"We have to deal with the mutual accusations first and then talk about renewal [of START III treaty]," Shamanov said.
The lawmaker added that Russia was ready for constructive negotiations and repeatedly invited the US side to engage in the talks.
Earlier this week the Russian Foreign Ministry said that Moscow and Washington were not holding talks on the new START treaty, and it was premature to talk about further steps in this area.
The first START (Strategic Arms Reduction Treaty), a bilateral agreement between the United States and the Soviet Union on strategic offensive reductions was signed on July 31, 1991, with a duration of 15 years and an extension option and obliged the signatories to limit the number of warheads and delivery vehicles. The agreement remained in force until it expired in December 2009.
On February 5, the Russian Foreign Ministry claimed the United States had reconfigured a certain number of submarine ballistic missile launchers and heavy bombers and that Russia "could not confirm that these strategic arms have been rendered incapable of employing SLBMs or nuclear armaments for heavy bombers" as specified in the treaty.
