The International Basketball Federation (FIBA) and the International Wheelchair Basketball Federation (IWBF) have renewed their Memorandum of Understanding through to 2023.
The latest agreement between the two organisations has a focus on the 3x3 format, broadcast initiatives and marketing of the wheelchair game.
"We are extremely honoured to be considered part of the FIBA family and thrilled to be able to continue to develop further links between the two formats and promote inclusion throughout the basketball community," said IWBF President Ulf Mehrens.
"As a Federation, IWBF is relatively small and young, therefore, to be able to have the support and guidance from FIBA's extensive knowledge and experience is imperative and invaluable to be able to help grow the federation and establish a sustainable and independent future for the sport."
FIBA and the IWBF have worked together since 1992, three years after the governing body for wheelchair basketball was formed.
The IWBF is also recognised as a basketball organisation under FIBA's statutes.
"FIBA has been working closely with the IWBF for numerous years, and we are delighted to continue this collaboration," said FIBA secretary general Andreas Zagklis.
"Our experience and knowledge gained in developing a new discipline within our sport and the excellent broadcasting standards achieved at the FIBA Basketball World Cup 2019 in China last year can only help the IWBF in their vision for the future.
"We look forward to supporting the IWBF over the next four years in their new developments and initiatives."
