Erdogan said US counterpart Barack Obama floated the idea of joint action against the militants when they met at the G20 summit in China.
“Turkey will have no problem with such action,” Erdogan said.
Last month Turkey launched an operation inside Syria, targeting both ISIS and Kurdish rebels.
Turkish-backed militia drove ISIS from the border town of Jarablus, but Turkey has also been concerned with checking the advance of Kurdish forces that it regarded as terrorists.
