Ukraine threatened on Wednesday to forcibly restructure a foreign bond issued by Naftogaz, the state gas company, reviving investors’ fears about the ability of crisis-hit countries in eastern Europe to repay debt.
Ihor Umansky, Ukrainian finance minister, said Kiev had this week serviced some of its external debt after receiving $3.3bn (€4.7bn) in fresh aid from the International Monetary Fund and a pledge for a $1.7bn loan package brokered by the European Union last week.
