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.
"Belarus wants large shipments of gas for the low prices of a Russian region, while for its party it does not want to make any political concessions whatsoever," said Mr Yurgens. He accused Belarus of dragging the introduction of the common currency.
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.
