The head of Ukraine’s competition authority said it has decided to fine Gazprom $3.5billion for abusing its monopoly on the Ukrainian gas market.
The move by the country’s regulator is the latest in the long-standing gas conflict between the two countries.
No details were given by the watchdog of the violations and Gazprom was unavailable for comment.
Gazprom said this week Ukraine owns the company $2.549billion for gas supplied in the third quarter of last year and called for the money to be paid within 10 days.
