Leaders of the G20 summit have called for more aid to Gaza and an end to the war in Ukraine, but the joint declaration lacks specifics on how to achieve these goals. The statement also endorsed a global tax on billionaires and reforms to expand the United Nations Security Council. The declaration received support from all members except Argentina, which challenged some of the language in the initial drafts. The declaration highlights the humanitarian situations in Gaza and Ukraine, but does not mention Israel's suffering or the hostages held by Hamas. It also calls for transformative reform of the UN Security Council to make it more representative and inclusive.
