Belgium insists that it requires solid EU guarantees before approving the plan, ensuring it will not be left to handle Moscow alone if the Russian assets are suddenly to be returned. Belgium holds most of the Russian assets. Approximately $300 billion in Russian assets are frozen, with €210 billion held in Europe. Russia warned European leaders on Wednesday that Russia would take action against any person or country that stole its money. It also cautioned that stealing Russian assets could severely impact European banks and investments.
