The foreign ministry spokesperson said Iran will not sign any final nuclear deal before ensuring that its considerations are fully recognized by the major powers in the negotiations with Tehran to settle the dispute over its nuclear program.
The powers in talks with Iran include the United States, Britain, France, Germany, Russia and China, together known as the P5+1.
"There will be no agreement until the issues of concern to the Islamic Republic have been fully addressed and concluded," Marzieh Afkham said on Thursday, ISNA reported.
She added, "Iran has specifically and transparently expressed its positions regarding every aspect of the negotiations from the beginning."
She made the remarks in response to the recent comments by her US counterpart that the prospective deal would be unlikely if Iran did not undertake to provide access to its military sites for inspection and to its nuclear scientists for interview.
Asked whether the differences on the issue of questioning Iranian scientists could "undo the whole deal or the whole process," State Department spokesperson Marie Harf said during a daily press briefing on Thursday that, "well, as I said – and we've said a number of times since Lausanne – we and the Iranians agreed to undertake a process to develop a list for access in terms of the PMD (possible military dimensions of Iran's nuclear program) issue."
"The people and places on that list are an ongoing topic of conversation, but we will not agree to any final agreement that doesn't meet what we need to get out of that piece of it," she said, according to a transcript of her remarks posted on the website of the US State Department.
Her remarks came after Leader of the Islamic Revolution Ayatollah Seyyed Ali Khamenei again rejected the demands as "excessive" on Wednesday.
"As we have said before, we will grant no access to any of our military centers and (allow) no interview with our nuclear scientists," Ayatollah Khamenei said, adding, "We will not let outsiders interrogate our scientists… over a fundamentally indigenous achievement," which is a national concern.
Iran denies its nuclear work may have any military objectives, saying the program is meant only for peaceful applications.
