Why would it not? Divine Comedy and Jack London were both required reading in my Ukrainian school (in translation of course). So was tolstoevsky unfortunately.
I don't mean that non spanish authors are worse (I dislike many of them because they were forced to me too early, when I preferred Dahl or Tolkien), I am just saying that it makes no sense to recommend Shakespeare instead of Cervantes in Spanish Literature class, where they recommend/require books. I can't imagine Russian Literature teachers requiring "Episodios Nacionales" authored by Galdós, a book about spanish history/politics in the XIX century over any russian author about any russian theme.
Because Chekhov, Gogol, Ilf and Petrov, and Strugatsky brothers are better. And dostoevsky definitely is in the retroactively putinist camp, if you don't catch that you haven't been reading enough of him. For mental hygiene alone he should be off that list. Even Bulgakov is better, although not for modern sensibilities. And is a huge waste of time.
That being said, some authors which are definitely great, just shouldn't be on the mandatory reading list for 15 year olds for all kinds of reasons, including for the reason of being russian. The list is not infinite and there is an opportunity cost that is wasted on those two specifically.
