Nordic-Baltic Eight (NB8) is a regional co-operation format that includes Denmark, Estonia, Finland, Iceland, Latvia, Lithuania, Norway, and Sweden. Under NB8, regular meetings are held of the Baltic and Nordic countries' Prime Ministers, Speakers of Parliaments, Foreign Ministers, branch ministers, Secretaries of State and political directors of Foreign Ministries, as well as expert consultations where regional issues and current international topics are reviewed. History Historically, the countries of the region have been interlinked and interacted for centuries, with mutual trade being the decisive factor facilitating this interaction. The most profound bond, however was created during the 1990s. The Nordic Council first contacted Baltic parliamentarians in around 1989. Official co-operation began in November 1991, when the Nordic Council attended the inaugural meeting of the Baltic Assembly in Tallinn. A formal co-operation agreement between the Nordic Council and the Baltic Assembly was signed in 1992. The Nordic countries were amongst the strongest supporters of the Baltic countries' independence and later they were the first to open their borders, introducing visa-free regimes with the Baltic countries. When Baltic countries regained their independence and during their integration into the European and transatlantic structures, they were strongly supported by their Nordic neighbors. The Nordic-Baltic co-operation took place in various levels: networking and cooperation were established among politicians, civil servants and civil societies. The Nordic countries actively assisted the Baltic countries in their preparations for integration into the European Union and NATO. Named as 5+3 in the beginning of cooperation (five Nordic countries plus three Baltic States), the format changed its name and scope of cooperation. During the meeting of the Ministers of Foreign Affairs of the Baltic States and Nordic Countries on 30 August 2000 in Middelfart (Denmark), the Ministers decided that the meetings of the Ministers of the Baltic States and Nordic Countries will be called NB8. Nordic–Baltic countries today The Nordic–Baltic community is one of the three main communities in Northern Europe: these are Nordic, Baltic and Baltic Sea Region.

Furthermore, the region features relatively low levels of corruption; with the Nordic countries being some of the least corrupt countries in the world. Also, the countries of the region place well in various international freedom rankings, with several of the states at the absolute top.
