Spokesman for European Union Foreign Policy Chief Catherine Ashton announced Monday that the world powers will hold the new round of nuclear talks with Iran in Istanbul on April 14.

Iran’s Supreme National Security Council announced that the first round of talks between Tehran and the 5+1 group will take place  in Istanbul on April 14.

In a statement issued Monday, Iran stated that “the two sides have agreed to hold the next round of talks in Baghdad,” adding that “the date of the Baghdad talks will be decided after the end of the Istanbul talks.”

Spokesman for European Union Foreign Policy Chief Catherine Ashton has announced earlier Monday that the world powers will hold the new round of nuclear talks with Iran in Istanbul on April 14.

According to AFP, Michael Mann said that “we have agreed to launch talks in Istanbul on April 14.”

“We hope that this first round will produce a conducive environment for concrete progress… We are of course aiming at a sustained process,” Mann added.

In the same context, Iran urged "honesty" at the talks, pointing out that “we also will make an honest effort so that both sides reach a win-win conclusion."

Speaking to the Iranian parliament's website, Iranian Foreign Minister Ali Akbar Salehi warned that “the P5+1 group should not try to impose conditions on the talks before they begin,” rejecting reports that “the West was going into the talks with demands that Iran close an underground nuclear bunker in Fordo, and that it halt enriching uranium to 20 percent.”

“Those (demands) have been raised only by the media and we cannot make a judgment based on them," the Iranian foreign minister said.

“Putting forward preconditions before the meeting happens is equivalent to reaching a conclusion before the negotiations start. It is completely meaningless. No one will accept preconditions before the talks," he added.
