The US has begun its withdrawal from the INF treaty with Russia, prompting Moscow to also suspend its participation in the 1987 arms control pact. President Putin said Russia would start work on building new missiles.
The withdrawal "will be completed in 6 months unless Russia comes back into compliance by destroying all of its violating missiles, launchers, and associated equipment," it said in a statement.
The US would develop "military response options" and work with its NATO allies "to deny Russia any military advantage from its unlawful conduct," it added, without elaborating.
Trump suggests new treaty
President Vladimir Putin announced Saturday that Russia too would be suspending its participation in the treaty.
"Our American partners have announced they are suspending their participation in the deal, and we are also suspending our participation," Putin said.
Speaking at a televised meeting with foreign and defense ministers, Putin said Russia would begin creating new intermediate-range missiles but would not deploy them unless the US did so first. The Russian president also told ministers not to seek disarmament negotiations with Washington.
"We will wait until our partners have matured enough to conduct an equal, meaningful dialogue with us on this important topic," he said.
Earlier, US President Donald Trump told reporters that he was interested in holding talks to create a new arms control treaty.
"I hope that we're able to get everybody in a big and beautiful room and do a new treaty that would be much better," he said, without elaborating.
