NIIGATA (Japan): Support for war-torn Ukraine will top the agenda at G7 finance talks on Thursday, but ministers and central bankers will also weigh concerns ranging from banking uncertainty to US debt default fears. The three-day meeting of the Group of Seven developed nations comes with the global economy still unsteady after years of pandemic woes compounded by Russia's invasion of Ukraine, reports AFP. So the talks in the coastal city of Niigata in central Japan are a chance to set out a vision for financial stability before G7 leaders get together next weekend in Hiroshima.
