"We shall continue to defend our rights, we are talking about court proceedings, the court proceedings which will begin early in the next year. If the Ukrainian side makes constructive proposals regarding the settlement of our disagreement we are ready to consider them in pre-trial proceedings," Siluanov said as broadcast on the Rossiya 24 television channel.
Russia has repeatedly stressed that according to IMF rules, a country should be denied aid unless it settles its debts in good faith. On Tuesday, the Kremlin said that Russia would oppose any changes that could be made to IMF rules on the grounds of the specific political situation.
On March 11, 2015, the IMF approved a four-year program of financial aid to Ukraine, which stipulates a $17.5-billion loan to be paid out in a number of installments over the next four years and originally open for reviewing on a quarterly basis.
Ukraine heavily relies on foreign aid to support its economy and to pay debts amid the ongoing armed conflict with independence supporters in the country's southeast.
