"If we join forces, they [US] have their own special forces and we have our special forces," the minister was quoted as saying by AFP.
"The subject we are discussing with the Americans is the closure of the Manbij pocket as soon as possible… and the opening of a second front," he said.
Cavusoglu added that the "second front" could launch an offensive on Raqqa, the de-facto capital of the Daesh caliphate.
The US supports Kurdish forces in northern Syria in their fight against Daesh militants.
Ankara has long been angered over the US support for Kurdish fighters.
Earlier this week, Turkey blasted the United States after images were posted online showing US Special Forces in Syria wearing the insignia of the Kurdish People’s Protection (YPG) units, opposed by Ankara.
YPG fighters are viewed by Ankara as an extension of the Kurdish Workers’ Party, or PKK, which is labeled a terror organization by Turkey, the United States, and the European Union, but not by Russia and the United Nations. Turkish President Recep Tayyip Erdogan even called on Washington to make a choice between Ankara and the YPG.
