Ukraine is looking for legal partners and collecting evidence for initiating proceedings against the Russian Federation in international courts in connection with military aggression, Ukraine's acting Foreign Minister Andriy Deshchytsia said in Brussels on Tuesday, according to Ukrinform.

"We are looking for those law firms who could represent the interests of Ukraine. We are also collecting the necessary evidence to bring proceedings against Russia in international courts," Deshchytsia said.

Among the key points that the Ukrainian side will appeal with to the judicial institutions will also be Russia's decision to denounce the agreements on Black Sea Fleet in Crimea.  In accordance with international law, bilateral agreements between countries operate even when these countries are in the "hottest stages" of their relationship.

"Now we have a legal basis for this - after the adoption of a UN General Assembly resolution," Deshchytsia emphasized.
