Russia and the West are divided on how well the U.N. atomic agency is reporting on whether Tehran is meeting its commitments. Western nations want more details while Moscow opposes their push.
Because all six want to avoid conflicts that could complicate Iranian compliance of a deal that was years in the making, their differences are mostly playing out behind the scenes.
Moscow's chief delegate to the U.N.'s International Atomic Energy Agency, which is monitoring the deal, acknowledges there is a dispute that could affect the amount of information made public about Iran's nuclear program in the future.
The IAEA board plans to discuss the agency's latest Iran report Tuesday. Ahead of that, Vladimir Voronkov says Moscow is happy with the document but some countries would like “more details.”
