On the eve of the 75th United Nations General Assembly, Secretary-General António Guterres offers insights into the challenges facing the world and the solutions offered by multilateralism. At a time of unprecedented global crisis, marked by the COVID-19 pandemic, climate change and other threats, the Secretary-General sees opportunities to shift course away from isolationism and toward common goals. Through global solidarity, he says, the world can build back better and usher in a safer, more prosperous and more sustainable future for all.
