"In order to survive this difficult period, to avert a default, we need an international donor conference and help from our Western partners," Yatsenyuk said.
The statement comes a day after the Financial Times reported, citing International Monetary Fund (IMF) sources, that Ukraine needs an additional bailout of $15 billion "within weeks" to plug a shortfall in the government budget and prevent the economy from collapse.
Ukraine, currently on the verge of default, is facing a grave economic crisis. Kiev is hoping to save its economy with international financial aid. The additional funding would add to the $17 billion IMF made available in April that is expected to last until 2016. Since then, Kiev has received $8.2 billion in funding from the IMF and other international organizations.
