After President Vladimir Putin ordered Russian troops into Ukraine in February 2022, the EU sanctioned Russian officials and a host of Russian businessmen, such as Abramovich, while freezing hundreds of billions of dollars of Russian assets.
Abramovich had filed a legal challenge against this.
The court, which also dimissed Abramovich's claims for compensation, noted his role in the Russian steel company Evraz EVRE.L and the fact that steel provided a major source of revenue to the Russian government.
"The General Court dismisses the action brought by Mr Abramovich, thereby upholding the restrictive measures taken against him," the EU court said in a ruling.
"The Council did not in fact err in its assessment by deciding to include then maintain Mr Abramovich’s name on the lists at issue, in the light of his role in the Evraz group and, in particular, its parent company," it added, referring to the sanctions lists.
Abramovich, who also holds Israeli citizenship and is a former owner of Premier League club Chelsea, became one of the world's most powerful businessmen after the 1991 break-up of the Soviet Union. Forbes estimates his net worth at $9.2 billion.
