Eastern Europe accounted for 35 percent of Carlsberg's total volume and 36 percent of operating profit in 2013. Western sanctions and a coinciding slide in the price of oil exports have sent Russia into recession and seen Standard and Poor's slap a "junk" rating on Moscow's foreign currency debt.
The United States said it was ready to increase the sanctions over Russia's actions in war-torn Ukraine, and the EU has said it is looking at piling further pressure on the country's economy in response to an upsurge in fighting blamed on Moscow.
