Denmark and Panama are also part of the latest cohort to affiliate to the governing body formed in April, along with a newly-created federation from French Polynesia.

World Boxing secretary general Simon Toulson hailed the Executive Board's approval of its latest members, subject to Congressional approval in November.

"This is the third cohort of countries to join World Boxing in the last month and is a sign of both the desire for change that exists across the sport and the recognition by National Federations of the critical importance of boxing remaining at the heart of the Olympic movement," he said.

"We have letters of intent from a healthy number of National Federations that plan to join World Boxing and are currently processing a backlog of additional membership applications, so it is clear that there are many countries that want to work with an International Federation that is committed to integrity, honesty and excellence and creating a better future for the sport."

The French Polynesian National Federation has received approval from its National Olympic Committee (NOC) and Sports Ministry, although its athletes compete under the French flag at the Olympic Games.

It is the third Oceanian member of World Boxing following New Zealand and Australia.

It has not previously been part of the IBA, which recognises its own National Federation from French Polynesia.

Denmark is the sixth European nation to join World Boxing, following GB Boxing, England Boxing, The Netherlands, Germany and Sweden.

Panama is also the sixth from the Americas, following on from the United States, Canada, Brazil, Argentina and Honduras.

Mongolia's addition means Africa is the only continent without representation among World Boxing's membership, although the IBA has insisted its recognised National Federation has not left.

"We have been in dialogue with the Mongolian Boxing Federation, and they vehemently deny the claim that they intend to join World Boxing and will resign their IBA membership," an IBA spokesperson told insidethegames.

"One could suspect that this another case of a non-IBA member organisation pretending to be one to damage the IBA’s reputation."

World Boxing said the four members had completed a "rigorous application process", and shown they are "in good standing", have transparent election processes, World Anti-Doping Agency-recognised anti-doping policies, a structured, dispute resolution and appeals process, formal NOC or Sports Ministry recognition and a solid sports programme.

World Boxing is seeking recognition from the International Olympic Committee (IOC), and claims to work to "keep boxing at the heart of the Olympic movement".

An Interim Executive Board including officials disgruntled at the direction of the IBA under its Russian President Umar Kremlev such as GB Boxing chief executive Matthew Holt, USA Boxing President Tyson Lee and former IBA Presidential candidate Boris van der Vorst of The Netherlands has led World Boxing since its founding.

Elections are due to be held at an inaugural Congress on a date still to be decided in November.

Since World Boxing's formation, the IOC has taken the unprecedented step of banishing the IBA from the Olympic movement following a deterioration in relations under Kremlev.

The suspension of the IBA, formerly AIBA, had been suspended by the IOC in 2019 due to financial and governance concerns even before Kremlev was elected, but the sport remained on the Olympic programme and has been assured of its place at Los Angeles 2028.

The IBA's financial support and prize money have proved draws for many National Federations, with the Irish Athletic Boxing Association falling four votes short of the required three-quarters majority to join World Boxing.

Critics argue this financial support is unsustainable for the long term and securing boxing's place at the Olympic Games needs to be prioritised.

The IBA has described World Boxing as a "rogue organisation", and cautioned members to "be careful what you wish".
