U.S. officials say differences remain in talks with India on a civilian nuclear cooperation agreement, but there is hope a final deal can be reached before President Bush visits New Delhi next month.

The U.S. Embassy released a statement Saturday expressing hope for an agreement after Washington's negotiator, Nicholas Burns, left New Delhi following three days of talks.

Washington has offered to provide India with civilian nuclear technology, but wants assurances that the Indian government will not use the technology for military purposes.

President Bush has said he wants to return from India with a final nuclear cooperation pact so he can begin work on getting approval from Congress.  Mr. Bush's national security advisor, Stephen Hadley, said Friday that if no deal is reached before the visit, negotiations will continue after the president's trip.
