NATO, Russia have now both suspended participation in treaty on troop deployments
Treaty of Conventional Armed Forces aims to prevent rivals from stationing troops at mutual borders
NATO on Tuesday announced the formal suspension of a key Cold War-era security treaty in response to Russia's pullout from the deal just hours earlier. The alliance also said members who signed the treaty are now freezing their participation in the pact.
Most of NATO's 31 allies have signed the Treaty of Conventional Armed Forces in Europe, which was aimed at preventing Cold War rivals from massing forces at or near mutual borders. It was signed in November 1990, but not fully ratified until two years later.
NATO said the most recent action was required because "a situation whereby Allied State Parties abide by the Treaty, while Russia does not, would be unsustainable."
Earlier in the day, Moscow said it had finalized its withdrawal from the treaty, also known as CFE. The long-expected move came after both houses of the Russian parliament approved a bill proposed by President Vladimir Putin denouncing the CFE. Putin signed that bill into force in May this year.
The treaty was one of several major Cold War-era treaties involving Russia and the United States that have ceased to be in force in recent years. Russia suspended its participation in 2007, and in 2015 announced its intention to completely withdraw from the agreement.
In February 2022, Russia invaded Ukraine, sending hundreds of thousands of Russian troops into the neighbouring country, which also shares a border with NATO members Poland, Slovakia, Romania and Hungary.
Russia blames U.S.
Russia's Foreign Ministry said the process of the formal withdrawal from the treaty has been completed, without elaborating what that entailed. It blamed the U.S. and its allies for the withdrawal and the West's allegedly "destructive position" on the treaty.
"We left the door open for a dialogue on ways to restore the viability of conventional arms control in Europe," it said. "However, our opponents did not take advantage of this opportunity."

The statement further said that "even the formal preservation" of the treaty has become "unacceptable from the point of view of Russia's fundamental security interests," citing developments in Ukraine and NATO's recent expansion.
Putin last week blamed the Americans when he revoked the ratification of the Comprehensive Nuclear-Test-Ban Treaty.
In Brussels, NATO said its allies who had signed on "intend to suspend the operation of the CFE Treaty for as long as necessary, in accordance with their rights under international law." The alliance underlined that its members remain committed to wanting "to reduce military risk, and prevent misperceptions and conflicts."
NATO said that its members will continue to "consult on and assess the implications of the current security environment and its impact on the security" of the alliance.
