"The war in Ukraine must stop — now. We need serious negotiations for peace, based on the principles of the United Nations Charter. This Council is charged with maintaining peace — and doing so in solidarity. I deeply regret the divisions that have prevented the Security Council from acting not only on Ukraine, but on other threats to peace and security around the world. I urge the Council to do everything in its power to end the war and to mitigate its impact, both on the suffering people of Ukraine, and on vulnerable people and developing countries around the world."
