Moscow has frozen the Russian accounts of Roshen, the chocolate empire of Ukrainian billionaire and Euromaidan supporter Petro Poroshenko, on unspecified criminal charges, RFE/RL reports.
Total amount blocked: 2.8 billion rubles ($77 million).
Mr Poroshenko Ukraine's seventh richest man, according to Forbes magazine, with an estimated fortune of $1.3bn.
Earlier, Russia's consumer watchdog banned sales of Roshen sweets in Russia, citing health concerns.
But many observers thought it to be Moscow's response to Mr Poroshenko's political activities rather than concern for the welfare of Russia's chocolate fans. The ban was eventually lifted in November.
