Mohammad Javad Zarif said at today's news conference in Tehran that the US wanted Iran to give up major parts of its program, but "those wishes are unlikely to come true and that's why they are negotiating with the Islamic Republic of Iran to achieve a solution based on realities."
Iran stopped enrichment of uranium to 20 per cent and started neutralising its stockpile on January 20 in order to fulfil commitments reached under an interim deal in Geneva on November 24. Negotiations over a final comprehensive deal are to start February 18.
