The initiative, proposed by Hryhoriy Omelchenko, head of the Supreme Rada's committee on fighting crime and corruption, was supported by 288 out of 401 Rada members present at the meeting.
The parliament, which announced Friday that it had extended its session for a week, also inquired about the company's founders and investors, and the circumstances in which a gas agreement was drawn up between and Ukraine's state-owned gas firm Naftogaz. RosUkrEnergo is owned half by Russian energy giant Gazprom and the other half is held by Austria's Raiffeisen Bank.
Under the new gas deal reached with the Russian company, Gazprom will sell Central Asian gas to RosUkrEnergo, an intermediary that will then sell gas to another joint venture in Ukraine, to be set up by RosUkrEnergo and Naftogaz. The deal signed earlier this month ended the long-running dispute between Ukraine and Russia, which cut off gas supplies to the country for a few days in January.
The State Duma, the Russian lower house of parliament, also ordered information on the owners of RosUkrEnergo from its property committee Friday.
