Lyon president Jean-Michel Aulas claims the Ligue de Football Professionnel (LFP) will "be studying the problems posed by Paris Saint-Germain's funding".
In June Aulas caused a spat when he suggested the capital city club enjoys tax privileges due to its foreign ownership.
He was publicly censured on Thursday by Saint-Etienne supremo Bernard Caiazzo, who also heads up the Premier Ligue, a body representing Ligue 1 teams' collective interests.
Caiazzo told L'Equipe: "Once again, we have asked Jean-Michel Aulas to focus his comments only on his own club's affairs.
"We have also asked him to refrain from denigrating other clubs, most notably PSG."
Responding on Twitter to a story about the attempts to secure his silence, he wrote: "In exchange, the LFP's board of directors will be studying the problems posed by PSG's funding. Particularly the subject of state aid from Qatar, or what is assumed to be."
