Iran
has said an oil embargo adopted by European Union foreign ministers
over the country's nuclear programme is "unfair" and "doomed to fail".
The measures would not prevent Iran's "progress for achieving
its basic rights", foreign ministry spokesman Ramin Mehmanparast said.
The sanctions ban all new oil contracts with Iran and freeze the assets of Iran's central bank in the EU.
The EU currently buys about 20% of Iran's oil exports.
"European officials and other countries which are under
America's political pressure... should consider their national interests
and not deprive themselves of Iran's oil to help US officials achieve
their secret aims," Mr Mehmanparast added.
He accused the US of trying to create "problems with energy
supply requirements in countries which are America's economic rivals".
Warships on the move
The sanctions were formally adopted at a meeting of EU foreign ministers in Brussels on Monday.
Iran had "failed to restore international confidence in the
exclusively peaceful nature of its nuclear programme", British Prime
Minister David Cameron, French President Nicolas Sarkozy and German
Chancellor Angela Merkel said in a joint statement.
"We will not accept Iran acquiring a nuclear weapon. Iran has
so far had no regard for its international obligations and is already
exporting and threatening violence around its region," the leaders
added.
The measures were "another strong step in the international
effort to dramatically increase the pressure on Iran", US Treasury
Secretary Timothy Geithner and Secretary of State Hillary Clinton said
in a statement.
Meanwhile, the International Atomic Energy Agency, the UN's
nuclear watchdog has confirmed it is sending a team to Iran between 29
and 31 January "to resolve all outstanding substantive issues".
Last November the IAEA said in a report that it had
information suggesting Iran had carried out tests "relevant to the
development of a nuclear explosive device".
Tehran insists its nuclear programme is for energy purposes.
Earlier on Monday, the Pentagon said the US aircraft carrier
USS Abraham Lincoln, as well as a British Royal Navy frigate and a
French warship, had passed through the Strait of Hormuz at the entrance
to the Gulf without incident, following Iranian threats to block the
trade route.
Russian opposition
The EU said the sanctions prohibit the import, purchase and
transport of Iranian crude oil and petroleum products as well as related
finance and insurance. All existing contracts will have to be phased
out by 1 July.
Investment as well as the export of key equipment and technology for Iran's petrochemical sector is also banned.
BBC Europe Editor Gavin Hewitt says it is one of the toughest steps the EU has ever taken.
EU foreign policy chief Catherine Ashton said the purpose of
the sanctions was "to put pressure on Iran to come back to the
negotiating table".
Earlier, UK Foreign Secretary William Hague said the embargo showed "the resolve of the European Union on this issue".
"It is absolutely right to do this when Iran is continuing to breach United Nations resolutions," he added.
But the Russian foreign ministry said it was a "deeply
mistaken" move that would not encourage Iran to return to the
negotiating table.
"It's apparent that in this case there is open pressure and diktat, aimed at "punishing" Iran," it said in a statement.
BBC Iran correspondent James Reynolds says the decision may damage the Iranian economy - but in itself it won't destroy it.
Iran sells most of its oil to countries in Asia. The EU and
the United States are now working to persuade Asian countries to reduce
their purchases from Iran as well.
Iran has already threatened to retaliate by blocking the
Strait of Hormuz at the entrance to the Gulf, through which 20% of the
world's oil exports pass.
The US has said it will keep the trade route open, raising the possibility of a confrontation.
Late last year Iran conducted 10 days of military exercises near the Strait of Hormuz, test-firing several missiles.
Oil prices have risen already because of the increasing tension and the expected impact of an EU ban on oil supplies to Europe.
