Historical relations between Sweden and NATO before the membership process was initiated 

  • Sweden signed a Host Nation Support Agreement with NATO in 2016. This Agreement better enables Sweden to efficiently provide and receive military support from NATO in the event of crisis or war. Host Nation Support comprises both civilian and military support, and practical and logistical arrangements. The aim is to enable foreign military forces to operate and carry out assignments on Swedish territory. Effective Host Nation Support also makes it easier for Sweden to act as a host country for international exercises.
  • In 2014, Sweden entered into a tailor-made partnership with NATO with the status of Enhanced Opportunities Partner, together with Finland and other countries. This type of partnership is focused on political dialogue, training and exercises, and sharing information. The partnership deepened Sweden’s cooperation with NATO.
  • In 1998, Sweden appointed its first Ambassador to NATO. In 2008, Sweden's Delegation to NATO Headquarters in Brussels was established, led by the Ambassador. When Sweden became a full member of NATO in March 2024, the delegation became a representation. The staff at the Permanent Representation of Sweden to NATO consists of posted officials from the Ministry for Foreign Affairs, the Ministry of Defence and the Swedish Armed Forces. 
  • Since the 1990s, the Swedish Armed Forces have enhanced their capability to cooperate with NATO. The aim of this close cooperation with NATO is to improve the ability of Sweden and NATO to act jointly in a crisis situation, ultimately, war. Through participation in NATO-led operations in Bosnia and Herzegovina, Kosovo, Afghanistan, Libya and Iraq, the Swedish Armed Forces has also adapted to NATO’s military standards and developed interoperability. Sweden has taken part in NATO training and exercises within the framework of partnership with NATO. Sweden has also hosted NATO-led training and exercises, and cooperates with NATO on standardisation and capability development. Since 2013, Sweden has participated in NATO’s most advanced exercises, where NATO Allies train collective defence.
  • In 1994, Sweden joined the Partnership for Peace (PfP). The purpose of the PfP is to build trust and facilitate cooperation between NATO and individual non-member countries in the Euro-Atlantic area. In 1997, Sweden also became a member of the Euro-Atlantic Partnership Council, which is a forum for political dialogue between all NATO members and partner countries in the Euro-Atlantic area. The political dialogue in the Euro-Atlantic Partnership complements the more practical cooperation between NATO and partner countries in the PfP.
