 With few natural energy resources, Moldova imports almost all of its energy supplies from Russia and Ukraine.Moldova's dependence on Russian energy is underscored by a growing US$5 billion debt to Russian natural gas supplier Gazprom, largely the result of unreimbursed natural gas consumption in the separatist Transnistria region.In August 2013, work began on a new pipeline between Moldova and Romania that may eventually break Russia's monopoly on Moldova's gas supplies.
