Iran will ask for �clarification� from US negotiators with regard to �contradictory expressions� about the removal of sanctions imposed on Tehran over its nuclear program, says an Iranian high-ranking official.

Less than 24 hours after Iran and the P5+1 reached a mutual understanding over Tehran's nuclear program earlier this month, the US published its own fact sheet detailing the parameters for the Joint Comprehensive Plan of Action (JCPOA). The sheet, however, had differences with the original joint statement.

Although Iran has reiterated that all sanctions have to be lifted simultaneously as soon as the final deal comes into force, the US edition indicates that the architecture of nuclear-related sanctions will be retained for much of the duration of the deal.

�Certainly, we would ask for some clarification and explanation by the US delegation on such developments,� Iranian Foreign Ministry's Director General for Political Affairs Hamid Baeidinejad told Press TV on Wednesday.

Against the backdrop of a row between the US dominant parties, President Barack Obama gave in to pressure imposed by the Republican-weighted Congress over the review of any deal with Tehran in mid-April.

�No disagreement� on nuclear R&D

Baeidinejad further said that there was �no disagreement� over Iran�s nuclear research and development.

�There is an agreement on the modality and the detailed aspects of the R&D,� he said, adding, �The thing that should be done at this stage is how we bring these details into the text... What we are aiming at this stage is how we can bring the detailed aspects of our agreement on enrichment, on sanctions, and on other things into a coherent text."
Iranian Foreign Minister Mohammad Javad Zarif wrote on his Facebook page on Tuesday that his colleagues were to start the process of drafting the agreement between Iran and the P5+1 -- the United States, Russia, China, France, Britain, and Germany -- on the following day.

Iran and the P5+1 group reached a landmark understanding over Tehran�s nuclear program in Switzerland on April 2. The two sides will now work to draft a final accord by the end of June.
