However, more than 60 international rights group urged ASEAN leaders to postpone the adoption of the declaration and have it redrafted to correct flaws, including the removal of provisions that could limit rights in the name of "national security" or "public morality."
Phil Robertson of New York-based Human Rights Watch said the declaration "as written, does not meet international human rights standards and may, we fear, be used by ASEAN governments to justify violating rights."
U.N. High Commissioner for Human Rights Navi Pillay earlier expressed concerns that the nonbinding declaration was drafted without adequate public consultations.
A final draft of the proposed declaration obtained by AP says "human rights and fundamental freedoms" could be limited "to meet the just requirements of national security, public order, public health, public safety, public morality."
It adds that the "realization of human rights must be considered in the regional and national context bearing in mind different political, economic, legal, social, cultural, historical and religious backgrounds."
Some of the groups welcomed the declaration's opposition to rights violations such as human trafficking. It outlines many of the civil and political rights in the Universal Declaration of Human Rights, including prohibition of torture, arbitrary arrest and child labor.
The ASEAN summit comes as the group has been set back by a rift over how to handle territorial disputes in the South China Sea involving four of its members and China.
The long-simmering disputes are expected to be in the spotlight during the ASEAN meetings. President Barack Obama is to attend an East Asian Summit at the end of the meetings next week.
