Clinton: Iran must take ‘concrete steps’ in nuclear discussions

ISTANBUL — U.S. Secretary of State Hillary Rodham Clinton says Iran must be prepared to take “concrete steps” when it discusses its nuclear program with world powers in Moscow later this month.

Clinton says one of the main concerns is Iran’s 20 percent enriched uranium, which the West and others say is close to being boosted to weapons-grade material. She said in Istanbul on Thursday that the goal of the June 18-19 talks is to begin the work necessary for a diplomatic solution, and that the six-nation bloc negotiating with Iran is prepared to take steps of its own.

The bloc includes the five permanent U.N. Security Council members and Germany.

Previous talks have yielded few tangible accomplishments. Iran insists it has no intention of making nuclear arms.
