The United States and five partner countries have accepted Iran's new offer to hold talks, even though Iran insists it will not negotiate over its disputed nuclear program, the State Department said Friday.

Department spokesman P.J. Crowley told reporters that although Iran's proposal for international talks -- presented to the six powers on Wednesday -- was disappointing for sidestepping the nuclear issue, it represented a chance to begin a direct dialogue.

"We are seeking a meeting now based on the Iranian paper to see what Iran is prepared to do," Crowley said. "And then, as the president has said, you know, if Iran responds to our interest in a meeting, we'll see when that can occur. We hope that will occur as soon as possible."

In its proposal, Iran ignored a demand by the six world powers -- the U.S., Russia, China, France, Britain and Germany -- for a freeze of its uranium enrichment, which is suspected of leading to production of a nuclear weapon. Iran insists that its nuclear work is strictly for peaceful non-military purposes.

Iran pronounced itself ready to "embark on comprehensive, all-encompassing and constructive negotiations."

On Monday, Iranian President Mahmoud Ahmadinejad said his country will neither halt uranium enrichment nor negotiate over its nuclear rights but is ready to sit and talk with world powers over "global challenges."
