Hungarian Prime Minister Viktor Orban threatened on Friday to block the next rollover of EU sanctions against Russia unless Brussels helps achieve a restart of Russian gas transit via Ukraine, which was halted on Jan.

Ukraine is ready to consider the possibility of cooperating with European operators on gas transit to the EU, but it is the European Commission that must decide whether the European side needs such transit and whether it is ready to provide it.

(Reuters) - Slovakia's Prime Minister Robert Fico, who has sought the resumption of Russian gas transit through Ukraine, will discuss the issue with European Commission officials on Thursday, his office said on Tuesday.

Václav Bartuška, the Czech Foreign Ministry's Special Envoy for Energy Security, explained this statement. "For the Czech Republic and Europe in general, this does not matter fundamentally," he said.

The ongoing conflict has highlighted the importance of diversifying gas supplies to build resilience against geopolitical risks.
