Turkey's foreign minister has criticized the European Union's "weakness" for not being able to get ethnically divided Cyprus to stop blocking key parts of its membership negotiations with the 28-member bloc.

Mevlut Cavusoglu said, after talks with the EU's foreign policy chief and enlargement commissioner Friday, that a deal reunifying Cyprus isn't a criterion for opening policy areas — or chapters — that EU-member Cyprus continues to obstruct.

Cavusoglu said Turkey is helping ongoing Cyprus peace talks and expects the EU to do more as well. EU Foreign Policy chief Federica Mogherini spoke of a "window of more than hope" that a Cyprus accord can be reached.

Cyprus says it won't unblock talks on six chapters, including justice, the judiciary, fundamental rights and security, unless Turkey does more to help the peace talks.
