Via Bloomberg - a neat summary of Ukraine's external bilateral trade flows:
Which, of course, shows just how feeble are all the claims about the 'replaceability' of Russian markets for Ukrainian economy. When you take out the Customs Union's total flows of USD 15.71 billion, the entire EU trade flows (for top 20 countries) amount to USD 10.99 billion and these include revenues earned from transit of Russian gas and resales of Russian gas, oil and petrochemical products too. So yes, yes, y.e.s... folks - Russia is obviously a problem for Ukraine's economy and Brussels is obviously a solution... unless you dust out a calculator and tally things up...
