With no immediate prospect of sanctions relief for Iran, and no solid progress in negotiations with the West over the country's nuclear programme, Ciara Lee asks why talks have still not produced results and what a resolution would mean for both parties.
Six world powers may have failed to resolve their 12-year confrontation with Iran over its nuclear ambitions, but the mood in Tehran was upbeat. (SOUNDBITE) (Farsi) TEHRAN RESIDENT, JALALI, SAYING: "Mister Zarif and Mister Rouhani can see all our offers and decide themselves. I don't think it will take much longer." . (SOUNDBITE) (Farsi) RETIRED RESIDENT IN TEHRAN, ALI AKBAR SIGARCHI, SAYING: "If a comprehensive agreement is reached it would be really good. We must have cooperation with the world, we must have good relations with the world." The United States, France and Germany, along with Russia, China and Britain - are trying to reach a deal to limit Tehran's nuclear capabilities President Rouhani won the election last year on promises to end Iran's international isolation. Patching up relations with the West could help stop international sanctions. They've crippled the economy and reduced Iran's oil output. Neil Atkinson is head of analysis at Lloyd's List Intelligence. (SOUNDBITE) (English) NEIL ATKINSON, HEAD OF ANALYSIS AT LLOYD'S LIST INTELLIGENCE, SAYING: "It's got a million barrels a day of export capacity shut in and the oil that it is able to sell, is selling 25 dollars a barrel than was the case a few months ago. And of course it has wider economic problems, inflation is very high in Iran, the lack of access to foreign currency because of a lack of oil sales is impeding the ability of the economy to operate in many sectors. Iran desperately needs a deal and it desperately needs to get its oil back in the market place." Talks are set to resume next month, but there could be a spanner in the works Iran's Supreme Leader Ayatollah Ali Khamenei isn't happy. (SOUNDBITE) (Farsi) IRANIAN SUPREME LEADER AYATOLLAH ALI KHAMENEI, SAYING: "America and the former European colonial powers have come together and used all in their power to bring the Islamic Republic to its knees over the nuclear issue. But they haven't been able to do this and never will.." . A Twitter account thought to be run by Khamenei's officials has even described Western powers as "arrogant". They've now given themselves seven more months to overcome the deadlock.
