Britain, France and Germany have called for the UN's nuclear watchdog, the International Atomic Energy Agency, to meet at the beginning of February.
The announcement was made by the British Foreign Office after a meeting of international diplomats in London to discuss Iran's controversial nuclear programme.
Meanwhile, the EU foreign policy chief, Javier Solana, has said he is confident that China and Russia will back the EU in seeking a referral of Iran's nuclear programme to the UNSC.
Iran has insisted its nuclear programme is for producing electricity, not weapons.
Earlier, the British Foreign Secretary, Jack Straw, warned against rushing to impose sanctions on Iran.
Tehran has said that the international condemnation is being orchestrated by a few Western countries.
Saudi Arabia has also criticised the West while continuing to oppose Iran's development of nuclear weapons.
However, the head of the IAEA, Mohamed El Baradei, says that despite three years of intensive work he cannot confirm that Iran's nuclear programme has a solely peaceful objective.
He said that the IAEA needed further access to documents, people and locations in Iran.
Over the weekend Iran issued a sharp warning that sanctions could simply drive up world oil prices.
