Following the Cold War's waning tensions, European states sought structured mechanisms to reduce military mistrust and prevent conflict. The need for transparency regarding armed forces and military activities prompted multilateral negotiations under the Conference on Security and Co-operation in Europe framework.
In 1990, participating European states adopted the Vienna Document, a set of confidence- and security-building measures governing military activities. The agreement required notification and observation of military exercises and exchanges of military data, and has been updated in 1992, 1994, 1999, and 2011 to reflect changing security conditions.
The Vienna Document 2011, adopted by 57 OSCE states including Russia and Central Asian nations, remains the primary multilateral instrument for military transparency in Europe. It established a defined zone of application covering all of Europe and adjacent areas, contributing to ongoing efforts to reduce the risk of armed conflict through openness.
Political Outcome
Adoption of binding confidence- and security-building measures governing military transparency among European states, updated four times through 2011.
