TEHRAN - Iran's top nuclear negotiator has said that the ground is prepared for a final deal with world powers over Tehran's nuclear issue, Press TV reported on Thursday.

"If the Western side is determined to reach a mutually satisfactory deal with goodwill, the conditions are prepared more than any other time," Abbas Araqchi was quoted as saying here at a meeting Wednesday with Italian Deputy Foreign Minister Lapo Pistelli.

Pistelli, for his part, said the nuclear negotiations proved dialogue could serve as a proper model for cooperation between the two sides on other regional and international issues.

After seven days of intensive talks which failed to meet the initial Nov. 24 deadline for a comprehensive deal over Tehran's controversial nuclear program, foreign ministers from the Islamic republic and the P5+1 group (China, the United States, France, Britain, Russia plus Germany) agreed to extend the deadline for another seven months.

Under the agreement, an interim deal reached on Nov. 24, 2013, will also be extended to June 30, 2015, with a fresh round of talks resuming in December.
