Iran's President Hasan Rouhani has said that Iran can strike a "win-win" deal with world powers over its nuclear programme, but that time is limited to reach an agreement.
In a statement carried by state TV on Tuesday, Rouhani said Iran is "ready for the win-win game", but added: "The world should know that the period for solving the nuclear case will not be unlimited."
"The world should take advantage of this period and the opportunity that our nation created in [my] election."
The West is hoping that Rouhani will take a more constructive approach in long-running talks on Iran's controversial nuclear drive, which despite Iranian denials is suspected by world powers of having military objectives.
Rouhani has stressed a more diplomatic approach to foreign affairs than the style of his predecessor, Mahmoud Ahmadinejad.
But Rouhani has also insisted that Iran would not make concessions on the pillars of its nuclear programme such as uranium enrichment.
Iran "will not withdraw an iota from the definite rights of people",' Rouhani was quoted by the state news agency IRNA as saying on Tuesday.
Enriching uranium is the core issue at the centre of the nuclear controversy and a potential pathway to atomic weapons.
