International Minister Mevlut Cavusoglu told journalists that Washington was too strongly involved with USA -allied Syrian Kurdish fighters and was stalling on plans for the risk-free zone.
Their visit comes days after Turkish and USA troops conducted their first joint ground patrol of the "safe zone" that Ankara has been pressing for in the Kurdish-administered region.
On August 7, Turkish and U.S. military officials agreed to set up a safe zone in northern Syria and develop a peace corridor to facilitate the movement of displaced Syrians who want to return home.
On Sunday, Turkish and United States troops carried out their first joint military land patrol there.
The Syrian Kurdish fighters were being the major US allies in the war versus the Islamic Point out team in Syria. The deal envisages withdrawal of the People's Protection Units (YPG) towards the south of the safe zone. US troops on Saturday also conducted patrols with the local Syrian Kurdish-led forces, which annoyed Turkey. "We are ready to provide every necessary support to the USA investors", he highlighted.
"Turkey's options are ready", Cavusoglu said.

The minister's comments came as two USA military officials were visiting Turkey for talks on what Ankara calls "safe zone". The U.S. and Syrian Kurdish forces refer to it as a "stability system".
The two countries agreed a road map in May 2018 to clear the YPG from Manbij in northern Syria, but Turkey says the withdrawal never happened as agreed.
The US military delegation, headed by Lieutenant General Stephen Twitty, deputy commander of the US European Command (EUCOM), and Lieutenant General Thomas W Bergeson, deputy commander of US Central Command (CENTCOM), will visit the Joint Operation Center in Sanliurfa, southeast Turkey on Wednesday.
