Kolomoyskiy, the ex-Soviet country's second-richest man worth USD 1.3 billion according to Forbes' 2016 ratings, was the owner of Ukraine's largest lender PrivatBank.
The lender was nationalised last December after authorities blamed Kolomoyskiy and other PrivatBank owners for issuing bad loans to cronies and having insufficient capital to stay afloat.
"The ministry of finance of Ukraine welcomes the English High Court order on worldwide asset freezing against Kolomoyskiy and (Gennadiy) Bogolyubov, as well as against six companies they are believed to own or control," the ministry said in statement today.
"These 140 billion hryvnyas are the money of each Ukrainian citizen, each Ukrainian taxpayer and these funds must be returned to the state budget."

Late yesterday, PrivatBank, which holds more than a third of Ukraine's deposits and whose takeover by the state was welcomed by the West, said it had begun legal proceedings in the High Court in London against former owners Kolomoyskiy and Bogolyubov.
PrivatBank added that through the legal proceedings it was seeking to recover over USD 2.5 billion.
Kolomoyskiy, who has fought to challenge the nationalisation, stressed the ruling was a temporary measure.
"This is a temporary arrest for the time of the trial," he told local media.
