Yeah, she appears in "Meeting of the World" in volume 1. She's the blonde with the clipboard (as in the anime). The Ukraine and Belarus strips in volume 2 are alternatively called "Russia's Big and Little Sisters" or "Russia's Older and Younger Sister" by translators, they were adapted to episodes 42 and 43 for the anime.
