Implementation of the November 24 interim deal to limit the Iranian nuclear program in exchange for eased sanctions on the Islamic Republic will commence on January 20, Hamid Baeedinejad, the head of the Iranian negotiating team, said Wednesday.

“The two sides managed to reach an understanding on the implementation of the agreement, and now their views and interpretations are the same,” Baeedinejad was quoted by the semi-official Fars news agency as saying.

The announcement came a day after Western and Iranian officials said they were nearing an understanding on the technical details of implementing the landmark interim nuclear accord.

The deal puts curbs on Iran’s uranium enrichment program in return for an easing of some international sanctions on Tehran for six months while a permanent deal is negotiated.

The United States and its allies believe Iran’s nuclear program is aimed at producing a nuclear weapon, a claim that Tehran denies, saying it is intended only for peaceful purposes.

Over the past month, experts from Iran and the P5+1 countries — the US, Britain, France, Russia, China and Germany — have held several rounds of talks in Geneva to work out the details of the agreement.
