当今世界若没有联合国，令人无法想象。有一些共同挑战，例如气候变化、生物多样性丧失、贫困和传染病，凭一己之力无法解决，只能通过多边主义共同加以解决。
It is impossible to imagine the world today without the United Nations. There are shared challenges, such as climate change, the loss of biodiversity, poverty and communicable diseases, which cannot be resolved alone but together through multilateralism.
