After three days of talks in Vienna between world powers and Iran over it's nuclear program, Iran has said the talks have concluded with an agreement on a framework for negotiations on a comprehensive deal.
The atmosphere at the talks was described as positive by Iran's Deputy Foreign Minister Abbas Araqchi.
Catherine Ashton, the European Union Foreign Policy Chief, said representatives from both sides identified issues that need to be resolved.
No doubt there is still much more ahead – with difficult challenges, but the parties are building confidence to move from the interim agreement we are currently in to a permanent one.
So far we have seen Iran reduce it's uranium enrichment (the lowest level in four years according to some reports, for the sanctions relief.
At stake here is a nuclear Iran, which it says it is not interested in.
The world powers want Iran to scale back its sensitive nuclear activities permanently to ensure that it cannot assemble a nuclear weapon.
It also says its nuclear work will continue, and wants an end to the sanctions that have hurt the average Iranian and his country's economy.
Lets be clear, no one is optimistic at present and more talks are set to follow.
From the World Powers point of view the current talks were productive.
The next round of talks will take place, again in Vienna on March 17th, and that technical experts had also begun discussions.
The sides have given themselves six months to negotiate a comprehensive permanent solution, although that deadline will probably not be met and thus can be extended.
