Ukraine's state-owned gas company Naftogaz said Thursday that Moscow had been ordered by an arbitration court in The Hague to pay $5 billion in compensation for unlawfully expropriating its assets in Russian-annexed Crimea in 2014.
Naftogaz CEO Oleksiy Chernyshov described Wednesday's ruling by The Hague's Arbitration Tribunal at the Permanent Court of Arbitration as a "key victory on the energy front" and said he expected more decisions in Ukraine's favor to come.
"Despite Russia's attempts to obstruct justice, the Arbitration Tribunal ordered Russia to compensate Naftogaz for losses of $5 billion," Naftogaz said.
"Russia must now comply with this decision by its obligations under international law," it said in a statement.
Russia, which launched a full-scale invasion of Ukraine in February 2022, seized the peninsula of Crimea in 2014, drawing a wave of sanctions from Western governments.
There was no immediate comment from Russia or Russia's Gazprom on the ruling. The court in The Hague did not immediately respond to a written request for comment.
Naftogaz said if Russia refused to pay voluntarily, it could initiate a "process of recognition and admission to enforce the award in the territory of those states where assets of the Russian Federation are located."
The company, whose assets in Crimea included Chornomornaftogaz, which produced significant amounts of gas from the Black Sea, gave no further detail of which overseas Russian investments it could target.
However, some high-profile Russian-owned international assets – such as superyachts owned by Russian oligarchs – have already been targeted by governments as part of sanctions following the Ukraine invasion.
Naftogaz had initiated arbitration proceedings with six other companies within the Naftogaz Group in October 2016, noting the arbitration award was made after hearings to determine the amount of compensation, which ended in March 2022.
An analyst at BlueBay Asset Management, Tim Ash, said the ruling was a "huge legal win for Ukraine, and I would think more (is) to come."
Naftogaz has been in talks with investors on a debt restructuring to bring the company out of a months-long default.
