KIEV, Nov. 30 - Ukraine’s largest oil refinery UkrTatNafta will boost refining 20% on the month to 360,000 metric tons of crude in December from about 300,000 tons in November, the refinery said Friday.

The plans to boost crude oil refining show the refinery has been successfully tackling the boycott imposed by its main oil supplier, Russian oil company Tatneft, which had suspended supplies in October.
