of energy security, promotion of strategic communication, reinforcing cyber security, fight against hybrid threats) and support for the EU Eastern Partnership. In 2017, the coordinating country was Norway. The priorities were set in regional issues (regional security, hybrid and resilience issues, cybersecurity, open and free media, strategic communication, energy security and energy markets, EU Eastern Partnership, attention to the Estonian Presidency of the Council of the EU, economic development, competitiveness and innovation, synergies among Nordic 5, NB6 and Nordic Council of Ministers). The other set of priorities was based in broader strategic issues (transatlantic relations (United States, NATO, Euro-Atlantic bonds), the future of the European Union, Brexit, migration, the Bratislava process), Russia, UN issues (including the Security Council) and terrorism. In 2020, Estonia coordinated both the NB8 as well as the Baltic Council of Ministers. Its priorities in both settings were regional security, including the Eastern Partnership, transatlantic relations; cyber cooperation; connectivity, including regional energy and transport projects and digital cooperation; climate change and environmental issues; and cultural and health cooperation. NB8 format On the political level, co-operation in the NB8 format is conducted primarily in the form of annual meetings of the Prime Ministers and Foreign Ministers. The Foreign Ministers' meetings have taken place since 1993. In addition to the foreign ministers and prime ministers, other ministers and ministry officials also meet on a regular basis. In the realm of foreign policy, there are many meetings held in addition to the annual meeting of the foreign ministers. The secretaries general, political directors, and experts in various fields from the foreign ministries also get together regularly, and there are frequent meetings of diplomats in foreign representations within the NB8 format. During the recent years the Baltic and Nordic countries have developed a cohesive network of cooperation activities in political, military, economic, environmental, cultural and other aspects. After double the EU and NATO enlargement in 2004 the cooperation is becoming closer thereby activating the vast potential for development in the Baltic Sea region. Several examples of such evolved cooperation is the work of NB8 Task Force against Trafficking in Human Beings and the creation of the common Nordic – Baltic education and research area. On 17 August 2010, the financial supervisory authorities, central banks, finance ministries and other relevant ministries of Denmark, Estonia, Finland, Iceland, Latvia, Lithuania, Norway and Sweden signed a cross-border agreement on financial stability.
