A recent United Nations report said at least 15,000 have been displaced since the start of the Turkish military operation against Kurdish fighters in Afrin.
US Secretary of State Rex Tillerson and his Turkish counterpart Mevlut Cavusoglu said after talks in Ankara that the two sides would set up working groups to solve key issues that have bedevilled relations. Turkey's President Recep Tayyip Erdogan earlier this month accused Washington of sending in 5,000 truckloads of weapons to the YPG in Syria, as well as 2,000 planeloads of arms.
Washington has warned that Turkey's operation against the People's Protection Units (YPG) Kurdish militia in the Afrin region of Syria risks distracting from the fight against jihadists.
Earlier this week, Turkey demanded the U.S. expel the YPG from the Syrian Democratic Forces (SDF) coalition, which has been fighting Islamic State of Iraq and the Levant (ISIL) in Syria with support from the US.
The US-Turkey ties have been strained by a series of events since the failed coup to topple Erdogan in 2016 which was blamed on the Muslim cleric Fethullah Gulen, who lives in exile in the US.
However, the Syrian Army maintains that they will continue to allow the Kurdish forces to resupply the area from within their own territory in Aleppo. "We've decided and President Erdogan decided last night we needed to talk about how do we go forward".
Analysts believe U.S. - Turkey relations may worsen if Turkey backs its threat to invade the city of Manbij in Syria, which is under the control of the YPG, and in which there are American military bases.

Ankara considers the YPG to be an arm of the PKK, a banned group that has waged a decades-long insurgency in Turkey.
Turkey and the United States on Friday agreed to work together in Syria after weeks of tensions over Ankara's latest cross-border operation that raised fears of a military confrontation between the two North Atlantic Treaty Organisation allies.
And Washington has expressed concern that several of its citizens-as well as at least two Turkish employees of United States missions-have been caught up in the post-coup crackdown.
Kino Gabriel, the SDF spokesmanm said the "fundamental route" to get reinforcements to Afrin is via government forces, adding, "There are understandings between the two forces. for the sake of delivering reinforcements."
"We hide in olive gardens with our civilian outfits on to be safe", he said.
Zaharova also said the US had "occupied" a 55-kilometer (34-mile) zone in southern Syria near the village of Al Tanf.
