In 1990,
Russia and the
Western nations signed the
Treaty on Conventional Armed Forces in Europe and in 1991 the
Energy Charter Treaty, establishing a multilateral framework for cross-border cooperation in the
energy industry, principally the
fossil fuel industry; Russia postponed ratification of the latter treaty, linking it to the adoption of the Energy Charter Treaty Transit Protocol. In 1994, the
Budapest Memorandum was signed where Russia, the
United Kingdom, and the
United States made security assurances to
Belarus,
Kazakhstan, and
Ukraine, in return for handing over by these three countries of their post-Soviet nuclear arsenal. In 1997, NATO and Russia signed the
Russia–NATO Founding Act, which stated that each country had a sovereign right to seek alliances. NATO ended up
expanding to sixteen Eastern countries (apart from the
GDR in 1990):
Czech Republic,
Hungary, and
Poland in 1999;
Bulgaria,
Estonia,
Latvia,
Lithuania,
Romania,
Slovakia, and
Slovenia in 2004;
Albania and
Croatia in 2009;
Montenegro in 2017;
North Macedonia in 2020;
Finland in 2023; and
Sweden in 2024, five of them on the border with Russia.
Russia–NATO relations started to deteriorate rapidly following the Ukrainian
Orange Revolution in 2004–2005. In December 2006, Russia indicated that the ratification of the Energy Charter Treaty was unlikely due to the provisions requiring third-party access to Russia's pipelines. In 2007 Russia suspended its participation in the Treaty on Conventional Armed Forces in Europe. In 2008, the relations deteriorated further and became almost openly hostile, following the
2008 Kosovo declaration of independence from Russia's ally
Serbia and its partial recognition by the West, to which Russia responded in August 2008 with launching the
Russo-Georgian War. On 20 August 2009, Russia officially informed the depository of the Energy Charter Treaty (the
Government of Portugal) that it did not intend to become a contracting party to the treaty. On 1 April 2014, NATO unanimously decided to suspend all practical co-operation with the Russian Federation in response to the
annexation of Crimea, but the NATO-Russia Council (NRC) was not suspended. In 2015, Russia entirely terminated its participation in the Treaty on Conventional Armed Forces in Europe. On 18 February 2017, Russia's
minister of foreign affairs,
Sergey Lavrov, said he supported the resumption of military cooperation with the NATO alliance. In late March 2017, the Council met in advance of a NATO foreign ministers conference in Brussels, Belgium. After the subsequent
2022 Russian invasion of Ukraine, the Founding Act has been considered by the NATO member states as definitively abrogated in its entirety by Russia, while the latter has been declared at the
2022 NATO Madrid summit "a direct threat" to Euro-Atlantic security. Some commentators, such as
Stephen F. Cohen, as well as
Mikhail Gorbachev in 2008, have advanced in later years the interpretation of a comment allegedly made by US Secretary of State,
James Baker, to the effect that NATO would expand "not one inch eastward" in a unified Germany, as applying instead to Eastern Europe; neither has such a provision been included in the treaty, nor any of the parties has proposed or demanded its inclusion, and neither a recording nor written minutes of Baker's comment exist. In 2014, Gorbachev said that the assurance only pertained to East Germany, and that the resulting agreement was upheld by NATO. His main aide in these negotiations,
Eduard Shevardnadze, likewise agreed that NATO never made any such commitment regarding other countries in Eastern Europe, and that "the question never came up" in the talks on German reunification. That is presumably because all of the countries in question were still in the
Warsaw Pact at the time and hosted large Soviet garrisons. Gorbachev and his successor,
Boris Yeltsin, felt that NATO's later acceptance of countries like Poland violated the spirit of the earlier agreements. In December 2017, researchers Tom Blanton and Svetlana Savranskaya argued that declassified documents challenged this narrative. They further said that, Additionally, he stated that, In her 2021 book
Not One Inch: America, Russia, and the Making of the Cold War Stalemate,
Mary Elise Sarotte balanced out these different interpretations, concluding that Russian claims of betrayal are in fact untrue in law but have psychological truth. On 18 February 2022, German magazine
Der Spiegel published an investigation of the
British National Archives in which Joshua Shifrinson (
Boston University) discovered a memo classified as "secret" dated 6 March 1991 (approximately five months after the 2+4 negotiations). The memo is about a meeting of the directors of the US, UK, French and West German foreign ministries in Bonn. According to the memo,
