PZB vice-president Maciej Demel has told Polish media that his organisation will not be sending athletes to either the women's and men's editions of the World Championships due to the presence of Russian and Belarusian athletes.

"As one of the first sports associations after the outbreak of the war in Ukraine, we adopted a resolution that we will not compete in competitions in which Russians and Belarusians will take part," said Demel in a report by Sport.PL. 

"Since then, we have not adopted a new resolution, so the old one remains in effect. 

"We are consistent in our actions."

Poland has welcomed more Ukrainian refugees than any other nation since Russia's invasion in February last year, with more than nine million crossing the border.

The PZB's decision delivers another blow to the IBA which has been hit by a series of withdrawals from the Women's World Championships, scheduled to be held from March 15 to 26 in New Delhi in India.

USA Boxing was the first national governing body which opted against sending a team to the IBA's flagship event.

Britain, Ireland, Czech Republic, Canada, Sweden, Switzerland and The Netherlands have since publicly declared their intention to follow suit.

Many of those nations, including the US, have also pulled out of the Men's World Championships, due to be staged in Tashkent in Uzbekistan from May 1 to 14.

Boxing New Zealand President Steve Hartley said it would "prefer" that its athletes did not attend the Women’s World Championships but the organisation has not officially boycotted the event in India.

"This is a mark of solidarity with people from Ukraine in respect to the illegal invasion of a sovereign country by Russia and as a protest against the corruption prevalent in the IBA," Hartley told Radio New Zealand.

"However, Boxing NZ feels ultimately, the decision should lie with the team of women boxers who are attempting to fulfil criteria set by the NZOC (New Zealand Olympic Committee).

"Boxing NZ has provided comprehensive information to our team regarding possible scenarios and in respect to this, we have asked the team to make a decision regarding attending or not and reply to Boxing NZ on Friday."

New Zealand and Poland are members of the Common Cause Alliance (CCA) of nations seeking to prioritise the preservation of boxing's place at the Olympics from Los Angeles 2028, which is in doubt because of governance concerns.

Boris van der Vorst leads the CCA but he had not commented on the boycott movement until yesterday's announcement that the Dutch Boxing Federation Board would not be sending athletes to the Women's World Championships.

The Dutch Boxing Federation criticised the presence of Russian and Belarusian athletes and national symbols at recent IBA events in Abu Dhabi and Marrakesh, which it said represented "another example of IBA’s inability or unwillingness to work towards its reinstatement as an Olympic International Sports Federation" and could "jeopardise the position of boxing as an Olympic sport even further".

The governing body vowed to participate in boxing at the 2023 European Games in Kraków-Małopolska, which is set to serve as a qualifier for next year's Olympics in Paris and the IBA has no involvement with.

The IBA has today revealed its own qualification system for Paris 2024, despite being stripped of the rights to do so by the International Olympic Committee (IOC).

Under the IBA's criteria, this year's two World Championships will be qualification events after the organisation, led by Russian official Umar Kremlev, said the IOC's decision to exclude them was "not acceptable" and "against the principles of boxing".

The IBA has also recently pledged to provide financial assistance for athletes from countries boycotting the World Championships to enable them to participate.

The IOC announced in June last year that it would take over the running of boxing events at Paris 2024, including qualification competitions, due to concerns over governance issues within the organisation.
