DAVOS, Switzerland (AP) — Ukrainian President Volodymyr Zelenskyy is calling for “maximum” sanctions against Russia during a virtual speech at the World Economic Forum gathering in Davos, Switzerland. He said Monday that sanctions need to go further to stop Russia’s aggression, including an oil embargo, blocking all of its banks and cutting off trade with Russia completely. Zelenskyy also says Ukraine needs at least $5 billion per month. He said tens of thousands of lives could have been saved if Ukraine had “received 100% of our needs at once, back in February” in terms of weapons, funding, political support and sanctions against Russia.
