The European Club Association is to inject 60million euros (£54million) into the Europa League each year from 2018.
The organisation, which represents a number of Europe's leading clubs, has announced it is to make the solidarity payment following consultation with governing body UEFA.
Among the stated objectives when the ECA signed a memorandum of understanding with UEFA in 2015 was to reduce the disparity in financial rewards between the Champions League and the second-tier competition.
A statement read: "With a view to strengthening unity and solidarity in European club football, it was decided to allocate an extra amount of ?50million to the Europa League and ?10million to the qualifying phase."
ECA chairman Karl-Heinz Rummenigge said: "I am pleased that within ECA we manage to reach quick and simple decisions for the good of football.
"ECA is a strong and reliable partner of UEFA. Solidarity is a key pillar of the European club football model, which has always been supported by ECA and its member clubs."
