The UN's top powers have warned Iran it has 30 days to resume talks over its nuclear programme or face isolation. Here is what the various parties have said.
US Secretary of State Condoleezza Rice
"I think this does send a very strong signal to Iran that the international community is united and expects Iran to adhere to the just demands... that its nuclear activities be demonstrably for civilian purposes and that there are ways that Iran can have a civil nuclear programme, that's not an issue.
UK Foreign Secretary Jack Straw
"The onus is on Iran to show the international community that its programme is entirely for civil purposes and for no other. We have shown very great patience with Iran. They, in turn, have miscalculated. They thought the international community would be divided on this issue but truthfully it has become more and more united."
Chinese foreign ministry spokesman Qin Gang
"We think under the present circumstances there is still room to resolve the Iran nuclear issue through diplomatic negotiations. The international community shouldn't give up their efforts. We hope relevant parties should remain restrained and patient, and create a favourable environment for the resolution of the Iran nuclear issue through diplomatic means."
Russian Foreign Minister Sergei Lavrov
"Russia believes that there is no other solution to this problem and if we follow this route it must be with the full cooperation of Iran. Only then will it be possible for Iran to make peaceful use of nuclear technology."
German Foreign Minister Frank-Walter Steinmeier
"Iran has to take a choice between isolation brought about by actions of its own and the continuation of enrichment activities on its own soil in violation of the commitments to the international community, or a return to the negotiating table. We all very much hope that Iran will seize the opportunity offered to it to resume the negotiations."
French Foreign Minister Philippe Douste-Blazy
"What are we demanding? What's the path we should follow? It's the complete suspension of nuclear activities in Iran. Nuclear activities for a civilian purpose, of course, are something that we are proposing, we are in agreement - everyone round the table said so. And we also demand that there is a complete suspension of sensitive activities, including research and development."
Iranian Foreign Minister Manouchehr Mottaki
"Those who have used nuclear weapons in the past and by doing so, have created the most heinous of tragedies in the history of the human race, I would say today are claiming to be the champions of disarmament. Iran's drive to have access to peaceful nuclear technology is what is rightfully ours."
