Russia developing additional missile systems is not helpful if Moscow wants to save the Intermediate-range Nuclear Forces (INF) Treaty, U.S. Department of Defence spokesperson Johnny Michael said.
"Developing additional non-complaint systems is not helpful if they truly wish to save the [INF] Treaty," Sputnik cited Michael as saying.
Earlier, Russian Defence Minister Sergei Shoigu said that a ground-based version of the Kalibr sea-based systems with a long-range cruise missile would be developed in 2019-2020 in response to the U.S. decision to suspend its obligations under the INF Treaty, and a ground-based system with a long-range hypersonic missile should be created as well.
