October 24 is the United Nations Day and the 77th anniversary of the founding of the United Nations. United Nations Secretary General Guterres delivered a video message on the same day, stressing that it is more important than ever to safeguard the values and principles of the United Nations Charter. Guterres said that the birth of the United Nations demonstrated the international community's "hope and determination to transcend conflict and move towards global cooperation" after the Second World War. However, 77 years after the founding of the United Nations, the world is now in an era full of challenges: the COVID-19 has been delayed and repeated, the international security situation has been volatile, the road to economic recovery has been winding and bumpy, and various risks and crises have emerged one after another. He said that the United Nations is undergoing an unprecedented test. "At present, more than ever before, we need to implement and implement the values and principles of the United Nations Charter". President of the 77th United Nations General Assembly also delivered a written speech on the same day, pointing out that the United Nations is currently facing two urgent tasks, namely, crisis management and promoting transformation. The United Nations system and all Member States must work for it. Klesch said that in recent years, mankind has experienced multiple global crises. "The increasing natural disasters also remind us to take immediate action to embark on the path of sustainable development." He also said that the United Nations could do more for peace and cooperation in the future. (Liu Xinshe)
