Kerry praises Iran's 'very different tone' after historic meeting

“We've agreed to try to continue a process that would try to make concrete and find a way to answer the questions that people have about Iran's nuclear program,” Kerry told reporters after the meeting, according to Iran's Press TV.

“Needless to say, one meeting and a change in tone, that was welcome, does not answer those questions,” he said. “All of us were pleased that the foreign minister came today and that he did put some possibilities on the table.”

The negotiators – the United States, China, Russia, France, Great Britain and Germany – agreed to hold a new round of talks with Iran on Oct. 15 and 16 in Geneva. Iran continues to insist its program is for peaceful purposes but its new president, Hassan Rouhani, has indicated that he is willing to negotiate with the United States and the rest of the international community.

The meeting between the top American and Iranian diplomats was the highest-level encounter of substance meeting between the two countries since the 1979 revolution. Secretary of State Madeleine Albright sat in a room with her Iranian counterpart in 2000 during multi-national conversations at the UN about Afghanistan, but the two did not speak directly.
