Turkish Foreign Minister Ahmet Davutoglu met separately with EU High Representative Catherine Ashton and Iran's top nuclear negotiator Saeed Jalili, on the eve of nuclear negotiations set to take place Friday in Istanbul between P5+1 (France, Germany, Russia, United Kingdom, United States, and People's Republic of China) and Iran, Anadolu agency reported.
Davutoglu exchanged views with Ashton and Jalili, said Turkish diplomats who declined to be named.
Earlier on Thursday Davutoglu hosted a dinner in the honor of high-level officials from P5+1 group, Iran and the European Union ahead of Friday's negotiations in Istanbul with Tehran over its nuclear program.
The dinner at Istanbul's Dolmabahce Palace was attended by EU High Representative Catherine Ashton, Iran's top nuclear negotiator Saeed Jalili and his deputy Ali Bagheri as well as William Burns, U.S. undersecretary of state for political affairs.
In December last year, Iran's Bagheri said talks in Istanbul could resolve the dispute over Iran's nuclear program.
"We think [the negotiations], in line with the agenda decided in Geneva, could clear the way to resolving problems," said Bagheri.
Also high-level diplomats from Britain, France, Russia, China and Germany were among Davutoglu's guests.
