Speaking to reporters in the capital Ankara on Saturday, Cavusoglu said Turkey wanted to see concrete steps by the United States to end its support for the Syrian Kurdish force.
The remarks came hours after the Turkish presidency announced in a statement that Presidential Spokesman Ibrahim Kalinand US National Security Adviser Herbert Raymond McMasterhad discussed Turkeys ongoing Operation Olive Branch in Syria's northwestern Afrin region during a telephone conversation the previous night.

Turkey says the United States has promised it for a second time to stop arming Syria-based Kurdish militants whom Ankara considers a threat to its security.
McMaster said that Washington would not give more weapons to YPG militants.
The two senior officials also agreed to boost mutual coordination and clear up misunderstandings on issues concerning Syria, the statement added.
Also on Saturday, the Turkish General Staff said in a statement that at least 394 YPG militants had been killed since the beginning of Operation Olive Branch in Afrin on January 20.
The military said that only terrorists and their positions and shelters were being destroyed, and that careful attention was being paid not to harm any civilian.
Meanwhile, more than 10,000 people demonstrated in Cologne, Germany, on Saturday to denounce the Turkish offensive in northern Syria against YPG militants.
The demonstrators held placards that read Freedom for Kurdistan and Shame on you, Europe! in the western German city.
The Syrian government has already condemned the brutal Turkish aggression against Afrin, rejecting Ankaras claim about having informedDamascus ofthe operation.
Damascus "strongly condemns the brutal Turkish aggression on Afrin, which is an inseparable part of Syrian territory," Syrias official news agency, SANA, cited a Syrian Foreign Ministry source as saying last week.
PressTV-Syria slams Turkeys brutal aggression on Afrin
The Syrian government condemns Turkeys 'brutal aggression' against the Kurdish enclave of Afrin.
"Syria completely denies claims by the Turkish regime that it was informed of this military operation," the source added.
Ankara views the YPG as the Syrian branch of the militant Kurdistan Workers' Party (PKK) that has been fighting for an autonomous region inside Turkey since 1984.
Turkish President Recep Tayyip Erdoganhas repeatedly said that Afrin should be cleared of terrorists, and demanded the deployment of Turkish troops there during a speech back in November 2016.
This is while US officials regard the YPG as the most effective fighting force against the Daesh Takfiri terrorist group in northern Syria, and have substantially increased their weaponry and technology support to the terroristgroup.
The controversy over a possible Syria border force first started on January 14 when a report emerged on Reuters saying that the military coalition led by the United States in Syria was planning to set up a large border force of up to 30,000 personnel with the aid of its militia allies.
