It demonstrated the belief and determination of humanity to maintain peace, democracy and human dignity. The process of formulating the Declaration was difficult. But in the spirit of cooperation,countries finally succeeded in reaching a consensus on human rights.The making of the Universal Declaration of Human Rights had great value and significance for promoting world peace and development,and it has had a far-reaching impact on the rule of law in international human rights and the development of the human rights legal systems in various countries. A re-examination and analysis of the process of formulating the Universal Declaration of Human Rights will help us understand the purposes and objectives of the Declaration and review the great value of the spirit of the Declaration to the world today.展开更多
