The Ejin Horo Banner, also known as Ejin Horo Qi or Yijinhuoluo County, is a banner in Ordos City in southwestern Inner Mongolia, China. It borders Shaanxi Province to the southeast. As of 2009, the Ejin Horo Banner covers an area of almost 5,600 square kilometres (2,200 sq mi), with a population of nearly 160,000, the majority of whom are ethnically Han Chinese.
China's growing economy has led, in recent years, to increased development in the area of the Ejin Horo Banner, with the construction or improvement of roads, transportation centers, and accommodation for travelers and tourists. It is the site of the Mausoleum of Genghis Khan, a AAAAA-rated tourist attraction that does not contain the body of Genghis Khan or, since the Cultural Revolution, any authentic artifacts from his life but which remains important as a cult site in Mongolian religion.
