On September 16, 2007, Iranian Foreign Minister Manouchehr Mottaki announced the completion of the Bushehr Nuclear Power Plant, adding that it was "sealed by the UN nuclear watchdog, International Atomic Energy Agency (IAEA)". On September 20, Reza Aqazadeh, the head of Iran's Atomic Energy Organization, in reference to his talks with Sergei Kiriyenko, the director of Russia's Federal Atomic Energy Agency in Vienna, said that they "discussed the pending issues of the Bushehr Nuclear Power Plant".

Russia's concern over Iran's nuclear programme is increasing with every passing day. Iranian authorities are showing un-willingness to accept Russia's proposal to enrich uranium in Russian territory. Russia is trying to resolve an international crisis over Iran's suspected nuclear weapons programme, though its position on Iran has rhetorically moved closer to the European "Troika" (France, Germany, UK). Russia agreed to Iran's referral to the UN Security Council on the condition that the council would take action only after the March 6 IAEA meeting.
