Which organization must approve the regulations of the national federation regarding players' agents?

The organization that must approve the regulations of the national federation regarding players' agents is FIBA. This is essential because FIBA serves as the overarching governing body for international basketball and establishes the rules and standards that national federations must adhere to in their respective countries. By requiring FIBA's approval, it ensures that player agents operate under consistent guidelines that promote fairness and compliance with international norms. This helps maintain the integrity of the game and ensures that all player transactions and agent activities are conducted according to established regulations.

The involvement of other organizations, such as club federations, player associations, or zone associations, is typically focused on specific aspects of the game or the welfare of players but does not have the authority to set or approve the overarching regulatory framework concerning player agents as FIBA does.
