In international courts, Ukraine will demand that Russia compensates it for the losses incurred by the annexation of Crimea and the occupation of Donbas, and the total sum under the lawsuits will amount to $50 billion, Foreign Minister of Ukraine Pavlo Klimkin said.

"We already know how much we will ask … It's a nine-zero digit [number] and this billion sum can be [retrieved] under various lawsuits. I think as a result, the sum under some lawsuits might add up to the Yukos case [Yukos won $50 billion form Russia in The Hague]," Klimkin said on the "Left Bank with Sonia Koshkina" program on Tuesday.

"We counted everything, even the cost of the natural resources including sand that we can't use," Klimkin said.

He added that no one has ever filed a lawsuit to the UN International Court over failure to execute the International Convention for the Suppression of Financing of Terrorism, and if Ukraine manages to win the case, Russia will face unforeseen consequences, including its isolation.

Klimkin also said that it would take 4-6 years for the court rulings to be made.
