The Antalya talks are aimed at ensuring better coordination to avoid "the risk of unwanted clashes" as many countries are involved in Syria, the Turkish premier said.
Turkey, a North Atlantic Treaty Organisation ally, views the Kurdish group that dominates the Syria Democratic Forces as terrorists and has threatened to drive them from the northern town of Manbij, which the Syria Democratic Forces captured from the militants a year ago with the aid of USA -led coalition airstrikes.
The Kurdish fighters have seized considerable territory from the Takfiri terrorist group Daesh in Syria and have majorly contributed to counterterrorism operations in Iraq. This includes Iranian-backed pro-government militias.
The U.S. and Russian Federation blocked an attempt this week by Turkey and its Syrian rebel allies to take positions from Kurdish forces that have recently allied with the Syrian army in northern Syria, resulting in a major shift in momentum among the three nations sponsoring separate actors in the country's six-year civil war.
Russian Federation launched an operation against militants of the Islamic State group (outlawed in Russia) in September 2015.
His announcement stood in stark contrast to previous threats from Ankara that it would strike the Syrian Kurdish People's Protection Units (YPG) unless they withdrew from Manbij.

Snipers had also tried to deter Iraqi forces as they approached from Mosul's south. A man runs towards Iraqi special forces soldiers. That number may still rise sharply.
Turkish officials also fear that Assad's forces near Manbij could serve as a blocking force on the Turkish military to prevent its movement south to join an eventual assault on the ISIS stronghold of Raqqa.
The YPG is a key fighting force in the SDF, which spearheaded the victories against IS in the flashpoint towns of Kobane and Manbij.
Mark Toner, acting State Department spokesman, said it was aware of the situation with Mercy Corps, which he called a "valuable partner" in delivering humanitarian assistance to needy Syrian refugees. Turkey has labeled the YPG an affiliate of the separatist Turkish Kurdistan Workers' Party, which Washington and Moscow have designated a terrorist group.
Ankara has conducted a military campaign inside Syria since late August, backing Syrian opposition fighters and recapturing from IS several towns near its border. The ceasefire in Syria came into force on December 30, 2016.
Turkey is also cooperating with Russian Federation in Syria, despite them being at odds politically over the future of Syrian President Bashar al-Assad, whom Moscow backs militarily.
The United States appears to have made a decision to enlist the help of Kurdish YPG militia in a campaign to push Islamic State out of its stronghold in Raqqa, Syria, thwarting Turkey's ambitions, a senior Turkish official said on Tuesday.
