European Union leaders decided on Friday to borrow cash to loan 90 billion euros ($105 billion) to Ukraine to fund its defence against Russia for the next two years rather than use frozen Russian assets, sidestepping divisions over an unprecedented plan to finance Kyiv with Russian sovereign cash. The leaders also gave the European Commission a mandate to keep working on a so-called reparations loan based on Russian immobilised assets but that option proved unworkable for now, above all due to resistance from Belgium, where the bulk of the assets is held.
