TEHRAN, Dec. 27 (Xinhua) -- Iran and the P5+1 group will resume their expert-level nuclear talks next week, Iran's nuclear negotiator said on Friday.
The meeting aimed at developing mechanisms to implement an earlier deal between them will be resumed in Geneva on Dec. 30, Abbas Araqchi was quoted as saying by official IRNA news agency.
The technical and expert-level negotiations between Iran and the P5+1 group -- the United States, Britain, France, Russia, China plus Germany -- were halted on Sunday for Christmas after four days of talks.
On Sunday, Iranian Foreign Minister Mohammad-Javad Zarif said the talks were advancing slowly since they "are not easy and the details should be discussed accurately."
On the same day, Araqchi told IRNA that there was "little progress in the talks" and that different interpretations of the interim deal had been the reason for the slow progress.
An interim deal was struck in Geneva on Nov. 24, in which Iran agreed to freeze part of its nuclear program in exchange for limited ease of sanctions which had hurt its economy.
Earlier this month, Iran quit the expert-level meeting in protest of the United States' blacklisting of additional individuals and companies allegedly violated existing Western sanctions against Iran.
