Ferrero-Waldner told journalists after meeting Lavrov that "the door is still open" for a diplomatic solution.
Lavrov declined to comment on what Russia's position would be if the issue of imposing sanctions were discussed in the United Nations Security Council.
Meanwhile, Iranian President Mahmud Ahmadinejad reiterated today that his country will not retreat "an inch" over its nuclear program. He said no political pressure would change this attitude.
