The Cabinet of Ministers of Ukraine does not set a goal to make public joint-stock company Ukrnafta with large arrears to the national budget on royalties bankrupt, Ukrainian Prime Minister Arseniy Yatseniuk has said.

"As for the debt of Ukrnafta company. Now they started settling current payments. The State Fiscal Service has arrested all assets of Ukrnafta for the sum of the debt of UAH 9 billion. I want to remind you that we're a shareholders in Ukrnafta as a state, and 50% plus one share in it belongs to the Ukrainian people and the task of the government is not to make this company bankrupt, but make it profit-making, return UAH 10 billion to the budget and manage the company as the parliament pointed us to do via the law on joint-stock companies," he said in the parliament on Friday.

Yatseniuk also said that there are no agreements with businessman Ihor Kolomoisky, who is a minority shareholder in Ukrnafta and whose management until recently managed the operations of the large oil producer in the country.

Earlier Kolomoisky said in an interview with LB.ua that there is a confidential agreement between him, Ukrainian President Petro Poroshenko and Yatseniuk on mutual guarantees.

Kolomoisky said it's "a roadmap on the basis of which there is a verbal agreement and a verbal understanding."

"The agreement is divided into two major parts. There are economic things, information [issues], and there are personal issues. I wanted the people whom I invited to work, to whom I was a moral authority, to be safe," he said.

Naftogaz Ukrainy owns a 50% plus one share stake in Ukrnafta and a group of companies related to the shareholders of PrivatBank (Dnipropetrovsk) holds about 42% of the shares in the company.
