Turkey's foreign minister says he has discussed the next round of nuclear talks between Tehran and six world powers with Iran's new acting foreign minister.
The talks will held in Istanbul next month.
Turkey's Ahmet Davutoglu said he met Iran's Ali Akbar Salehi at a regional economic summit late Wednesday. Salehi, who is accompanying Iranian President Mahmoud Ahmadinejad, is making his first international appearance since replacing Iran's sacked foreign minister last week.
Davutoglu said Thursday that Turkey was working toward "reducing the environment of tension" over Iran's nuclear program.
Iran held a first round of talks with officials from the U.S., China, Russia, France, Britain, Germany and the European Union in Geneva earlier this month.
Ahmadinejad meets Turkish PM
Ahmadinejad held one-hour closed door talks with Turkish Prime Minister Recep Tayyip Erdogan late on Wednesday, and on Thursday joined leaders from Pakistan, Afghanistan and Central Asian states for a summit of the 10-member Economic Cooperation Organization (ECO) which is expected to produce few results.
Ahmadinejad, who was warmly greeted by Turkey's President Abdullah Gul, is due to give a news conference later on Thursday which might be the highlight of the summit.
