Talks between Iran, the five permanent members of the U.N. Security Council and Germany concluded after two days in Kazakhstan.
U.N. weapons inspectors this year said there weren't able to gain access to military compounds in Iran to confirm the country's peaceful intent. Iran is suspected of pursuing the technology needed to produce a nuclear weapon, an allegation it denies.
British Foreign Secretary William Hague confirmed Wednesday from London that negotiators agreed to another round of talks in Istanbul beginning March 18 to discuss the details of this week's confidence-building measures.
Iran, he said, needs to come forward with signs of its peaceful intentions given the latest concerns from the International Atomic Energy Agency.
"Iran has much to gain from a diplomatic resolution to the nuclear issue and we are clear on the need for talks to deliver results," Hague said in a statement.
He provided few details of proposals, other than to say they're meant to give both sides a level of confidence. Iran's nuclear negotiator Saeed Jalili was quoted by Iranian broadcaster Press TV as describing the Almaty talks as "positive."
