Chile signed the United Nations Convention on the Rights of Persons with Disabilities at a ceremony in New York on Monday.
Planning Minister Clarissa Hardy and director of the National Disability Fund, Leonor Cifuentes, attended the ceremony.
Chile will now focus on removing the barriers that affect disabled people and giving them full access to society and communities, government officials said.
The 50-article convention includes chapters on freedom of movement, the right to political expression and access to information, health, employment, housing and rehabilitation.
The convention, which aims to defend the rights of 650 million people in the world, is the first comprehensive human rights convention to be adopted this century. The treaty will enter into force when it is ratified by 20 countries.
The convention was adopted by the UN General Assembly on Dec. 13, 2006. It follows long-standing efforts by organizations concerning disabled people and an increasing international recognition that existing UN human rights treaties failed to fully protect people with disabilities.
