Bilateral defence cooperation

Cooperation with strategic Allies such as the United States, the United Kingdom and the countries in the Baltic Sea region is of particular importance to Sweden’s security. The cooperation with Finland is Sweden’s farthest-reaching defence cooperation.

Finland

Sweden and Finland have similar security policy perspectives and cooperate closely on defence. The purpose of this cooperation is to enhance both countries’ defence capabilities, enable joint operations and promote common defence interests to strengthen security in the Baltic Sea region.

Multilateral defence cooperation

International agreements on defence cooperation

Every year, Sweden concludes a large number of international agreements with other states and international organisations. These agreements are known by several different names. A letter of intent (LOI) and a memorandum of understanding (MOU) are two common types of defence agreement.

As the basis for international defence cooperation, both bilaterally and multilaterally, a letter of intent (LOI) is signed by the countries entering into a cooperation. An LOI establishes the basic features of the cooperation that the parties wish to conclude.

Following the signing of an LOI, it is common for the countries entering into a cooperation to also sign a memorandum of understanding (MOU). An MOU usually regulates in more detail the cooperation that the parties wish to conclude.
