President Recep Tayyip Erdogan said that preliminary work for the upcoming Astana Summit which will be held Sept. 14 has been finished and added that the steps taken toward establishing peace in Syria will hopefully be finalized in Astana.

Axar.az reports that speaking at a news conference with Kazakh President Nursultan Nazarbayev in Astana, Erdogan said that the outcome of Astana will determine the success of Geneva process.

He also noted that Turkey and Kazakhstan should work together to boost bilateral trade ties between the two countries.

"Our goal is to boost the trade volume to $5 billion [from $2 billion] as soon as possible, as we previously said" Erdogan said, adding that both countries have the potential to achieve this goal.

Meanwhile, the Kazakh president said that Turkey and Kazakhstan collaborate on a number of issues, including regional problems and other projects.

Deputy Prime Minister Hakan Cavusoglu, Foreign Minister Mevlut Cavusoglu, Presidential aide İbrahim Kalın and Turkey's Ambassador to Astana Nevzat Uyanık also attended the meeting between the two leaders.

On May 4, Russia, Turkey and Iran signed a deal in the Kazakh capital Astana to establish de-escalation zones in Syria.

The May 4 de-escalation zone agreement envisages the halt of hostilities between Assad regime forces and moderate opposition groups within the zones as well as the creation of conditions for humanitarian access, medical assistance, the return of displaced civilians to their homes and the restoration of damaged infrastructure. The guarantor states previously agreed to take all measures necessary to continue fighting Daesh, al-Nusra and other terrorist groups both within and beyond the de-escalation zones.
