MOSCOW, Dec. 18 (Xinhua) -- Russia will have to take additional measures to boost its security if the United States withdraws from the Intermediate-range Nuclear Forces (INF) Treaty, Russian President Vladimir Putin said Tuesday.

A U.S. withdrawal from the INF Treaty may ruin the entire arms control system, said the Russian president.

"Such a step will have the most negative consequences, and will noticeably weaken regional and global security," Putin said speaking at an extended meeting of the Russian Defense Ministry board.

"In fact, in the long term, the talk is about the degradation and even collapse of the entire arms control architecture and the non-proliferation of weapons of mass destruction," he added.

For a long time, the United States has been using unsubstantiated accusations that Russia had violated its obligations under the treaty as a pretext to withdraw from it unilaterally, thus violating the treaty itself, Putin said.

He agreed that the INF Treaty did not involve other countries which have medium and shorter range missiles.

"But what prevents us from starting negotiations on their accession to the current agreement, or starting to discuss the parameters of a new treaty?" Putin said.

The treaty, in modern conditions, plays the role of a stabilizing factor, which allows maintaining a certain level of predictability and restraint in the military sphere, he said.

He recalled that the INF Treaty signed in 1987 involved the elimination of medium-range and shorter-range (500-5,000 km) ground-based missiles. At the time, the USSR had no other missiles, while the United States had sea-based and air-launched missiles.

Russia, since the signing of the treaty, has developed sea-based and air-launched missiles, which was the cause for Washington's concern, Putin said.

According to Putin, it will not be difficult for Russia, if necessary, to create appropriate land-based systems as a response to the U.S. withdrawal from the INF.

However, Russia is always open to any proposals and initiatives that lead to the strengthening of universal security including the prevention of a new arms race in the interests not only of Russia, but of the United States and the whole world, Putin said.
