"The situation that is emerging in the economy and finances of Ukraine suggests that a number of parameters, which are the conditions of granting Ukraine a Russian bonded loan are violated," the source said.
He also added that under these circumstances "it is likely that Russia will have to demand from Ukraine in the near future early repayment of the $3 billion debt."
In spring, the IMF promised Ukraine a total of $17 billion in bailout loans, to be provided over the course of two years. So far, Ukraine has received two tranches, amounting to $4.55 billion.
Financial assistance to Kiev is also provided by the World Bank, EBRD (European Bank for Reconstruction and Development), European Investment Bank and a number of countries. Overall in 2014, Ukraine received financial assistance amounting to about $9 billion. The total national debt for 11 months of 2014 amounted to $69.3 billion.
In November 2014, Russian President Vladimir Putin said that Russia would not demand Kiev to make an early repayment of Eurobonds in a bid to help Ukraine restore its financial system.
