Det är samma språk.
By the way, if you listen russian, you find quite a number of swedish words in it, like köpa for example (to buy). Rus is an horse in Gotland, so the Swede say that the russian people are mainly scandinavian. This is not totally wrong when you look at them : tall, many with blond hair and healthy looking. I am learning russian with the few languages I have more or less already (italian, french, english, german, swedish) and it helps me a lot. When I listen to the girls - I am not even anymore looking at them when they are naked - I am hearing many words I already know from other languages. Sometimes it doesn't word, so "tak" in russian doesn't mean thank you as in swedish but "very" or something near - russian is very tricky language, very often no translation is available...
