‘Ukrainian President Petro Poroshenko has signed into law a bill banning the import of Russian books deemed to glorify the Kremlin, a move expected to further damage Kiev-Moscow ties.

The new legislation adopted on Friday “prohibits the promotion of aggressor states … or [books] that create a positive image of this aggressor state.”

The new measure, which was introduced in September, also forbids literature that urges state coups or promotes wars and racial hatred.

The new law tasks a group of experts to decide which Russian books are acceptable in terms of their content.’
