UNITED NATIONS (AP) — Nuclear experts from Iran and six world powers are meeting in New York this week amid rising hopes that an agreement can be reached to limit Iran's ability to produce nuclear weapons before a July 20 deadline.
The toughest issues must still be negotiated, and any deal could still fall apart.
But Russia, the International Atomic Energy Agency and outside experts tracking the negotiations agree that the Iranians are cooperating, answering questions that they previously avoided and appear to want an agreement that ends crippling sanctions.
Hopes for a deal were bolstered by news that international nuclear inspectors plan to visit two sites in Iran in the coming days, which an official said Sunday would fulfill demands made by the United Nations nuclear watchdog. A report by Iran's official IRNA news agency quoted Behrouz Kamalvandi, spokesman of Iran's atomic department, as saying the inspectors will visit a uranium mine and a uranium-thickening facility in central Iranian towns of Ardakan and Yazd on Monday and Tuesday.
Daryl Kimball, executive director of the Washington-based Arms Control Association, stressed that negotiators have said repeatedly there's no agreement until all outstanding issues are resolved. But he said he remains optimistic.
"We see encouraging signs that both sides are showing flexibility and pragmatism that is necessary to put together the final package," he said.
Iran insists its nuclear program is peaceful, aimed at producing nuclear energy, but the U.S., its Western allies and Israel have long believed Tehran's real aim is producing nuclear weapons.
The experts are meeting in New York this week to prepare for the next ministerial-level negotiations in Vienna on May 13.
Their closed-door sessions, starting Monday, are taking place on the sidelines of the third and final preparatory conference for next year's review of the landmark 1970 Nuclear Nonproliferation Treaty, a pact aimed at stopping the spread of nuclear weapons.
Patricia Lewis, former head of the United Nations Institute for Disarmament Research who now directs research on international security at London's Royal Institute of International Affairs, said "there's been a big change" in Iran's approach compared to two years ago, "when it was just constant stalemate" on efforts to rein in its nuclear program.
"There has been real moving ahead and real genuine progress in what they've been trying to achieve," she said. "They're small steps, but they're significant steps. I would say, so far, so good. I'm holding my breath."
The change in Iran was sparked by the election of centrist President Hasan Rouhani, who replaced hard-liner Mahmoud Ahmadinejad in June 2013. Rouhani pledged to reduce confrontation with the international community over its nuclear activities, and agreed to restart stalled negotiations with the six powers in November.
That agreement with the U.S., Russia, China, Britain, France and Germany requires Iran to stop enrichment of uranium to 20 percent — which is a possible pathway to nuclear arms — in exchange for the easing of some Western sanctions.
The two sides are working toward a permanent agreement by July 20 that would cap Iran's enrichment program, reduce its stockpile of 20 percent enriched uranium and turn some of it into a solid form which is less usable in bomb-making, and curb other atomic activities in exchange for lifting all sanctions.
The November agreement also agreed to allow the U.N. nuclear watchdog, the International Atomic Energy Agency, to visit its nuclear facilities.
When the last round of high-level negotiations ended on April 9, Iranian Foreign Minister Mohammad Javad Zarif said his country and the six powers were in "50 to 60 percent agreement" on the shape of a deal.
