The two sides are slated to discuss regional crises, particularly the five-year-old conflict in Syria. Tehran and Ankara have different views on the war in the Arab country.

Turkey backs militants insists that President Bashar al-Assad should not be part of Syria’s future. Iran says the decision on Assad’s fate is up to the Syrian people and supports the Syrian army and its allies fighting militants.

Davutoglu’s planned trip is significant as the next round of Syria peace talks is scheduled to kick off in Geneva, Switzerland, on March 9.

A ceasefire agreement in Syria brokered by Russia and the United States entered into force on February 27 amid hopes the truce would end hostilities there.

The visit also comes at a sensitive juncture. Turkey and Saudi Arabia have recently announced plans for possible deployment of ground troops to Syria, prompting warnings, including by Iran, that the move could escalate the conflict.

At least four Saudi airplanes have reportedly arrived at Turkey's Incirlik base which the US and its allies use to carry out operations in the region.

Despite their differences, Turkey and Iran have largely maintained cordial diplomatic relations.
The travel will be the first high-level state visit to Iran since President Recep Tayyip Erdogan visited the country in April 2015.

The two neighbors seek to expand trade relations after the lifting of sanctions on Iran in January.

Turkey kept buying a limited amount of crude oil from Iran even under sanctions and maintained other business ties with Tehran.

Turkish companies are seeking to cash in on those commercial connections now that the sanctions have been lifted, pushing for new opportunities in the country.
