Fifa has increased its payments to clubs for the release of players for each of the next two men's World Cups to £298.74m ($355m).
For the 2022 World Cup in Qatar, clubs received a combined £170.58m ($209m).
The move is the central component of a new Memorandum of Understanding between Fifa and the European Clubs' Association, which will run to 2030.
The next men's World Cup, hosted by the United States, Canada and Mexico, takes place in June and July 2026.
Fifa president Gianni Infantino and Uefa counterpart Aleksander Ceferin were present at the ECA general assembly in Budapest for the announcement.
