If Iran is serious about taking practical steps to address the international community’s deep concerns about its nuclear program, we will continue to engage both multilaterally and bilaterally to discuss the full range of issues that have divided Iran and the United States for too long.

The door is open to a better future for Iran. But the process of engagement cannot be open-ended. We are not prepared to talk just for the sake of talking. As President Obama noted after the October 1st meeting in Geneva, we appear to have made a constructive beginning. But that needs to be followed up by constructive actions.

In particular, prompt action is needed on implementing the plan to use Iran’s own low-enriched uranium to refuel the Tehran research reactor, which is used to produce medical isotopes.
