Turkish President Recep Tayyip Erdogan and his Russian counterpart Vladimir Putin - two key players involved in the conflict in Syria - are due to hold another meeting to discuss the departure of US troops from the war-torn country.
The meeting is expected to take place this month, Turkey's state news agency Anadolu reported on Sunday. Both presidents had agreed that a second meeting on the topic should take place soon, Putin's spokesman said.
Erdogan and Putin last met on the sidelines of the G20 summit in Buenos Aires on December 1. 
Turkey supports the rebel opposition in Syria, while Russia along with Iran is a major supporter of the government of Syrian President Bashar al-Assad. 
One of the lingering questions about the US withdrawal from Syria is whether Turkey will take over the fight against Islamic State militants in the country.
Russian and Turkish foreign and defence ministers last met in Moscow at the end of December to discuss Syria.
US National Security Adviser John Bolton said he would discuss the withdrawal of US forces when he meets Defence Minister Hulusi Akar and intelligence chief Hakan Fidan in Turkey on Tuesday. He is currently in Israel for talks also focusing on the Syrian conflict.
