Ukrainian First Deputy Prime Minister Valeriy Khoroshkovsky has said he is confident that there will be no problems with gas supplies from Russia to Ukraine and the EU this winter.

"I think that there won't be any crises this winter, in the near future, because we live under signed agreements. And I also see no problems in the EU, primarily because of the issues that could arise between Ukraine and Russia, so I'm sure that this winter will pass smoothly," he said at a press conference at the third Black Sea Economic Forum, which opened at the Livadia Palace on Thursday.
