German Chancellor Angela Merkel urged Turkey on Tuesday to make progress on normalising relations with Cyprus and open its ports to traffic from the island.
EU conditions opening new chapters in talks with Turkey with opening ports to Greek Cyprus.
After meeting with Greek Cypriot leader Demetris Christofias, Merkel said Turkey needed to show "more willingness" in the resolution of its dispute with Cyprus.
You have shown "great willingness" to compromise that has unfortunately not been reciprocated by the other side, she told Christofias at a news conference during the first visit of a German chancellor to Greek Cyprus.
Greek Cyprus joined the EU as a divided island when Greek Cypriots in the south rejected the UN reunification plan in twin referendums in 2004 even though the Turkish Cypriots in the north overwhelmingly supported it.
Reunification talks focused on re-linking the two disparate sides as a loose federation began in 2008 after decades of failed efforts and conflict, but many issues remain unresolved.
Merkel said Germany's experiences of reunification could be helpful when the negotiations between Greek Cyprus and the northern part of the island were more advanced.
Turkey started accession negotiations with the EU in 2005. 13 out of 35 chapters have been opened so far. Eight chapters remain frozen since 2006 due to Turkey's policy not to open its ports to Greek Cypriot vessels who blames EU of not fulfilling its promise to establish direct trade with Turkish Republic of Northern Cyprus, though the Turkish Cypriots in the north overwhelmingly supported the UN reunification plan in twin referendums in 2004.
