The EU wants answers from Ukraine about when it will be able to repair the Druzhba oil pipeline that delivers Russian crude to Hungary and Slovakia, European Commission spokeswoman Anna-Kaisa Itkonen has said.

The transit of oil via the pipeline has remained on hold since late January, with Kiev blaming Russia for damaging the infrastructure. Moscow has denied the allegation and has accused Ukraine of using energy blackmail against Hungary.

Hungarian Foreign Minister Peter Szijjarto also insisted last week that the Druzhba pipeline remains in working order and the Ukrainian authorities aren’t restating the deliveries for “political reasons.”

Kiev is “jeopardizing our energy security” because it wants to put the government of Hungarian Prime Minister Viktor Orban, which opposes Ukraine’s membership in the EU, in a “difficult position,” ahead of the parliamentary election in April, the diplomat said.

Itkonen told journalists on Tuesday that the European Commission is in contact with Ukraine to discuss the timeline for getting the Druzhba oil pipeline up and running.

There are currently “no short-term risks to security of supply for Hungary and Slovakia” as they hold 90 days of reserve oil stocks, she said.

Brussels, however, is ready to set up an emergency coordination group to discuss alternative routes to supply oil to the two countries, the spokeswoman added.

The landlocked nations insist that it is impossible for them to fully satisfy their energy needs without Russian deliveries.

Szijjarto said last week that Hungary and Slovakia have asked Croatia to use the Adria pipeline to transport Russian oil. On Monday, Croatian Economy Minister Ante Susnjar confirmed Zagreb’s approval, saying that it “will not allow Central Europe's fuel supply to be endangered.”

Slovak Prime Minister Robert Fico warned on Wednesday that Bratislava could stop supplying electricity to Ukraine if Kiev fails to restart the flow of oil through the Druzhba pipeline.
