VIENNA (Sputnik) — There is no clear understanding with regard to a detailed approach toward ensuring transparency when it comes to Iranian military matters, Ryabkov said.
"This is one of the main stumbling points within the P5+1. We have not reached understanding on this issue," Ryabkov told reporters.
Lifting of an arms embargo has been one of the stumbling blocks in talks between Iran and the P5+1 group. The UN Security Council issued a resolution in March 2007 imposing an arms embargo on Tehran amid accusations that the country was trying to create nuclear weapons under the guise of a civilian nuclear program.
According to Ryabkov, the P5+1 group and Tehran will resume consultations on the comprehensive nuclear agreement at the level of political directors in Vienna on June 24-25, while a date for the ministerial meeting is yet to be confirmed.
