EU relation with the International Organisations in Vienna
The EU's commitment to effective multilateralism, with the United Nations at its core, is a central element of its external action. This commitment is rooted in the conviction that to respond successfully to global crises, challenges and threats, the international community needs an efficient multilateral system, founded on universal rights and values
All EU Member States are participating States of the Organisation for Security and Co-operation in Europe (OSCE). Altogether, the OSCE has 57 participating States from Europe, North America, and Central Asia and spans a geographical area from Vancouver to Vladivostok. All 57 participating States enjoy equal status and decisions are taken by consensus on a politically, but not legally binding basis.
Diplomatic efforts by the E3/EU+3 (China, France, Germany, the Russian Federation, the United Kingdom, the United States, the High Representative of the European Union for Foreign Affairs and Security Policy), and Iran to reach a comprehensive and long-term solution to the Iranian nuclear issue, resulted in the conclusion of the Joint Comprehensive Plan of Action (JCPOA) (UN resolution 2231 - 2015) on 14 July 2015.
