"Cairo has always welcomed in principle anything that can help to sustain stability in the Middle East," but "nothing definite has been decided yet" about hosting the talks, the official Egyptian MENA news agency quoted a diplomat as saying on Thursday.
"Contacts are under way on this issue," the diplomat added.
On Wednesday, Iran proposed Cairo as the venue for the next talks with the five permanent UN Security Council members -- Britain, China, France, Russia and the United States, plus Germany, known collectively as the P5+1.
Iranian Foreign Minister Ali Akbar Salehi said that Cairo had welcomed the idea of hosting the talks.
Iran and the P5+1 group have held several rounds of talks with the main focus being on Iran’s nuclear energy program. The last round of negotiations between Iran and the P5+1 was held in Moscow in June, 2012.
The United States, Israel and some of their allies accuse Iran of pursuing non-civilian objectives in its nuclear energy program.
Iran has vehemently rejected the allegation, arguing that as a committed signatory to the Non-Proliferation Treaty and a member of the IAEA, it is entitled to develop and acquire 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 its civilian nuclear program has been diverted toward military purposes.
