Meanwhile, European Commission President Ursula von der Leyen suggested a similar idea during a July press conference in Strasbourg, France, when she said that they are working on a "legal framework" that would allow them to use the frozen assets to rebuild Ukraine.Meanwhile on Saturday, Reynders said that the $298.9 million (300 billion euros) that the EU froze from the Russian Central Bank could be used as a "guarantee" until Moscow voluntarily takes part in rebuilding its Eastern European neighbor."From my point of view, it is at least possible to keep these 300 billion euros as a guarantee until Russia voluntarily participates in the reconstruction of Ukraine," he added.In a separate interview with Hamburger Abendblatt, Reynders said that he is "reasonably sure" that Russians suspected of committing war crimes in Ukraine would be called to trials at the International Criminal Court (ICC) this year, according to Radio Free Europe/ Radio Liberty on Saturday.European countries and the United States have launched a number of sanctions against Russia in late February in response to the war in Ukraine."
