“Mr. Rohani has appointed a group to examine the continuation of talks with the P5+1 (permanent members of the UN Security Council plus Germany) and our friends in the Foreign Ministry are cooperating with him,” said Iranian Foreign Minister Ali Akbar Salehi in a joint press conference with his visiting Tajik counterpart, Hamrokhon Zarifi, in Tehran on Wednesday.

Salehi noted that since the Iranian administration is in the transition process, it is not easy to hold talks with the P5+1 at present time, and the concerned parties should wait for at least two to three weeks.

“The time and venue for the next round of talks will be determined when Mr. Rohani takes office,” he added.

Rohani emerged victorious in Iran’s 11th presidential election in June 14, which was marked by a high voter turnout, winning 50.7 percent of a total of over 36 million ballots counted. The voter turnout in the election was 72.7 percent, according to Iran’s Interior Ministry.

He had earlier called for serious talks between the two sides to make practical improvements, calling on the West to turn toward “serious and real negotiations instead of pressure” for making progress.

“Negotiations should reach to agreements, but it hasn’t been achieved till today,” Rohani said.

Rohani was Iran’s chief nuclear negotiator from October 2003 to August 2005.

Iran and the P5+1 have held several rounds of talks on a range of issues with the main focus being on Iran's nuclear energy program.
