Russia has summoned the Finnish ambassador in Moscow, after Finland signed a new agreement on military co-operation with the US.
Monday’s deal grants the US broad access to the area of Finland’s long border with Russia.
Moscow said it would “take necessary measures to counter the aggressive decisions of Finland and its Nato allies”.
Finland joined Nato this year in response to Russia’s Ukraine invasion.
Russian President Vladimir Putin recently accused Nato of having “dragged” Finland into the bloc, and announced the creation of a new military district near Finland’s border.
Meanwhile Finland has accused Russia of channelling migrants towards its territory in a “hybrid operation”, and has temporarily closed all its border crossings with its eastern neighbour.
The agreement signed on Monday allows the US rapid military access and aid to Finland in the event of conflict, as well as joint training of forces.
Russian foreign ministry spokeswoman Maria Zakharova said Moscow would not leave “Nato’s military buildup” on its borders unanswered.
