On July 16, 2020, the National Olympic Committee of Thailand announced that it proposed to the Olympic Council of Asia (OCA) to open the event for athletes from the 24 National Olympic Committees from the Oceania National Olympic Committees (ONOC). The proposal was accepted without any reservations by the OCA and the ONOC,as they proved the success on the 2017 Games held in Ashgabat and 2017 Sapporo Winter Games. The three stakeholders are planning to authorize the registration of athletes in 16 individual sports as integral part of the games.
