After days of negotiations on the assets, the Commission on Monday suggested legal changes to its proposal to secure political buy-in from Belgium.

It gave legal assurances that, under any scenario, Belgium could tap into as much as €210 billion if it faces legal claims or retaliation by Russia, according to the latest text seen by POLITICO. It also stated that no money should be given to Ukraine before EU countries provide financial guarantees covering at least 50 percent of the payout.

In a further concession, the Commission instructed all EU countries to end their bilateral investment treaties with Russia to ensure Belgium isn’t left alone to deal with retaliation from Moscow.

But Belgium said that the reassurances were not enough during a meeting of EU ambassadors on Monday evening, four EU diplomats told POLITICO.

“There will be no deal until EUCO [European Council],” said an EU diplomat who, like others quoted in this article, was granted anonymity to speak freely.

The Belgian government is holding out against using the Russian assets over fears that it will be on the hook to repay the full amount if Russia attempts to claw back the money. But in a further complication, four other countries — Italy, Malta, Bulgaria and Czechia — backed Belgium’s demand to explore alternative financing for Ukraine, such as joint debt.
