Iranian President Hassan Rouhani stressed that negotiation was the only way to final settlement of Iran's nuclear issue.
Rouhani made the remarks in a meeting with the newly-appointed accredited ambassador of Iceland to Tehran Gonar Pulsen who had called on him to submit his credentials, Iran's official IRNA news agency reported on July 22.
Iran is optimistic about the success of the talks, Rouhani said, adding that the Iranian nation was only after safeguarding its inalienable nuclear rights.
Iran and the five permanent members of the UN Security Council- the US, France, Britain, Russia and China - plus Germany have agreed on the extension of talks until November 24 with a view to achieving a permanent deal that would end the decade-old dispute over Iran's nuclear energy program.
President Rouhani voiced readiness for cooperation with Iceland within the frameworks of international regulations.
He further termed cooperation among world nations and governments as necessary for tackling international problems.
