"Given the Islamic Republic of Iran's capabilities in the field of peaceful nuclear technology, the US should respect the international rules, the NPT and the Iranian nation's rights," Chairman of the parliament's National Security and Foreign Policy Commission Alaeddin Boroujerdi said Saturday.
He underlined that since Iran is an NPT member, the western states should respect the country's right to use the civlian nuclear technology.
"The West should also avoid raising excessive demands in order to reach results (in talks between Tehran and the world powers)," Boroujerdi said.
Senior diplomats of Iran and the six world powers ended another round of talks in Vienna on Friday.
The Iranian negotiators had several rounds of bilateral talks with the delegations of the EU and the Group 5+1 Group 5+1 (the US, Russia, China, Britain and France plus Germany), including a rather lengthy meeting with the US team, during their three-day-long talks in the Austrian capital.
A senior diplomat close to the Iranian team of negotiators in the Vienna nuclear talks with the world powers urged the Western states to stop their excessive demands, reiterating that Iran is standing firm on its rights.
"The West should give up its excessive demands and gather a precise assessment of the realities existing on the ground," the diplomat told FNA in Vienna on Friday afternoon, stressing that the policy of pressuring Iran has always proved futile and backfired.
The source said the Iranian negotiators have come to Vienna to establish the nation's rights, reiterating that they would never retreat along this path.
He said "difference in views, specially around such a vital discussion as Iran's nuclear issue, is considered to be natural", but "given the recent developments, the western states are displaying that they are not practicing the pragmatism that seemed to have developed in them to a certain level".
Yet, the diplomat underlined that "the window of opportunity is still open for the western parties to step onto the realm of pragmatism".
