A member of Iranian nuclear negotiating team said Additional Protocol is a part of the last step presented in Iran's nuclear plan, ISNA news agency reported.
"None of these topics is not in the first step of Iran's proposal, but it is part of the last step of the offer," Abbas Araqchi told reporters in Geneva as asked whether Iran would discuss enrichment and administration of Additional Protocol with G5+1.
Asked about progress in talks between Iran and representatives of the 5 permanent members of the UN Security Council plus Germany, he said, "It is early to judge and say we made progress in making views closer. We will hear their views and if there is any interaction in our views we can say we can take step forward."
Araqchi also called the talks 'serious' held in 'positive atmosphere', and said both sides are avoiding raising any controversial issue.
He said the tone and language of the other side seems to be more positive, but no change in approach has been seen yet.
Elsewhere, regarding Iran's plan, he said Iran has submitted a plan or proposal not a package and the plan is flexible to changes.
Araqchi called the proposal 'confidential' and refused to give further details.
Iran submitted its package titled 'closing an unnecessary crisis, opening new horizons' in the new round of talks underway in Geneva and started on Tuesday.
