The text, delivered to Iran on June 6 but kept secret, calls for a moratorium on enrichment until the UN atomic agency verifies "that all outstanding issues and concerns reported by the IAEA, including those activities which could have a military nuclear dimension, have been resolved."
European Union foreign policy chief Javier Solana handed over the text, which offers substantial trade, security and technology incentives to Tehran, to Iran's top national security official, Ali Larijani.
Previous media reports had suggested that the text had called for a suspension on enrichment only for the duration of talks on the benefits package. The text did not include a list of sanctions to be imposed if Iran failed to comply.
