US special envoy for Syria James Jeffrey held talks in Ankara this week on the zone and other issues, including progress on a roadmap agreed last year for the northern town of Manbij to be cleared of the Kurdish YPG.
The group has been the main US ally on the ground in Syria during Washington’s fight against Islamic State.
However, Turkey has been infuriated by US support for the YPG, which Ankara considers a terrorist organization, and has repeatedly demanded that Washington cut its ties.
Following the US decision to withdraw from northern Syria, the NATO allies agreed to create the safe zone, which Turkey says should be controlled by its forces and also cleared of the YPG.
But at a news conference in Ankara on Wednesday, Cavusoglu said that the two countries had failed to agree on how deep the safe zone would be, who would control it and whether the YPG would be completely removed from the area.
“We got the impression that they want to enter a stalling process here as in Manbij,” Cavusoglu said. “We need to reach an agreement regarding the safe zone as soon as possible because we have no patience left.”
Cavusoglu also said that US military officials meeting with a YPG leader on Monday - the same day as Jeffrey’s talks at the Foreign Ministry - indicated Washington was not sincere.
The US Embassy in Ankara said in a statement later on Wednesday that the two sides were committed to accelerated and concrete progress on the Manbij roadmap, adding that Jeffrey had “forthright, positive, and productive” talks during his visit.
“There was an overall discussion on Syria and specifically for the northeast, both sides committed to accelerated and concrete progress on the Manbij roadmap, and discussed detailed proposals to enhance Turkey’s security along the Turkish border in northeast Syria,” the US Embassy said in a statement.
