WASHINGTON - The United States is ready to engage in talks "on the basis of mutual respect" with Iran about its disputed nuclear programme as long as Tehran is willing to demonstrate that its programme is for civilian purposes, the White House said on Friday.
"We have had a number of engagements with the Iranians and we'll continue to have conversations on the basis of mutual respect," Josh Earnest, the deputy White House spokesman, told reporters aboard Air Force One during President Barack Obama's flight earlier in the day to Missouri.
"And over the course of those conversations there will be an opportunity for the Iranians to demonstrate through actions the seriousness with which they are pursuing this endeavour," Earnest said.
Obama and Iranian President Hassan Rouhani will be in New York next week for a meeting of the United Nations General Assembly. The White House has said that an encounter between the two leaders is possible.
Earnest said there was no meeting scheduled between Obama and Rouhani, but his comments were the latest signal from the White House that it views Rouhani potentially as someone with whom it can do business.
Western powers believe Iran is developing nuclear weapons. Tehran says its nuclear programme is peaceful and aimed at power generation.
The positive tone in US-Iranian relations, which have been fraught since the 1979 Iranian Revolution, worries Israel. It is warning the Obama administration not to be seduced by Rouhani's charm offensive.
A senior Israeli minister said on Friday that Iran is on course to develop a nuclear bomb within six months and time has run out for further negotiations.
But in a call with reporters to preview Obama's UN speech, deputy national security adviser Ben Rhodes said Washington believed there was time to pursue diplomacy with Iran.
"We've always made clear that there's not an open-ended window for diplomacy, that we need to be moving forward with a sense of urgency," Rhodes said.
"We do believe ... that Iran has not taken steps, for instance, to break out and weaponize its nuclear programme. So even as we move with a sense of urgency here, we do believe that there's time and space to pursue diplomacy."
The New York Times reported on Friday that Iran is seeking a "swift agreement" over its nuclear programme with the goal of ending sanctions that have devastated its economy.
Earnest, responding to that story, said the White House welcomed the new tone from Tehran after Rouhani's election in June and said sanctions had had their desired effect.
"These sanctions have tightened around the Iranian regime, further isolated them from the international community, taken a significant toll on their economy and put pressure on them to come back to the bargaining table," he said.
"The president has demonstrated a willingness to engage with the Iranians, and has done that for some time now," he added, noting that Obama and Rouhani had exchanged letters.
