The development of the agreements reached was consolidated at the meetings of the participating states:
- 1977-1978 - Belgrade,
- 1980-1983 - Madrid,
- 1984 - Stockholm,
- 1986 - Vienna.
- November 19-21, 1990 - Paris meeting of heads of state and government of the CSCE participating states. The Charter of Paris for a New Europe (which proclaimed the end of the Cold War) was signed here, the Treaty on Conventional Armed Forces in Europe (CFE) was concluded, a joint declaration of 22 states (NATO and Warsaw Pact members) was adopted, and the current three-stage mechanism of political consultations was created: meetings at the highest level, Council of Foreign Ministers (CMFA), Committee of Senior Officials.
- September 10 - October 4, 1991 - Moscow Third Final Meeting of the Conference on the Human Dimension of the CSCE (the first was held in 1989 in Paris, the second - in 1990 in Copenhagen). A document was adopted, which for the first time states that issues related to human rights, fundamental freedoms, democracy and the rule of law are of an international nature, and obligations in the field of the human dimension are not exclusively the internal affairs of the CSCE member states.
- 1992 - Helsinki Summit. The document “The Challenge of the Times of Change” was adopted, which marked the beginning of the transformation of the CSCE from a forum of predominantly political dialogue between the participating states into a trans-regional organization aimed at maintaining military-political stability and developing cooperation “from Vancouver to Vladivostok”. The CSCE received wide powers and opportunities to take practical measures to prevent and resolve local and regional conflicts.
- 1992 - Stockholm meeting of the Foreign Ministry Council. The post of Secretary General of the CSCE was established.
Subsequent OSCE meetings were uneventful
