(QHA) -

Ukraine will officially ask the Latvian government to act as a third party in three court cases that were open at the European Court of Human Rights (ECHR) to meet Ukraine's claims against Russia.

Ukrainian Justice Minister Pavlo Petrenko said this at a meeting with Latvian Justice Ministry delegates led by Minister Gaidis Berzins, the Ukrainian Justice Ministry's press service said.

Ukraine has filed a claim seeking compensation for Russia’s annexation of Crimea, which Kiev has assessed at over 1 trillion hryvnias (about $100 billion as of the filing date). Prime Minister Arseniy Yatsenyuk has said that Ukraine would sue Russia over every item of property it lost in Crimea.

Russian Ambassador to the EU Vladimir Chizhov said Ukraine’s lawsuit over Crimea had no chance of success.

On March 17, Putin signed a decree recognizing Crimea as an independent state. The same day, Putin and the leaders of Crimea and the city of Sevastopol signed a treaty on the unification of Crimea with Russia, a move that is condemned as illegal by Kyiv.
