MOSCOW. June 5 (Interfax) - Lack of agreements between the P5+1 mediators and Iran put in writing by June 20 is fraught with serious issues in the negotiating process, Russian Deputy Foreign Minister Sergei Ryabkov said.
"If we leave on June 20 (…) still with no results stipulated in writing, then it can be said that real and serious issues will begin," Ryabkov said in an interview with Interfax.
Next round of talks between the P5+1 and Iran will be held in Vienna in June 16-20.
