President Donald Trump's announcement last month that he had made a decision to withdraw the 2,000 U.S. troops there stunned allies who have joined Washington in the battle against ISIS militants in Syria.
Over recent weeks, senior USA officials have offered confusing and contradictory accounts of the terms and speed with which the U.S. is leaving.
He said the United States envoy for Syria, Jim Jeffrey, had travelled to northeast Syria this week and would soon go to Ankara for talks, including on moving forward a UN-led political process to end the eight-year long conflict in Syria.
Mr Pompeo is touring the Middle East to try to reassure allies following President Donald Trump's abrupt announcement last month that United States forces would withdraw from Syria.
Akar said Turkey was determined to end terrorism wherever it may be, which never means Hamas terrorism - it's just code for killing a lot of Kurds.
Turkey has recently warned that it would launch combat operations across its southern border into northeastern Syria against Kurdish forces who have been allied with the U.S.in the fight against ISIS.
A USA official told ABC News that in recent days military equipment has been moved out of Syria into Iraq.
"Many details (are) still to be worked out but I'm optimistic that we can achieve a good outcome", he said.
Turkey already occupies and effectively runs local affairs in vast territories in northwestern Syria, including Afrin which came under an intense Turkish military campaign past year that resulted in thousands of deaths and displacement of some 160,000 locals as Erdogan promised to give the region back to the "rightful owners, Arabs".
President Donald Trump confirmed a Syria withdrawal Sunday, but shifted slightly on the timing, saying "we won't be finally pulled out until [the Islamic State] is gone".
Pompeo stressed those fighting alongside the US are not terrorists and deserve protection.
Bolton said last Sunday that the Trump administration would delay pulling American troops from Syria until Turkey assures the US that Kurdish forces won't be touched. "Our preparation continues intensely", the Turkish defense minister said Friday. But in coming weeks, the contingent of about 2,000 troops is expected to depart even as the White House vows to keep pressure on the Islamic State group.
Relations between the two North Atlantic Treaty Organisation allies have been strained over U.S. backing for the Kurdish YPG, which Turkey views as an extension of the outlawed Kurdistan Workers Party (PKK) waging a decades-long insurgency on Turkish soil.
Turkey considers many of Syria's Kurdish groups to be terrorists and has pledged to attack them.
There has been confusion over plans to implement Trump's pullout order and threats from Turkey to attack the Kurdish fighters, who Ankara views as terrorists due to their ties to insurgents within Turkey.
