Financial mismanagement during Wu Ching-kuo's tenure caused the association to incur a large amount of unpaid debt, resulting in his departure in 2017, and being issued a lifetime ban in 2018.

Under Kremlev, the IBA instituted a major restructuring of its executive board, introduced a financial assistance program for national federations, added prize money to its World Boxing Championships, and paid off its outstanding debt.

It also commissioned an independent report by Richard McLaren that found systemic attempts to manipulate match outcomes for money during the 2016 Summer Olympics.

Kremlev's tenure has been controversial, with concerns raised by the IOC over the IBA's increasing ties to Russia after assuming the presidency (including moving much of its operations to Russia and having state-owned Gazprom as sole sponsor for a period), opposition to the independent appointment of judges and referees, irregularities during subsequent presidential elections, and the controversial disqualifications of Imane Khelif and Lin Yu-ting during the IBA's 2023 world championships.

[4][5] Following the Russian invasion of Ukraine, a group of national federations known as the Common Cause Alliance (CCA) demanded transparency over the IBA's finances and the Gazprom sponsorship, and pledged continued support for boxing as an Olympic event.

[6][7] Its 2023 world championships faced boycotts from a number of countries, and false statements by the IBA claiming that they were an "approved" qualifying path for the 2024 Summer Olympics.

In November 1946, a consensus was met to give way for the boxing governing body to regain the loss of credibility due to the behavior of some leading officials in World War II.

While he would be one of the longest-tenured in the AIBA's history, it was one marked by criticism over the association's handling of officiating and judging during boxing at the Summer Olympic Games.

In 2005, the IOC froze US$9 million in funding to the AIBA until it established a "clear timeline and planned actions" for judging reforms; Chowdhry stated that the association was working towards a move to "open" scoring (where judges' scores would be displayed to the audience in real-time in order to provide greater transparency),[17] and was working on changes to how it selects officials ahead of the 2008 Summer Olympics.

[22] In 2010, AIBA launched the World Series of Boxing (WSB), a new semi-professional, international club competition involving teams of amateur boxers competing under a hybrid of amateur- and professional-style rules (including five rounds instead of three, and not wearing headgear).

[26][25] In 2011, BBC News reported via whistleblowers that an Azeri national had made a $9 million payment to WSB SA as a bribe, promising two gold medals in boxing at the 2012 Summer Olympics in return.

In a men's bantamweight Round of 16 bout, Satoshi Shimizu of Japan knocked Magomed Abdulhamido of Azerbaijan to the floor six times without referee Ishanguly Meretnyyazov ever issuing a standing-eight count; the judges then awarded the victory to Abdulhamidov.

[38][39][40] Wu was suspended in October 2017 by the AIBA disciplinary commission, citing his poor financial management and attempts to remove his opponents from the executive committee.

[43] In October 2018, AIBA issued lifetime bans to Wu and former executive director Ho Kim, after a report documented "gross negligence and financial mismanagement of affairs and finances".

The IOC oversaw the qualification events and the boxing tournament at the 2020 Summer Olympics through a task force chaired by Morinari Watanabe, president of the International Gymnastics Federation.

[45][46] The task force adopted the AIBA's technical rules, albeit with some amendments to eligibility requirements and to improve transparency in judging and scoring.

[56][57][58] On 7 April 2021, AIBA's new management signed a cooperation agreement with Russian state-owned energy company Gazprom, through which it became the organization's "General Partner".

[63][64] In September 2021, AIBA released an independent report commissioned from Canadian lawyer Richard McLaren, which had found that bouts leading up to and during the 2016 Summer Olympics had been manipulated.

[65][66][67] The report found bouts had been manipulated for money (up to $250,000), the perceived benefit of AIBA, or to thank National Federations, their Olympic committees, or hosts of competitions for their financial support and political backing.

One of the candidates—Boris van der Vorst (who felt that Kremlev's reform efforts had so far been "superficial")[80]—declared his intent to file an appeal in the Court of Arbitration for Sport (CAS).

[7] At the 2022 European Junior Boxing Championships afterward, the Ukraine delegation was initially prohibited from competing under its flag due to the suspension, resulting in multiple boxers forfeiting their matches in protest.

[87][7] On 5 October 2022, the IBA lifted its ban on Russian and Belarusian athletes competing under their flags, stating that it "strongly believes that politics shouldn't have any influence on sports."

[93] During the 2023 IBA World Women's Boxing Championships that month, the IBA controversially disqualified Algerian boxer Imane Khelif hours before her gold medal match, and stripped Taiwanese boxer Lin Yu-ting of her bronze medal, both reportedly for failing sex verification tests by having high levels of testosterone; Khelif had defeated a Russian opponent—the then-undefeated Azaliia Amineva—in the round of 16.

[97][98] A rival governing body known as World Boxing was launched in April 2023, with its interim board including officials from member organizations of the Common Cause Alliance.

[105] Later that month, the IBA suspended Germany, the Netherlands, New Zealand, and Sweden for their involvement in World Boxing, and Czechia for hosting an event including ineligible boxers; van der Vorst—who was named World Boxing's first president—stated that the suspensions were "yet another clear demonstration of how the IBA proclaims its implementation of reforms, such as the establishment of the Integrity Unit, only to subsequently make authoritative and retaliatory decisions that contradict its own regulations.

The board cited that the IBA had not shown sufficient progress on the concerns raised upon its 2019 suspension, including governance, finances, and corruption.

[108][109] The IOC's decision was upheld by CAS in April 2024,[110] prompting the IBA to file another request for appeal, this time with the Federal Supreme Court of Switzerland; general secretary Chris Roberts argued that the CAS "was biased in favour of the IOC"[111] In April 2024, the IBA announced the formation of a new professional boxing committee.

[115][116] On 31 July 2024, regarding their 2023 decision, the IBA stated that Khelif and others "did not undergo a testosterone examination but were subject to a separate and recognized test, whereby the specifics remain confidential", and further alleged that they "were found to have competitive advantages over other female competitors".
