The four-member Iranian delegation, led by Jalili, would arrive in Istanbul on Friday this week, and would reside at that city's Hilton Hotel.
A number of Iranian reporters and photo journalists, too, would be accompanying Jalili in this trip.
The Iran - the G5+1 (comprised of the UN Security big five plus Germany) talks would be held at Istanbul's Lutfil Kirdar Hall.
The Islamic Republic of Iran's Ambassador to Turkey, Bahman Hosseinpour, who is now in Tehran, would be heading for Istanbul on Thursday and would be personally monitoring the sensitive event.
In addition, a large number of representatives of the international news media, reporters, cameramen and photojournalists have been dispatched to, or would be heading for Istanbul to give full coverage to these negotiations.
After a year of stalled talks, Iran and the G5+1 eventually accepted to resume their negotiations in Istanbul, Turkey, on April 14 and in case of good progress hold a second round of talks in Iraq's capital city, Baghdad.
The last meeting between the two sides took place in Istanbul in January 2011. Iran and the G5+1 had also held two rounds of multifaceted talks in Geneva in December 2010.
The Iranian team of negotiators is led by Supreme National Security Council (SNSC) Secretary Saeed Jalili, while delegations of the six world powers are headed by EU foreign policy Chief Catherine Ashton.
