This edition of the AIMAG would have marked the debuts for badminton, baseball5, BMX cycling, cheerleading, floorball, indoor rowing, netball, shooting and volleyball, and would have seen a record-high number of sports in the event's history, at a total of 30.

On November 28, National Olympic Committee of Thailand (NOCT) President Yuthasak Sasiprapha initially expressed possible of Thai's Asian Indoor and Martial Arts Games bid in 2021 to OCA Director General Husain A.H.Z.

Two sport events will be held at the Assumption University Suvarnabhumi Campus in surrounding Samut Prakan Province, which were some of the main venues of the 2007 Summer Universiade.

Cheerleading, Floorball, Indoor rowing and Netball are sports that have recently been approved by International Olympic Committee and are on the World Games program and have low popularity and visibity in certain regions of Asia.

[29] Twelve sports that are part of the current Olympic program (athletics, badminton, 3x3 basketball, football, hockey, roller sports, rowing, shooting, swimming, water polo and taekwondo) were planned to be in this edition's program, however, some of them would have been played in formats that are not part of the Olympic Games.

As the national sport of Thailand, the format of the competitions and the number of events at the last Asian Games would have been maintained.

The three stakeholders were planning to authorize the registration of athletes in 16 individual sports as an integral part of the games.

The emblem of the 2021 Asian Indoor and Martial Arts Games was inspired by the flower garland called Phuang malai, symbolizing the interconnectedness of all participants from all parts of Asia.
