我们正在纪念联合国成立75周年。然而，我们没有理由祝贺自己。我们需要就联合国如何应对当代挑战进行自我反思和对话，以提高其效率和效益，使之能够应对眼前的挑战。
We are commemorating the seventy-fifth anniversary of the United Nations. However, there is no reason for us to congratulate ourselves. We need to engage in self-reflection and dialogue about how the United Nations addressed contemporary challenges to bolster its efficacy and efficiency and enable it to respond to the challenges at hand.
