The spokesman for the Iranian Parliament’s National Security and Foreign Policy Committee said that the latest round of nuclear negotiations revealed “intense disagreements” over a variety of issues, including enrichment, Iran’s missiles and even the proposed methods of lifting sanctions, which would take into consideration human rights issues.

In what was described as the first part of a series of long interviews, Seyed Hossein Naghavi Hosseini spoke to Tasnim News Agency about the progress of the latest nuclear talks. The Iranian negotiators spent last week in Vienna with the five permanent members of the UN Security Council plus Germany (P5+1) to begin the drafting process of a final nuclear deal. After previous negotiations, the Iranian team reported to the National Security and Foreign Policy Committee, but is not clear whether it has this time around.

Naghavi Hosseini said that one of the points of contention was that “The West discussed our defense systems and our missiles, while from the beginning we said that this is not negotiable, but they are still insisting on this point.”

He added that another difference, “The West has issues with the number and quality of our centrifuges and even has issues with the number of centrifuges at each site. … The West even has problems with our research and development.”
