Article 48: U.S. Confirms Acceptance of Human Rights of Its Native Americans at the UN
UN Human Rights confirm that the United States supports the United Nations treaty outlining the rights of the world’s estimated 370 million indigenous peoples including in United States
 

The U.S. was one of only four countries – along with Canada, Australia and New Zealand – that voted against the Declaration on the Rights of Indigenous Peoples when it was adopted by the General Assembly in September 2007, a move that followed more than two decades of debate.

Most of the Native Americans (Indigenous Peoples) of United States has different culture and have lost their life while failing to adjust to the present American Constitution. Whatever left is called Alaska Native, Native American topics, Chamorro people, Native Hawaiian, Native American tribes etc. These Indigenous Peoples still live tribal life.
On 19^th December, UN Human Rights confirm the announcement by President Barack Obama that the United States supports the United Nations treaty outlining the rights of the world’s estimated 370 million indigenous peoples including in United States. With its announcement, the U.S. has now joined the other three countries in endorsing the treaty – a non-binding text that sets out the individual and collective rights of indigenous peoples, as well as their rights to culture, identity, language, employment, health, education and other issues.
In addition, the UN Special Rapporteur on the rights of indigenous peoples, James Anaya, issued a statement saying he is “elated” at the US announcement, calling it a “groundbreaking development” for Native Americans and all those who seek greater protection for human rights across the globe. 

“With its endorsement of the Declaration, the United States strengthens it stated commitment to improve the conditions of Native Americans and to address broken promises. Indigenous peoples can now look to the Declaration as a means of holding the United States to that commitment,” said Mr. Anaya, who reports to the Geneva-based UN Human Rights Council in an independent and unpaid capacity. 

The Declaration emphasizes the rights of indigenous peoples to maintain and strengthen their own institutions, cultures and traditions and to pursue their development in keeping with their own needs and aspirations.  

It also prohibits discrimination against indigenous peoples and promotes their full and effective participation in all matters that concern them, and their right to remain distinct and to pursue their own visions of economic and social development.
