KIEV, Feb. 14 - Ukraine suggested to replace RosUkrEnergo, a controversial natural gas trader controlled by Russian gas monopoly Gazprom, as the key gas supplier to the country, Prime Minister Yuriy Yekhanurov said Tuesday.

The comment is a reaction to remarks made by Russian President Vladimir Putin last week alleging Ukrainian citizens may have been involved in creating RosUkrEnergo and receiving profits.
