Iranian Foreign Minister Ali-Akbar Salehi has expressed hope that Iran and the International Atomic Energy Agency (IAEA) could reach an agreement on a new modality to resolve remaining issues concerning Iran's nuclear activities.

Salehi said that Iran and the IAEA would discuss the issue of modality and a new framework to remove the IAEA's ambiguities and questions over some aspects of the country's nuclear program during the Sunday visit of the IAEA Director General Yukiya Amano to Iran, the semi-official ISNA news agency reported on Saturday.

Iran's envoy to the IAEA Ali-Asghar Soltanieh confirmed on Friday the reports that Amano will visit Iran on Sunday, the semi- official Mehr news agency reported.

Soltanieh told Mehr that Amano is visiting Tehran for talks with Iranian officials on "issues of mutual interest and a closer cooperation" between Iran and the IAEA.

Salehi said that "the IAEA delegation does not seek inspections (into the country's nuclear sites) in the trip" to Tehran, adding that "the trip of the IAEA director general to Iran occurs due to his interest," according to ISNA.

Iran had already invited the IAEA chief to visit the country, but he preferred to travel to Tehran ahead of Baghdad talks, said Salehi.

The world powers and Iran will hold next round of nuclear talks in Iraqi capital Baghdad on May 23.
