This was stated in an interview with TASS by Vladimir Yermakov, Director of the Department for Nonproliferation and Arms Control of the Russian Foreign Ministry.
According to him, Russia will assess the speed and range of American-made missile systems capable of appearing in the Asia-Pacific region.
"In particular, Russia's readiness to continue to adhere to a unilateral moratorium on the deployment of ground-based intermediate-range and shorter-range missiles in certain regions will fundamentally depend on the specific parameters of their range," Yermakov said.
He argues that the "destabilizing military programs of the United States and its allies" make the moratorium "increasingly fragile."
On February 21, Russian President Vladimir Putin announced that Moscow was suspending its participation in the New START Treaty. He noted that a situation in which the US military is at Russian nuclear facilities, while the United States is fomenting a further escalation of the Ukrainian conflict, is simply impossible.
After that, the US State Department said that Washington considers it "legally incorrect" for Russia to suspend its participation in the New START Treaty.
Deputy State Department spokesman Vedant Patel noted that the United States continues to work to preserve the Strategic Arms Reduction Treaty (START).
