Secretary of Iran's Supreme National Security Council Saeed Jalili says the Islamic Republic has agreed to resume talks with six major world powers about the country's nuclear energy program this month, Press TV reported.
"We have agreed to hold talks [with the P5+1] planned for January, but no agreement has been reached on the date and venue," Iran's chief nuclear negotiator told reporters in New Delhi on Friday.
"We welcome their return to talks and we hope that they would enter talks with a constructive approach and would not repeat their previous miscalculations," he said.
Jalili called on the P5+1 group -- Britain, China, France, Russia and the United States plus Germany -- to keep in mind that Tehran would continue to determinedly defend the Iranian nation's right to peaceful nuclear technology.
Meanwhile, the European Union (EU) announced on Friday that nuclear talks with Iran would resume "very soon".
"They're negotiating the modalities and the details for the next round to be held very soon," Sebastien Brabant, a spokesman for EU foreign policy chief Catherine Ashton, who heads the P5+1 group's delegation, said in Brussels.
Iran and the six major world powers have held several rounds of talks with the main focus being Iran's nuclear energy program.
The United States, Israel and some of their allies have repeatedly accused Iran of pursuing non-civilian objectives in its nuclear energy program.
Iran rejects the allegations, arguing that as a committed signatory to the nuclear Non-Proliferation Treaty (NPT) and a member of the International Atomic Energy Agency (IAEA), it has the right to use nuclear technology for peaceful purposes.
In addition, the IAEA has conducted numerous inspections of Iran's nuclear facilities but has never found any evidence showing that Iran's civilian nuclear program has been diverted to nuclear weapons production.
