MOSCOW, July 8 (Reuters) - Russia introduced a ban on diesel exports on Wednesday and will begin importing fuel in July as part of measures to address widespread gasoline and diesel supply issues, Deputy Prime Minister Alexander Novak said at a televised government meeting.

"Today, a ban on diesel fuel exports was introduced, and this will make it possible to increase supplies to the domestic market," he said, acknowledging that Russians were concerned about shortages at filling stations.
