KYIV, Aug 5 - Ukraine’s state energy firm Naftogaz said it would not resume buying natural gas from Russia, suspended since late 2015, until Moscow offered it competitive prices and conditions, Reuters reported.

Ukraine was one of Russia’s largest consumers of natural gas until the relations between the two ex-Soviet republics soured in 2014 when Moscow annexed Crimea peninsula from its neighbor.

Kyiv stopped buying Russian gas in November 2015, increasing purchases from Europe instead.
