"Russia has very serious concerns about how the US is fulfilling its obligations [under the treaty]. Today, instead of the actual disarmament process, the United States is more concerned about maintaining its breakout potential. This means that as soon as the New START Treaty expires, they could return it all to the arsenal and gain certain military superiority," the source said.
The source also noted that Russia was in favour of extending the treaty but stressed that the existing issued should be solved first.
"We believe it is necessary to first resolve all the differences and discrepancies that we have and extend the treaty with the understanding that it is being fully implemented," the source pointed out.
In addition, it stated citing the ongoing Russia-US inter-ministerial discussions, that "the United States is saying unequivocally that the issue [of extending the treaty] is under consideration, and that they are examining a wide variety of options."
"They believe they still have time. So far, there has been no clear signal that [the United States] wants to extend the treaty," the source stressed.
This comes after Russian Deputy Foreign Minister Sergei Ryabkov said at the Munich Security Conference on 16 February that there was a growing risk that the US administration was dragging out time by refusing to engage in a genuine dialogue on the New START so that Moscow and Washington would fail to extend the accord before its expiration.
The aggregate limits of the treaty restrict the United States and Russia to 1,550 deployed strategic warheads each. The pact also includes an aggregate limit of 800 deployed and non-deployed intercontinental ballistic missile (ICBM) launchers, Submarine-launched ballistic missile (SLBM) launchers, and heavy bombers equipped for nuclear armaments. Within that limit, the number of deployed ICBMs, SLBMs, and heavy bombers cannot exceed 700.
