"The negotiations have already intensified, as we said that they would, and they will continue to do so in the days and weeks leading up to July 20. I cannot imagine that between now and July 20, we will not in some form or fashion be meeting every single day in one way or another," a Senior State Department official told reporters.
The P5+1 term refers to the P5 or five permanent members of the UN Security Council, namely the US, Russia, China, the UK, and France, plus Germany.
"Our focus is to make as much progress as possible, and of course to reach an agreement by the 20th of July," the official said on the condition of anonymity.
Noting that the focus is on July 20, the official said: "I think everyone in the P5+1 agrees and I think Iran agrees that it is not in anyone's interest to decide today that an extension is warranted. We can get this done. It is possible to get it done. We should be focused on getting it.
"I think that it's most worthwhile for all of us to focus on the hard work necessary to get an agreement by July 20th that is in Iran's best interest. But looking from the outside, it would seem to me it would be in their best interest to do so, and it's certainly in the interest of the international community that we are sure that Iran cannot obtain a nuclear weapon and that its programme is exclusively peaceful," the official said in response to a question.
