Kremlin-friendly Hungarian Prime Minister Viktor Orban has refused to supply arms to Kyiv and repeatedly said that Ukraine’s counter-offensive is doomed to fail, irking other EU capitals. And so far, he’s been unwilling to back a new EU aid package for Ukraine.

At the same time, Orban is banking on the release soon of at least some of the more than $30 billion in EU funds for his country that the bloc froze last year over concerns about democratic backsliding.

For Ukraine, the extended debate in Brussels over next year’s aid package is unsettling, particularly with the US Congress also at a stalemate over providing more assistance, particularly military aid, to Kyiv.

Speaking to European Parliament lawmakers on Tuesday, EU Budget Commissioner Johannes Hahn said the bloc cannot be blackmailed by any holdout members.

“Of course you can make things more complicated, more cumbersome if you need unanimity, but we have seen in the past, being crystal clear, that you cannot stop us on doing things,” he said. “Of course it might be more complicated, thinking about Ukraine. Of course we can find a solution which is only including 26 member states.”

Some countries are in favor of finding an alternative solution soon for Ukraine funding in order to increase the pressure on Orban, said the people, who spoke on the condition of anonymity.

However, Spanish Economy Minister Nadia Calvino, whose country holds the rotating EU presidency, and European Commission Vice President Valdis Dombrovskis said on Thursday they aim to reach an agreement within the long-term budget.

“We need to make rapid progress with adopting the Ukraine facility,” Valdis told a news conference following a meeting of EU finance chiefs in Brussels. “Last year we were indeed discussing Plan B. We were able to avoid this scenario last year so I hope we will be also able to avoid this scenario this year.”

Fears about a possible Hungarian veto and reflections over how to circumvent it come as Budapest called for a comprehensive discussion about the effectiveness and sustainability of the EU’s existing Ukraine strategy, which it argues is not bringing results, the people said.

Risk Factors

Hungary told member states this week it wants an assessment of the amount of financial aid and risk factors such as corruption, the people added.

Hungary accused the EU of trying to blackmail it by purportedly tying the release of EU funds to Budapest’s blessing for more aid to Ukraine — something EU officials have repeatedly denied.

“We see an attempt at blackmail on the part of Brussels,” Cabinet Minister Gergely Gulyas told reporters on Thursday. “The commission hasn’t decided whether we’ve complied with their conditions” for the release of funds “obviously with the aim to tying it to other files, such as aid to Ukraine or the budget review.”

Hungary is “ready to discuss” the EU budget — “even aid to Ukraine in the short-term of six months to a year” — but won’t agree to start EU membership talks with Kyiv, Gulyas said.
