MOSCOW, Aug 22 - Russia annually supplies about 10 million tons of coal to Ukraine and expects to retain that market, Russian Deputy Energy Minister Anatoly Yanovsky told reporters on Monday.

"There are no restrictions on Russian coal supplies to Ukraine. We are interested in preserving this sales market. We supply 10 million tons a year, mainly coking coal," he said when asked for comment on the first shipment of U.S. coal to Ukraine.
