World powers and Iran will hold follow-up talks over Tehran's nuclear program in Istanbul on July 3, the Turkish government has said.
Foreign ministry spokesman Selcuk Unal said the meeting was "essentially technical" in nature.
The Istanbul gathering is being held to see whether there is enough common ground to return to full-fledged talks.
It was scheduled during strained talks in Moscow earlier this month.
That meeting between Iran and the so-called P5+1 group failed to make progress on the crisis.
The group includes permanent UN Security Council members Britain, China, France, Russia, and the United States, plus Germany.
World powers suspect Iran's nuclear program has military aims and have demanded Tehran stop enriching uranium.
Iran says its nuclear program is for civilian purposes.
