KIEV, March 1 – The Customs Union of Russia, Belarus and Kazakhstan violates competition on the Ukrainian petroleum product market and creates obstacles for the operation of international businesses in Ukraine and for the economies of some countries of the European Union, according to the EU-Ukraine Business Council.

"The creation of the Customs Union directly impacts Ukraine: it violates competition on the motor fuel market in the country, is a real economic threat to the Ukrainian oil refining sector, and could affect oil refining facilities in some neighboring EU countries," reads a letter of the EU-Ukraine Business Council sent to First Deputy Prime Minister Andriy Kliuyev.
