Thor's relationship with other pantheon's thunder gods

[Fantasyartist]

Once thing I am curious about is Thor's relationship with other pantheon's thunder gods- such as Slavic counterpart Perun( it seems curious that the Asgardian Avenger has encountered Shango, but not Perun- esp as Russia is closer to Scandinavia than Africa is- and as Donar, he was worshipped by the ancestors of the present day Germans just as Perun was by the ancient Slavs and Balts( the latter called him Perkunas)?
