"Iran will enter tomorrow's negotiations with clear and instrumental proposals,” said on Thursday Ali Baqeri, who is accompanying Iran’s negotiation delegation in the Kazakh city of Almaty.

The Iranian official stressed that any proposal by P5+1 in the talks should take into consideration the recognition of Iran's right to use of nuclear energy program.

The Islamic Republic and the P5+1 group will hold two days of negotiations in the Kazak city on April 5 and 6, with the main focus being on Iran’s nuclear energy program.

Earlier in the day, SNSC secretary and Iran's chief nuclear negotiator Saeed Jalili defended Iran’s rights to use nuclear energy for civilian purposes and said recognition of Iran’s right to achieve nuclear technology by the P5+1 would start a new chapter in the talks.

The US, Israel and some of their allies claim that Iran is pursuing non-civilian objectives in its nuclear energy program, with the US and the European Union using the false claim as pretext to impose illegal sanctions against Iran.

Tehran rejects the allegation over its nuclear energy activities, maintaining that as a committed signatory to the NPT and a member of the International Atomic Energy Agency, it has the right to use nuclear technology for peaceful purposes.
