Russia's behavior is tantamount to unilaterally withdrawing from the 1997 cooperation agreement with NATO.
This was stated by German Foreign Minister Annalena Baerbock, according to Reuters.
“The russian government has made it clear that the russia-NATO Founding Act is no longer worth anything. So now we have to recognize that this basic act was also unilaterally broken by russia, not NATO”, Baerbock said.
The 1997 agreement was designed to build trust and limit the military presence of both sides in Eastern Europe. In 2014, after russia's capture of Ukraine's Crimea, NATO suspended practical cooperation with the aggressor country. Instead, russia suspended its mission to NATO and closed the alliance's Moscow office in October 2021 in response to the expulsion of russian diplomats.
As stated earlier, NATO countries have agreed to continue supporting Ukraine to help it “displace russia”.
