Ukrainian Energy Minister Yuriy Prodan confirmed Ukraine's position that it intended to file a suit with Stockholm arbitration on revising the price of gas in a contract with Russia's Gazprom.

Prodan made the statement ahead of a three-party meeting with Gunther Oettinger, the EU energy commissioner, and Alexander Novak, the Russian energy minister.

Prodan declined to say whether Ukraine was prepared to pay the $2 billion agreed on at the last three-party talks in part settlement of debt for Russian gas.
