Iranian Foreign Minister Mohammad Javad Zarif said Thursday it was possible to reach a deal with world powers on Tehran's nuclear program by the end of talks in Geneva on Friday.

"I believe it is possible to reach an understanding or an agreement before we close these negotiations tomorrow evening," Zarif told CNN after a first day of talks between Iran and six world powers.

He said Tehran was "prepared to address the most immediate concerns" about its nuclear program but insisted it would not fully give up enrichment.

"There won't be a suspension of our enrichment in its entirety but we can deal with the various issues on the table," he said.

He said there had been agreement at the talks on a framework for the deal and that Friday could see the drafting of a joint statement.

"Now we know what the ingredients should be... and I think our colleagues are ready to start drafting," Zarif said.

"I hope that by tomorrow morning we can start serious work in order to prepare some kind of joint statement."

He refused to go into specifics, saying: "We are at a very sensitive stage of negotiations and it's best if these negotiations are done at the negotiating table."

Iranian Deputy Foreign Minister and Senior Negotiator in talks with the world powers Sayyed Abbas Araqchi announced that Tehran and the Group 5+1 (the permanent UN Security Council members plus Germany) will continue their negotiations on Friday.

“The negotiations will continue on Friday. Various and complicated issues are on the negotiating table and reaching an agreement is not an easy job and we hope that we can have good progress today and tomorrow,” Araqchi told reporters in Geneva after participating in the first session of the talks with his G5+1 counterparts in a fresh round of negotiations on Thursday.

Noting that the two sides have many differences, he said, “Bringing the viewpoints close to each other is not an easy job and it is still too early for an assessment.”

“We can say that we are in a good and positive situation but we should wait to see at what speed the viewpoints come close to each other,” Araqchi said.

 He said that there will possibly be more talks between Iran and the six world powers in future, adding that Geneva will likely be the host to those talks as well.

Asked about the media reports about the suspension of Iran’s nuclear enrichment program for 6 months, Araqchi said, “Enrichment is important to us and is our redline.”

Elaborating on the meetings due to be held after the first session of the Thursday talks between Iran and the world powers, he said, “The Iranian team is due to hold separate negotiations with the Chinese, European, Russian and the US teams.”
