LONDON 

If the Druzhba oil pipeline is shut down, Hungary will veto the EU’s latest sanctions package against Russia, the nation’s prime minister said Sunday.

Writing on US social media company X, Viktor Orban said Hungary would secure its fuel supply and introduce countermeasures until oil shipments resume.

“We will not stand idly by while the Friendship oil pipeline is shut down. We will secure Hungary’s fuel supply and take necessary countermeasures until shipments resume,” he said.

“No diesel shipments from Hungary to Ukraine. Refusal of any military loan to Ukraine. No support for sanctions; the 20th sanctions package will be rejected,” Orban added.

Oil shipments through the Druzhba pipeline — a key supply route for Hungary and Slovakia — were disrupted following an attack on Jan. 27.

Hungary and Slovakia have accused Ukraine of using the disruption for political purposes by hindering the continuation of oil deliveries.

After shipments via the pipeline were halted, Hungary and Slovakia decided to suspend diesel fuel supplies to Ukraine in response.

The Druzhba pipeline, also known as the Friendship Pipeline, is one of the longest oil pipelines in the world and among the largest oil pipeline networks globally.

It has been in operation since 1964, transporting Russian oil to several Central and Eastern European countries.
