The Turkish Foreign Ministry said in a statement that a declaration issued by the leaders of France, Italy, Greece, Portugal, Spain and Malta shows the EU cannot be a "neutral and trusted actor" to resolve the dispute over divided Cyprus.
The ministry statement called on EU states to acknowledge Turkish Cypriots' equal rights over the island's resources. It added that Turkey, which has sent a drill ship to Cyprus' western coast, is determined to protect those rights.
Cyprus was split in 1974 when Turkey invaded following a coup by supporters of union with Greece. Cyprus' government hasn't said so publicly but it has issued international arrest warrants against the ship's crew and foreign company officials assisting in the drilling.
Speaking after talks with his Emirati counterpart, Cypriot Foreign Minister Nikos Christodoulides said Turkey's actions were part of its "concerted strategy to exert control in the eastern Mediterranean" over energy issues. He accused the country of putting regional peace and stability at great risk.
Christodoulides said Cyprus expects Turkey to end its "gunboat diplomacy" in order to pave the way for a resumption of stalled talks aimed at reunifying the ethnically divided island nation.
