"We are working hard at different levels to see how we can obtain results and we hope that some progress will be made during the opportunities that will arise in the next few days, but this depends on the other side's approach," Araqchi told reporters in New York on Friday.
Asked about the key differences between the Iranian and the Group 5+1 negotiators, he said the two sides have differences over Iran's enrichment program and its capacity, removal of the sanctions against Tehran which should all be annulled based on the Geneva agreement inked in November, Arak heavy water reactor and Fordo uranium enrichment facility.
Araqchi expressed the hope that the presence of the lead negotiators of Iran and the G5+1 in the negotiations underway in New York would help the talks make tangible progress.
He also dismissed talks with the US officials on issues other than the nuclear case, and said, "We haven’t talked and negotiated with the Americans on the Islamic State of Iraq and the Levant (ISIL), Iraq or anything other than the nuclear issue."
In relevant remarks on Wednesday, Iranian Foreign Minister Mohammad Javad Zarif said goodwill on the part of the six world powers in their talks with Tehran would lead to a permanent settlement of the decade-long nuclear crisis between the two sides.
"We have always said in our negotiations with the other side that if they show mutual respect and goodwill reaching a final and comprehensive agreement can easily be achieved," Zarif told reporters after his meeting with EU foreign policy chief Catherine Ashton in New York on Wednesday.
He noted that he held over three hours of talks with the EU foreign policy chief in New York.
Zarif left Tehran for New York on Tuesday morning to participate in the next round of nuclear talks between Iran and the six major world powers on the sidelines of the UN General Assembly meeting.
On September 1, Zarif and Ashton met in Brussels, Belgium, to discuss the process of the ongoing nuclear talks.
Last November, the two sides signed an interim deal in Geneva, which took effect on January 20 and expired six months later on July 20. In July, Tehran and the six countries agreed to extend negotiations until November 24 after they failed to reach an agreement on a number of key issues.
Iranian President Hassan Rouhani is also in New York to participate the world body gathering and is due to meet several high-ranking officials of the world countries, including the G5+1 members.
