The head of the European Commission Jean-Claude Juncker noted that the EU's hand remained outstretched to Turkey, abc News reports.
However, the European official also noted that Ankara would not get the EU membership if reinstated the death penalty.
According to Juncker, Turkey being democratic, stable and economically successful is important to the EU. He said Turkey should "move closer to Europe rather than moving away from us."
Juncker stressed the bloc is a "union of values."
"If Turkey were to introduce the death penalty, the Turkish government would definitively slam the door on EU membership."
Previously, Turkish President Recep Tayyip Erdogan declared he would approve a bill reinstating the death penalty if parliament proposed it.
