U.S. gas trader TrailStone plans to provide gas sale and purchase services on the Ukrainian market from October 2015, the press service of national joint-stock company Naftogaz Ukrainy reported on Tuesday.

Naftogaz Board Chairman Andriy Kobolev said that this is a landmark event, which is evidence of the investors' appreciation of steps taken over the last year to liberalize the gas market and fight corruption.

"TrailStone is our supplier on the European market, and on the Ukrainian market this is a rival. However, its arrival in our market is a very positive event for Ukrainian gas consumers and producers. Operation of the large international trader as TrailStone on our market would promote stable gas supplies, increase liquidity and effectiveness of our market. Our team was trying to achieve this forwarding the reform of the gas sector in Ukraine," he said.

"Our experience shows that these reforms that are being introduced in Ukraine are leading to the improvement of the market conditions for consumers and the increase of investment in the gas sector," Senior Partner of TrailStone Bill Gebhardt.
