Belarus should decide whether it is part of the union with Russia or not. If not, let it buy Russian natural gas for world-level prices, he said.

RUIE President Arkady Volsky said the Russia-Belarus gas dispute would be hopefully settled soon.
He said the problem of Russian gas supplies to Belarus should have been discussed beforehand, before winter set in.
