Tehran - No date has yet been fixed for the visit by European Union foreign policy chief Javier Solana to Tehran, Iranian Foreign Ministry Spokesman Mohammad-Ali Hosseini said Monday.

The spokesman told reporters in Tehran that talks were being held for a visit by Solana and representatives of the five UN veto powers plus Germany (5+1) in order to give an upgraded incentive to the Iranian government.

Hosseini was referring to an offer by the 5+1 aimed at persuading Iran to suspend uranium enrichment activities.

There had been reports that Solana and deputy foreign ministers of the 5+1 would come to Tehran to present the package to Iranian Foreign Minister Manouchehr Mottaki.

Only Washington said that it would not send any envoy to the Islamic state.

The spokesman said that the exact date of the visit was yet to be fixed.

Iranian President Mahmoud Ahmadinejad said last week that Western incentives would not stop Iran's nuclear projects, including uranium enrichment, but noted that Iran would nevertheless evaluate the package.

Referring to remarks by Russian Foreign Minister Sergei Lavrov last week that the 5+1 should offer Iran security guarantees, Hosseini said that Iran would not need such guarantees and never demanded any.

The spokesman added that Iran had in return forwarded its own package to the Western states and hoped that Iran's initiative would prepare the ground for constructive talks between Iran and the 5+1.

Hosseini rejected reports that the proposals would be the same as put by Ahmadinejad in letters to Western heads of states, including US President George W Bush, German Chancellor Angela Merkel and even to Pope Benedict XVI.

Ahmadinejad's letters, containing a call for a return to spirituality and stopping support for Israel, were at that time ignored by the Western leaders and remained without reply.

The Iranian package was last week sent by Mottaki to UN Secretary General Ban Ki-moon and a copy of it to the foreign ministers of the five permanent member states of the UN Security Council.

Another copy was sent to Solana.

While guaranteeing the peaceful nature of Iran's nuclear projects and readiness to hold talks with the 5+1, Mottaki once again rejected in the package the main Western demand of a suspension of uranium enrichment.

Mottaki further criticized the UN for allegedly ignoring reports by nuclear watchdog IAEA on Iran's nuclear programmes and instead referring the dossier to the Security Council, which eventually led to three resolutions and financial sanctions against Tehran. (dpa)
