“In a legal sense, the Founding Act continues to exist, we have not initiated the procedure for terminating this agreement,” he said.

In March, Polish President Andrzej Duda announced that the Russia-NATO Founding Act on Mutual Relations, Cooperation and Security “no longer exists” and binds no one.

Later, in early May, the head of the military committee of the alliance, Robert Bauer, said that the provisions of the Russia-NATO Founding Act of 1997 did not prevent the expansion of NATO's military presence in Eastern Europe.

Deputy Chairman of the Security Council of Russia Dmitry Medvedev reacted to the statements of the NATO members that "they no longer consider themselves bound" by this document.

Ambassador-at-Large of the Russian Foreign Ministry Grigory Mashkov said that it would not be possible to restore the system of European security destroyed by the West on the same terms.
