Zorig Foundation is a Mongolian non-profit, non-governmental organization (NGO) established in October 1998 after the assassination of Mongolian pro-democracy politician Zorig Sanjaasuren. The Zorig Foundation seeks to spread democratic values in Mongolian society; strengthen human rights, and social justice; as well as improve the system of transparency and accountability of the government to the public. In order to meet the above objectives, the Zorig Foundation concentrates its programs in three areas: Youth and Education, Good Governance, and Community Building.
