President Alexander Stubb has approved Finland's accession to Nato's Status of Forces Agreement (Sofa) as well as the Paris Protocol.
The Sofa agreement sets out ground rules for military personnel on another state's territory, while the Paris Protocol extends those rules to Nato's central HQ staff.
The president also confirmed changes to national laws in order to accommodate the accession. The Finnish Parliament approved the agreements on Tuesday.
Border visit on Wednesday
Finland's approval of Nato's Sofa Agreement came days ahead of Stubb's first domestic trip as president.
Stubb and his spouse Suzanne Innes-Stubb are scheduled to travel to Niirala and Joensuu in the eastern border region next Wednesday, where they will visit the Border Guard station in Tohmajärvi and then meet representatives of the city of Joensuu.
