KIEV, March 22 ??“ Ukraine will stay away from building new oil refineries if oil companies move to upgrade existing refineries to make sure they produce high-quality gasoline, Naftogaz Ukrayiny chairman Oleksiy Ivchenko said.

The comment is aimed to encourage Russian oil companies, such as TNK-BP, Lukoil and Alliance Oil, to invest in their Ukrainian refineries that currently use outdated equipment.
