President Vladimir Putin a day later said Moscow would also abandon the accord, which restricts the deployment of missiles with a range of 500 kilometers (311 miles) to 5,500 kilometers.
"They are part of a broader picture where we have seen Russian Federation investing heavily in modern military capabilities over a long time, including new nuclear capabilities", he said. "We urge Russian Federation to take this opportunity", he stated.
The warning came after President Donald Trump said on February 1 he would pull out of the landmark 1987 nuclear disarmament treaty, called the Intermediate-Range Nuclear Forces Treaty, citing years of Russian violations. North Atlantic Treaty Organisation allies made a decision to deploy US cruise and Pershing 2 ballistic missiles in Europe in 1983 as negotiations with Moscow faltered over its stationing of SS-20 missiles in Eastern Europe.
Speaking at NATO headquarters, where defence ministers are discussing what to do if the imperiled treaty is abandoned, Stoltenberg said: "This is very serious". NATO is planning defensive measures in a world without the Intermediate-Range Nuclear Forces (INF) Treaty but does not intend to deploy new missiles in Europe, NATO Secretary General Jens Stoltenberg said at a press conference on Tuesday ahead of a meeting between the alliance's defense chiefs.
Mr Putin immediately announced Russian Federation will start work on creating new missiles, including hypersonic ones, and told his ministers not to initiate disarmament talks with Washington.
While Washington and Moscow are at odds over the INF, the treaty does nothing to constrain China, whose fast-growing military depends on medium-range missiles as a key aspect of its defense strategy.
"They are deploying more and more of the new nuclear capable missiles in Europe". Turkey finalized plans to buy the Russian systems, called the S-400, last year, with first delivery scheduled for October 2019.
"Our allies want to know what the future will be, and the future will be that we will start the development of a defensive mechanism and we will keep our allies informed all along the way".
Secretary General Jens Stoltenberg said after the meeting that Russia's SSC-8 missile system is a significant risk to the security of the Alliance.
