Finnish President Alexander Stubb signed amendments to the country’s Nuclear Energy Act allowing the import, transit and transportation of nuclear weapons through Finland, the Finnish Parliament said.
The law will take effect July 1.
The legislation removes previous restrictions on such activities and adapts Finnish law to the country’s new security environment following its accession to NATO.
Finland’s government said the changes are intended to strengthen NATO’s deterrence capability amid a worsening security situation in Europe and Russia’s full-scale war against Ukraine.
Finnish Defense Minister Antti Häkkänen previously said the new rules would allow Finland to fully benefit from NATO’s nuclear deterrence in protecting the country.
Helsinki does not plan to station nuclear weapons on its territory, he stressed.
Stubb has expressed the same position, saying Finland seeks to be a full NATO member without restrictions but does not intend to host allied nuclear weapons on its territory.
