For the first time ever since the People's Republic of China started reintroducing the Takhi or so called Przewalski's horses, four endangered subspecies of wild horses were sent to Mongolia from the Xinjiang Wild Horse Propagation Center in Xinjiang Uyghur autonomous region of China on May 21, 2012. 

The four horses that were sent to Mongolia underwent a 30-day quarantine to prepare for their arrival at the Great Gobi B Strictly Protected Area, Govi-Altai aimag, where they will join 60 other horses.

"The horses are between three and five years old, the best age for breeding. They are distantly related to the horses at Great Gobi B Strictly Protected Area," said Cao Jie, Director of the Xinjiang Wild Horse Propagation Center.

“The horses will first be kept in captivity and gradually released into the wild after becoming acclimated to their new environment”, said Dr. N.Enkhsaikhan, Office Manager at the International Takhi Group, an organization dedicated to saving Mongolia wild horses.

Zoologists from both countries noted that the exchange was just the first of many that would help to optimize the species, maintain genetic diversity and further raise their reproduction and survival rates.

Previously in 2011, the officials of the Government of Czech Republic and Prague city Zoo presented four species of Przewalski's horses that were set free in Khomyn Tal of Zavkhan aimag under the project "Reclaim the Przewalski's horse to Motherland of Mongolia".
