KIEV, Aug. 7 – The litigation between Vanco Prykerchenska Ltd. and the Ukrainian government on a dispute over the development of the Prykerchenska oil and gas field may drag on for 1-1.5 years, says Oleh Aleshin, a partner of the Vasil Kisil & Partners law firm, which is representing Vanco in the case.

"I expect the procedure may take a year or a year and a half," he said at a press conference in Kiev on Thursday.
