"We already told the US on the sidelines of the bilateral advisory commission, established by the new Strategic Offensive Arms Reduction Treaty (START), that we had presented our new [missile] systems, including hypersonic ones. We proceed from the fact that Avangard and Sarmat systems are covered by the treaty. We are ready to include these systems in the New START Treaty, of course, when it will be extended. Moreover, we have already shown Avangard [system] to the US and, at a certain stage, we will be ready to do the same with Sarmat [system]," Lavrov said.
The minister also recalled that other missile systems were not envisaged by the treaty, therefore, Moscow was ready to discuss the matter in separate talks.
The New START is a nuclear arms reduction treaty that was signed between the United States and Russia in 2010 and came into effect the following year, being expected to last until 2021.
It is the last remaining arms control treaty in force between Russia and the US, which limits the number of deployed strategic nuclear warheads to 1,550.
