President Recep Tayyip Erdogan says the EU must open new chapters in Turkey’s accession negotiations.

Otherwise Ankara had nothing to discuss with the EU and would say “goodbye,” Reuters reported on Tuesday.

Erdogan spoke after EU Neighborhood Policy and Enlargement Negotiations Commissioner Johannes Hahn told the agency that “Turkey under Erdogan has turned its back on joining the bloc.”

“From now on there is no option other than opening the chapters you have not yet opened. If you do not open, goodbye,” Erdogan said at a ceremony to mark his return to the ruling AK Party.
