The Rainbow monument in the Ukrainian capital Kiev, colloquially referred to as the Yoke of the Peoples, further demonstrates the controversial nature of the treaty. Pro-Russian Ukrainian parties, on the other hand, celebrate the date of this event and renew calls for re-unification of the three East Slavic nations: Russia, Ukraine and Belarus.
