US - Russia will not station intermediate-range weapons in Europe or other regions until similar U.S. weapons appear in those regions,” he said.

The Russian leader said that Moscow remains open to talks with Washington, but added that it would be up to the U.S. to take the first step.

“Let’s wait until our partners are mature enough to conduct an equal and substantive dialogue on those issues,” he said.

At the same time, Putin told his ministers that he would like to review the progress on building other prospective weapons that don’t fall under the INF treaty, including the intercontinental Avangard hypersonic glide vehicle and the Poseidon underwater nuclear-powered drone.

He noted Shoigu’s report that a key stage in testing of the Poseidon was completed several days ago. The drone is designed to carry a heavy nuclear weapon that could cause a devastating tsunami wave.

The Russian leader last year unveiled an array of new nuclear weapons, including the Avangard and the Poseidon, saying that they can’t be intercepted.

Putin also noted during Saturday’s meeting that he would like the military to prepare a response to the possible deployment of weapons in space.

The Pentagon’s new strategy unveiled last month calls for a new array of space-based sensors and other high-tech systems to more quickly detect and shoot down incoming missiles.

Putin instructed the military to make sure the research and development works on new weapons don’t swell military spending. He said the military must reconfigure the existing defense budget to find money for the new weapons.

“We must not and will not be drawn into a costly arms race,” he said.
