In 2008, Ikh Nart Nature Reserve and Anza-Borrego Desert State Park in California became official sister parks. The governor of Dalanjargal soum that manages Ikh Nart, D. Bold, and superintendent of Anza-Borrego, Mark Jorgensen, signed an official agreement in June that will foster relationships between both protected areas.

Anza-Borrego Desert State Park is the largest state park in California encompassing approximately 600,000 acres of unique desert habitats. The park is located in San Diego county and harbors a population of endangered Peninsular Bighorn Sheep.

As part of the agreement, Anza-Borrego provided equipment and training to the staff of Ikh Nart Nature Reserve. The agreement has also led to the development of a ranger program and improvement of border signs.
