Turkey's Foreign Minister Ahmet Davutoglu said that Turkey wanted settlement of the issue in line with interests of all concerned parties and on the basis of mutual respect.
"Therefore, if there is any mission Turkey can assume, we are ready to undertake it," Davutoglu told AA correspondent.
Davutoglu had talks with Iran's President Mahmud Ahmadi-Nejad and Foreign Minister Manuchehr Motaki in the Iranian city of Tabriz.
"What is important is to solve the controversy through diplomatic means and we think this solution is possible," Davutoglu said.
Davutoglu also said, "we should help each other in very important issues affecting global and regional peace, and end this match in the best way."
The minister defined his talks with Ahmadi-Nejad and Motaki as comprehensive, and said they discussed bilateral and international relations.
Davutoglu said Turkey and Iran had a close friendship and confidence in each other.
Not only Ahmadi-Nejad but also Motaki once more reaffirmed that confidence, he also said.
Also, Motaki commented on International Atomic Energy Agency (IAEA) director general Mohamed ElBaradei's remarks, and said Iran was not in favor of always having the ball in its court.
ElBaradei said earlier on Friday that "the ball was very much in Iranian court" till the end of December.
Motaki said incidents should develop in a way that concerned parties shared and reached a multi-lateral result.
Davutoglu is expected to return to Turkey later in the day.
