Iran and six world powers agreed to start implementing their interim deal on Iran's nuclear program in late January, an Iranian negotiator was quoted as saying by Press TV on Tuesday. "Based on the conclusions (reached in) the talks held with the P5+1 expert delegations, the implementation of the Geneva accord will start in the third 10-day (period) of January," Hamid Baeidinejad, an expert-level Iranian negotiator said. Iran and the world powers concluded two days of expert-level talks in Geneva on Tuesday, following the signing of the landmark deal in the same Swiss city last month. "The two sides managed to reach an understanding on the implementation of the agreement and now, their views and interpretations (of the Geneva agreement) are the same," said Baeidinejad, who is also director general for political and international affairs at Iran's Foreign Ministry. On Tuesday, senior Iranian nuclear negotiator Abbas Araqchi said the expert-level talks between Iran and the P5+1 group -- Russia, China, France, Britain, the United States and Germany -- advanced "with relatively good progress," according to the TV. Araqchi said that the Iranian negotiating team will submit their reports to "political deputies and directors, since certain issues remained to be resolved at the political level." The 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.
