IAEA.

Russia, which has indicated it will support the sanctions resolution, said a consensus had been reached on the matter.

“We have worked actively on the Security Council resolution and ... a consensus has been reached,” Russian Prime Minister Vladimir Putin said at a news conference held with his Turkish counterpart, Recep Tayyip Erdoğan.

Putin added, however, that the sanctions should not put the people of Iran “under difficulty” and should not prevent Iran’s right to develop peaceful and civilian nuclear energy.

Iranian sources said Tehran has been seeking a face-to-face meeting between Ahmadinejad and Putin, something Russian diplomats said was impossible due to the premier’s heavy schedule. No meeting had been held when the Daily News went to press.

A Russian diplomat, speaking with the Daily News on condition of anonymity, said the deal brokered by Turkey and Brazil was a “good step in the right direction” but urged Iran to cooperate further. 

“This deal is not solving the problem,” the diplomat said. “The problem is still there.”
