At a joint press conference with Armenian Foreign Minister Edward Nalbandian in Yerevan on Tuesday, Foreign Minister Mohammad Javad Zarif said these countries should be aware that they could hold talks with no countries while simultaneously putting pressure on them.
He said working out a solution is going to benefit all especially the regional countries.
Pointing out that discussions during nuclear negotiations with the sextet are now focusing on expert details, the Iranian foreign minister said the other parties have already accepted Iran's right to continue its enrichment activities.
Noting that Iran has never intended to develop nuclear weapons, he stated Tehran is ready to offer necessary proofs about the peaceful nature of its nuclear activities to a limited numbers of countries which doubt it.
The FM said the existing differences on details could be removed by the political will of negotiating parties.
Zarif arrived in the Armenian capital on Monday heading an Iranian delegation.
The 2-day visit is upon invitation of Armenian Foreign Minister Edward Nalbandian.
