Belgium/Ukraine

Belgium/Ukraine is an uncommon pairing involving the characters Belgium and Ukraine. It is typically referred to as BelgUkr or UkrBelg, which are both portmanteaus of the two characters' names.

Relationship
Belgium and Ukraine have only briefly interacted in one sketch and one comic, but they (and the female nations in general) are shown to be good friends.

During the 2011 Halloween Event, Himaruya created a comic including most of the female nations who existed at the time, where they are all having a meeting together to reflect on the year. In the meeting, Belgium says that she feels bad that she didn't try a little harder in the past year. Ukraine responds and says Belgium did try hard, and then going on to say she herself thinks she spent too much time in front of the camera.In a 2013 blog post, Himaruya posted a drawing including Belgium, Belarus, Ukraine, and Hungary, in which Belgium is worried about looking plain compared to her flashy neighbors. Ukraine then advises her to "just show off [her] breasts" and make worldwide news.

Fan Speculations
Fans who ship these two enjoy that they have similar aesthetics and personalities, as well as having similar roles in their families as a big sister.

The two countries in real life also have a very long history of economic interaction and trade, even going back as far as the 11th century (1200s).
