Moscow sees the US plan as posing a threat to its security, while Washington says it is not targeted at Russia.
Russian Deputy Foreign Minister Sergei Kislyak was quoted by Itar-Tass as saying earlier that Moscow does not try to scuttle arms control efforts.
"We're not aiming to cause any damage to arms control, but wish to give an impulse to the restoration of the CFE's viability," Kislyak told lawmakers at the State Duma.
"It was a decision of necessity to impose a moratorium on the operation of the treaty, a clear signal to the partners that all the parties -- not only Russia -- must meet their commitments," he said.
