Leaders from Iran and Turkey called Saturday for cooperation in ending conflicts and sectarian violence in the region.
Turkish Prime Minister Ahmet Davutoglu, speaking at a joint news conference in Tehran, said Iran and Turkey could collaborate to stop bloody fratricides.
Iranian Vice President Eshagh Jahangiri said Iran and Turkey had disagreed about how to handle the Syrian crisis, but that both sides were determined to move toward stability.
Turkey is a main backer of the rebels fighting to topple Syrian President Bashar al-Assad, while Iran, along with Russia, support the Assad government.
Both men also said they were aiming to increase bilateral trade to $30 billion.
Trade between Turkey and Iran was reported at around $10 million in 2015, a drop from previous years.
