Adjacent to or near the Navajo Nation are the Southern Ute of Colorado, the Ute Mountain Ute Tribe of Colorado, Utah, and New Mexico, both along the northern borders; the Jicarilla Apache Tribe to the east; the Zuni and White Mountain Apache to the south, and the Hualapai Bands in the west. The Navajo Nation's territory fully surrounds the Hopi Indian Reservation. In the 1980s, a conflict over shared lands peaked when the Department of the Interior attempted to relocate Navajo residents living in what is still referred to as the Navajo–Hopi Joint Use Area. The litigious and social conflict between the two tribes and neighboring communities ended with "The Bennett Freeze" Agreement and was completed in July 2009 by President Barack Obama. The agreement lessened the contentious land disagreement with a 75-year lease to Navajos with claims dating to before the US occupation.
