Iran and the P5+1 (five permanent members of the U.N. Security Council and Germany) have so far failed to resolve their disagreements over key issues that need to be cleared before the final agreement on the Iranian nuclear programme can be signed, Russian Deputy Foreign Minister Sergei Ryabkov said on Wednesday.
Ryabkov, who is leading the Russian delegation at the current round of talks, said earlier that the most challenging issues were the Arak reactor, uranium enrichment, verification, and the closure of the so-called military dimensions of the Iranian nuclear programme.
He added that there was no reason yet to hold a ministerial meeting of between Iran and the P5+1.
“A ministerial meeting will depend on whether at least some of the solutions to the main issues can be stated. There is none so far, unfortunately,” he said.
