Secretary-General António Guterres briefs reporters on the start of the 80th Session of the United Nations General Assembly. "UN week offers every possibility for dialogue and mediation. Every opportunity for forging solutions. Thousands of leaders’ meetings will take place. I will hold over 150 bilateral meetings myself. I will use every one of them to press leaders to contact each other, to speak directly with each other. To bridge divides. To reduce risks. To find solutions. To get serious," said the Secretary-General.
