The World Conference on Human Rights reaffirms that everyone, without distinction of any kind, is entitled to the right to seek and to enjoy in other countries asylum from persecution, as well as the right to return to one's own country. In this respect it stresses the importance of the Universal Declaration of Human Rights, the 1951 Convention relating to the Status of Refugees, its 1967 Protocol and regional instruments. It expresses its appreciation to States that continue to admit and host large numbers of refugees in their territories, and to the Office of the United Nations High Commissioner for Refugees for its dedication to its task. It also expresses its appreciation to the United Nations Relief and Works Agency for Palestine Refugees in the Near East. The World Conference on Human Rights recognizes that gross violations of human rights, including in armed conflicts, are among the multiple and complex factors leading to displacement of people. The World Conference on Human Rights recognizes that, in view of the complexities of the global refugee crisis and in accordance with the Charter of the United Nations, relevant international instruments and international solidarity and in the spirit of burden-sharing, a comprehensive approach by the international community is needed in coordination and cooperation with the countries concerned and relevant organizations, bearing in mind the mandate of the United Nations High Commissioner for Refugees. This should include the development of strategies to address the root causes and effects of movements of refugees and other displaced persons, the strengthening of emergency preparedness and response mechanisms, the provision of effective protection and assistance, bearing in mind the special needs of women and children, as well as the achievement of durable solutions, primarily through the preferred solution of dignified and safe voluntary repatriation, including solutions such as those adopted by the international refugee conferences.

States have an obligation to create and maintain adequate measures at the national level, in particular in the fields of education, health and social support, for the promotion and protection of the rights of persons in vulnerable sectors of their populations and to ensure the participation of those among them who are interested in finding a solution to their own problems. 25.

It is essential for States to foster participation by the poorest people in the decision-making process by the community in which they live, the promotion of human rights and efforts to combat extreme poverty. 26. The World Conference on Human Rights welcomes the progress made in the codification of human rights instruments, which is a dynamic and evolving process, and urges the universal ratification of human rights treaties. All States are encouraged to accede to these international instruments; all States are encouraged to avoid, as far as possible, the resort to reservations.
