Following the International Olympic Committee's latest statement, World Boxing has called on boxing federations to act now to save Olympic boxing.
As things stand, boxing is not on the programme for the 2028 Los Angeles Olympics.
That could change if the IOC becomes convinced that another governing body can run the sport by early next year.
In April, they rejected the IBA's appeal against the ban on holding the qualifying tournament.
The IOC has concerns about governance, finances and ethics.
“A recognised and credible IF (International Federation) is needed to run Olympic boxing after Paris and World Boxing appears to be the only option,” the IOC said in a statement this week.
The World Boxing Organization, which was formed last April, said the IOC's statement was a “clear and unambiguous message” to all national federations that they must join the organization.
World Boxing Association officials said at a recent press conference that “25 to 30” countries are hoping to join the current 28 member nations.
They have staged three World Boxing Cup events in Cologne, Sheffield and Colorado and have announced several further events, including the first ever Under-19 World Championships in November.
An IOC statement said: “The IOC is not in a position to introduce a new boxing event at the Olympic Games.”
“For boxing to remain an Olympic sport, like other Olympic sports, the IOC needs recognised and credible IFs as partners.”
“The creation of such a new federation, which will respect the IOC's conditions of recognition, now rests in the hands of the national boxing federations and National Olympic Committees (NOCs).”
“All national boxing federations and NOCs who want their boxers to realise their Olympic dreams and win medals at Los Angeles 2028 must now make the necessary decisions.”
“NOCs and national boxing federations hold the future of Olympic boxing in their hands and the action that needs to be taken could not be clearer.”
“Boxing is currently not on the sports programme for the LA28 Olympic Games. To remedy this situation, the IOC needs to secure a partner IF for boxing by early 2025.”
The World Boxing Association responded with a statement: “The IOC has sent a clear and unequivocal message to all NFs and NOCs that if their boxers want the opportunity to compete in the Olympic Games after Paris 2024, they must immediately take steps to join the World Boxing Association.”
“This is the only way for boxing to remain an Olympic sport beyond Paris 2024 and all National Federations must act now if they want to have any chance of having boxing remain part of the sport at the Los Angeles 2028 Games.”
The IBA announced this week that it would offer financial rewards to Olympic medallists.
IBA president Umar Kremlev said gold medallists would receive $100,000 (£79,000), silver medallists $50,000 (£39,000) and bronze medallists $25,000 (£19,000).
Boxers who lose in the quarter-finals will also be given rewards.
