Eroğlu spoke after meeting UN General-Secretary Ban Ki-moon in New York to discuss latest developments in UN-sponsored negotiations over the island's future."A resumption of negotiations with the sacrifices of Turkish side only is worrisome and poses difficulty in reaching an agreement," Eroğlu told reporters.Meanwhile, Davutoğlu also held a phone conversation with Yusuf bin Alawi bin Abdullah, Oman's Minister of Foreign Affairs, about the two country's relations.
