MOSCOW. Nov 8 (Interfax) - Other nuclear powers should join the nuclear arms reduction dialogue of Russia and the United States, Russian Deputy Foreign Minister Sergei Ryabkov said at the international conference Nuclear Weapons and International Security in the 21st Century on Thursday.
"The next phase of the negotiations must be multilateral," he said.
"I think it is impossible to continue arms control negotiations in the bilateral, U.S.-Russian, format," the diplomat said.
