Germany's Foreign Minister Frank-Walter Steinmeier says there is still time for Iran to agree to talks on its nuclear program and avoid international sanctions.
Steinmeier told a European radio broadcaster (Inforadio) that European Union leaders are set to meet Tuesday to discuss backing sanctions by the U.N. Security Council.
He called on Iran to agree to suspend enrichment activities, saying that currently there is no possibility for successful talks with Iran.
Western nations say Iran must suspend enrichment before a new round of negotiations on its nuclear program. Iran has rejected the suspension as a condition for talks.
U.S. officials say the five permanent members of the Security Council - United States, Britain, Russia, France and China - plus Germany have reached broad agreement on sanctions against Iran.
Western nations accuse Iran of seeking nuclear weapons, which Iran denies.
