Ukraine voiced hopes of setting up a gas consortium with Russia and the EU as early as 2000, but talks stumbled over ex-president Viktor Yushchenko's pro-Western policies.
"Talks are underway; we want guarantees from Gazprom that there will be sufficient transit volumes – no less than 100 billion cu m a year," Boiko said in an interview with the Ukrainian newspaper Segodnya.
"The terms we offer allow us to hope that [we] will agree on the consortium," he said, adding that it was too early to disclose the terms.
In April, Russian Prime Minister Vladimir Putin proposed a merger between Russia's gas giant Gazprom and Ukraine's Naftogaz.
The proposal was slated by the Ukrainian opposition as putting Ukraine's sovereignty at risk.
Gazprom CEO Alexei Miller said that the Ukrainian gas transportation system should become part of a joint Russian-Ukrainian gas venture.
Russian-Ukrainian ties have seen a dramatic improvement since Viktor Yanukovych replaced Yushchenko as president in late February.
