KYIV, April 19 – Ukraine has enough time left until June 1, when Russia will restrict supplies of coal, oil and petroleum products, to arrange alternative supplies of these energy resources, but this issue needs to be addressed, the adviser to presidential candidate Volodymyr Zelensky for energy, ex-member of the NCER Andriy Gerus, has said.

"All these issues are resolved if are dealt with. I'm sure that we can clearly work out ways here, and in June we will have a quite calm and stable situation," he said in the program "The Right to Power" (Pravo na Vladu) on the air of TV Channel 1+1.
