WASHINGTON (AP) - Iran says it is ready to resume talks with world powers over its disputed nuclear program.

The top Iranian nuclear negotiator says Tehran is committed to a dialogue on its uranium enrichment program that welcomes its right to peaceful nuclear energy production.

But the letter from Saeed Jalili in response to a letter from EU foreign policy chief Catherine Ashton offers no new concessions. It is likely to be viewed skeptically in Western capitals, wary of delaying tactics from Tehran while they implement tough sanctions on the Iranian economy.

The one-page, four-paragraph letter was dated Tuesday. An English translation was obtained Wednesday by The Associated Press.

Iran claimed Wednesday it has achieved two major advances in its program to master production of nuclear fuel.
