How will Iran and Turkey deal with Kurdish state bid?

Iran and Turkey may seem like unlikely partners following events of the past few years, especially in Syria. But they are saying the same thing about the recent "Yes" vote in the Kurdish referendum, as neither want Kurdish people living in northern Iraq to secede. Iran's Supreme Leader Ali Khamenei and President Hassan Rouhani welcomed him to discuss curbs on the Kurds' dream of their own homeland. Turkey is threatening to stop buying oil from the Kurdish Regional Government in Iraq, while Iran has mobilised troops on its border with the region. What more can de done, beyond an economic embargo?
