Eighteen sports venues in Ulaanbaatar and its suburbs are being  planned to be used for hosting the International Youth Green Games in September 2021. Some buildings and complexes are to be rebuilt and some totally new venues will be constructed.

One of the new Olympic sports complexes in Ulaanbaatar has been initiated by the Mongolian Sambo Federation (MSF). It is expected that this complex will be completed by December.

The facility is expected to be finished prior to the Games, and follows the aim of the event to create sustainable goals to keep sport and the Earth safe in the future. The sports complex will be open to both training sessions and international competitions, and will include facilities for football, basketball, fitness and other sports.
