PRAGUE (Reuters) - Slovakia has received a letter from the Croatian government offering to secure a route for additional oil supplies through Croatia amid reduced flows through Ukraine, but it is not clear how this would work, Slovak Foreign Minister Juraj Blanar said in a statement on Friday.

"For what price? What capacity? No one knows that today," Blanar said," reiterating Slovakia wanted the European Commission to act toward Ukraine to fully reinstate flows from Russia, while it was also searching for another solution in case the Commission does not act.
