There is no unique definition of an international organisation. A broader meaning usually includes international governmental organisations (IGOs) and international nongovernmental organisations (NGOs). The OECD Glossary of Statistical Terms defines International Organisations as “entities established by formal political agreements between their members that have the status of international treaties; their existence is recognised by law in their member countries; they are not treated as resident institutional units of the countries in which they are located”.
International Organisations play a major role in the Security Sector Governance (SSG), Reform (SSR) and therefore Building Integrity (BI). They provide expertise and advice; raise awareness on security topics; finance capacity development trainings, programmes and projects on a multitude of vital issues such as technical skills, security sector governance, oversight, and building integrity. IOs also play a central role in the process of norm and standard–setting, as well as for ensuring accountability and promoting the rule of law. Moreover, they establish a communication channel between governments and societies, as well as between different nations, and other international entities and actors involved in the field of SSG and SSR.
