The world must impose “maximum” sanctions against Russia, including a full oil embargo, Ukrainian President Volodymyr Zelenskyy urged in a video address to the World Economic Forum in Davos, which is now underway. “The international community must be ready to use sanctions preventively, not just to respond” to threats in the future, he told world and business leaders in attendance. If these sanctions had been in place in the first place, Russia would not have been able to invade Ukraine, he claimed, calling for total bans on Russian banks and a complete halt in trade.
