European Union foreign policy chief Javier Solana says negotiators are "really making progress" on resolving the standoff over Iran's nuclear program.
Solana said in Brussels Friday that never before has there been this "level of engagement" in talks with Iranian officials.
Earlier Friday, France confirmed that Iran's chief nuclear negotiator, Ali Larijani, said his country is ready to discuss suspending its uranium enrichment program.
Iran ignored an August 31 U.N. Security Council deadline to suspend uranium enrichment.
In Washington, President Bush said he wants to make sure Iran does not stall, and repeated the demand that Tehran suspend its enrichment activities. Mr. Bush said he will not meet with Iranian President Mahmoud Ahmadinejad when both leaders are in New York next week for the U.N. General Assembly.
Mr. Bush said the United States is prepared to hold talks with Iran - once it verifiably suspends enrichment.
The United States and many of its European allies believe Iran is enriching uranium as part of a program to build nuclear weapons - a charge Iran denies.
