"We share your concerns... of Iran's actions in other areas. That is precisely why we are vigorously implementing sanctions."

"I think one of the most powerful things that happened in Iran in recent years was actually the election of President Rouhani."

"We agree that R&D has to be a critical component of any agreement."

"So far from being able to implement additional sanctions, we would be unable probably to implement the existing sanctions regime."
