Iran is ready to show more transparency on its nuclear programme, says President-elect Hassan Rouhani.
In his first news conference since Friday's vote, Mr Rouhani also described as unfair sanctions imposed on the country over the issue.
And he said Tehran would not suspend its uranium enrichment activities.
The West suspects Iran of trying to build nuclear weapons. Tehran says its programme is solely for peaceful purposes.
At the news conference, which covered a wide range of issues, Mr Rouhani also said his government would work towards "constructive interaction with the world".
